Initially, I considered using deployment packages to track changes. However, I noticed that once changes are pushed from UAT to Production, the environments become synchronized. As a result, all objects appeared in the deployment package; however, the ones that were initially modified before being pushed to Production are no longer listed as 'modified.' This makes it difficult to track the specific changes made during that deployment.I'm looking for a reliable approach to maintain visibility into code changes with each deployment. Has anyone found a good solution or best practice for this scenario?

Hi Everyone, I am trying to understand how the internal messaging service and Kafka Zookeeper work in Appian .I am trying to figure out what impact it would have if Kafka goes down on one of the nodes in a 3 node cluster due to storage issues or some other reason. One thing I can guess is that the application's performance might decrease, and writes to the data service could also be impacted. Are there any other potential issues that could arise? Thanks                                                           Udhaya

Hello, I have a on-premise installation with some Web API Authentication -> Third Party OAuth 2.0 Clients configured. However, we discovered that the JWKS Public Key file was removed, apparently directly from the server, as when trying to open them I'm getting the following error that for security reasons I cannot add any screenshots of: Error in a!forEach() expression during iteration 1: Expression evaluation error at function fn!content_appian_internal [line 40]: Invalid Content ID. I wanted to identify in the server where these configuration are being stored and if it's possible to restore the deleted file somehow, the only option for the moment is to delete the configuration and manually add it again. Also, I'd like to locate the root cause, just in case there's an automatic process running in the server making these deletions to prevent it from happening again. Thank you

Can someone please explain what are major pros and cons of process driven and  db driven task and in which use case we should consider db driven and process driven approach.

Hi all, We have just upgraded Appian from 23.3 to Appian 25.2 and when starting Tomcat we have found the following error in the log: [PUT], host [http://localhost:9200], URI [/user-activity-8-0/_settings?master_timeout=30s&timeout=30s], status line [HTTP/1.1 401 Unauthorized] {"error":{"root_cause":[{"type":"security_exception","reason":"unable to authenticate user [appian] for REST request [/user-activity-8-0/_settings?master_timeout=30s&timeout=30s]","header":{"WWW-Authenticate":["Basic realm=\"security\", charset=\"UTF-8\"","ApiKey"]}}],"type":"security_exception","reason":"unable to authenticate user [appian] for REST request [/user-activity-8-0/_settings?master_timeout=30s&timeout=30s]","header":{"WWW-Authenticate":["Basic realm=\"security\", charset=\"UTF-8\"","ApiKey"]}},"status":401} at org.elasticsearch.client.RestCli

What are the steps involved to migrate appian from on-prem to cloud.

Hi everyone, We're building a bi-directional integration between Appian (BPM) and an external multi channels systems CRM, Mobile, Kiosk, Corebank etc. We have two architectural approaches and are looking for insights or best practices from the community: Approach 1: Task-ID Driven • CRM receives a generated Appian task ID via API • CRM later calls a second Appian API to complete that specific task by its ID Approach 2: Event-Driven Integration with Correlation ID (Using Appian Events) A shared correlationId (UUID) is generated and passed between CRM and BPM. Appian subprocesses register to Receive Message Events or wait via correlation-aware logic. CRM communicates by sending events (e.g., KYC_COMPLETED, DOCS_SUBMITTED) using a unified API. Appian routes events internally using correlationId + eventType. What I'm Looking For: Is there an Appian-recommended best practice for choosing between task-based vs event-driven integrations? Are Receive Message Events and cor

Hi everyone, We’re currently in the design phase of a large-scale Appian BPM implementation for a bank. Appian acts as the backend processor for multiple business domains — including Loan Origination, KYC, and more — with all front-end channels (like CRM) integrating via Kafka events. To give context, here’s a simplified version of the incoming JSON payload from CRM to our Appian BPM: Our Design Question We’re wondering whether our database design should mirror this JSON structure, or whether we should use a normalized model that separates document references into a central table. To scope the question further: We’re using a DMS (Document Management System), and every attachment UUID points to a file stored there. Documents can belong to any entity (Applicant, Collateral, Product Info, etc.), and multiple documents can be associated with each entity. Processes vary, and different document types may be required at various stages (requested from the C

A client reported that one of their processes has been quite slow. Their process relates to a Wizard style interface that the user needs to populate before submitting the task. However, the interface does not perform any heavy queries or expressions. When reviewing the Health Check report, what should you do? Ans:- a.Investigate the slow activity-chained process flows (as multiple User Input Tasks might be linked together) and merge these into a single interface b.Investigate the number of unattended process loops (as multiple User Input Tasks might be linked together) and merge these into multiple node instances where possible c.Investigate the interface size and review the historical performance trends of the interface (as it might indicate an environment issue) and make adjustments where necessary

Hello All, After upgrading to Appian 25.2, we noticed that deployments triggered via the deployment-management/v2/deployments API are taking significantly longer to complete. Previously, the same deployment process would finish in around 8 minutes, but now it takes over 3 hours. From the Tomcat logs, we observed errors related to constant updates during the deployment process, which may be contributing to the delay. We also attempted to stop the in-progress deployment by restarting application servers and engines, but the deployment continues to remain in-progress and is not cancelled. We have already raised a support ticket with Appian, but in the meantime, checking with the community: Has anyone else encountered similar issues after upgrading to Appian 25.2? Is there any other way to cancel or forcefully terminate an in-progress deployment initiated via the API? Thank You, Sneha.

Hi everyone, We’re building a large BPM platform in Appian for a bank. It handles multiple core processes like Loan Origination, KYC, and other services. We’re also integrating with both CRM and a Document Management System (DMS) — so document handling is a key topic for us. Our Setup CRM sends us structured application data via Kafka events. We use a central table called BPM_PROCESS_MASTER to track each case (with caseId, correlationId, processKey, etc.). We built a shared table BPM_DOCUMENT_LOG to store documents with fields like: processId entityType entityRefId documentType AppianDocId (if it’s stored in Appian) DMS_UUID (if it’s stored in our DMS) This setup gives us flexibility: We can store documents at any level (applicant, guarantor, collateral, etc.) We can handle new document uploads mid-process (like if Credit asks CRM to re-send more docs) It keeps our business data clean and avoids spreading document fields everyw

Can we configure Appian Cloud so that a specific Site (e.g. https://<mydomain>.appiancloud.com/sites/customer) is publicly accessible from outside our corporate network, while restricting access to the Design environment, Admin console, and other internal Sites to only whitelisted IP addresses?

Hi there, As a result of a process, a CSV file is output, and I want to store that file in AWS S3. Also, when needed, I want to be able to copy the file in S3 to the Appian Knowledge Center by pressing a button. I want to achieve this by connecting via AWS Private Link, not via the internet. To achieve this, is there any way other than using Lambda, etc.? There is an Amazon S3 Utilities plugin, but it seems to connect via the internet, so I don't think it meets the requirements. Thanks

Hello Team, Our Appian platform is on Cloud. Does anyone know how to download the Identity provider metadata file that has configured for SAML Authentication?  We want to update the saml end points for the certificate renewal. Thanks, Ramesh

I need assistance resetting a user’s password in our Appian environment. Due to security restrictions, we do not have SMTP/email functionality available, so the standard “Forgot Password” workflow cannot be completed.  Current Behavior I navigate to the Administration Console → Users Locate the user record for John Doe Click “Reset Password” System prompts that a reset email has been sent No email is sent because SMTP is disabled

Hello, We have moved from version 24.4 to the new 25.1 and we have encountered some errors in interfaces. The gridFields that were in version 24.4 had a RecordData as data collection in which they were configured with some Fields with relationships a!recordData( recordType: recordType!example, fields:{ recordType!example.example ... }) Now in version 25.1 the interface is broken because the action records have lost their ID To fix it, we added the base field recordtype!exxample.id to the field so that it obtains the data since it gave an error and the action link did not appear. a!recordData( recordType: recordType!example, fields:{ recordType!example.id  <----- recordType!example.example ... }) Is there any explanation for this? Thank you

Hi everyone, I'm working with Appian 25.2 on Windows, and I want to change the default HTTP port from 8080 to 80. Here’s what I’ve done so far: I did not modify anything in <APPIAN_HOME>, as per Appian's official recommendations. I located the file tomcatResources.xml inside <REPO_HOME>\conf. I added this connector definition: <Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="443" /> I ran configure.bat from the root of the configuration repository. It completed successfully with no errors. I did not start the Appian environment, I only checked the generated file at: <APPIAN_HOME>\tomcat\apache-tomcat\conf\server.xml And I noticed that the port is still set to 8080 instead of 80.  What else should I check or configure to get the port changed properly to 80?

Difference in Write to Multiple Data Store entity and Write to Data Store entity?  When we need to use the multiple data store entity?

Hello everyone, I believe I created a real issue by deleting documents I should have left alone. My goal was to make environment B identical to environment A.  There were existing files in environment B so my approach was to delete everything I could and then import everything from environment A.  To clear away everything in environment B I hard deleted all application files by going into the application in designer, check the box next to the file name, delete, and confirm delete.  Once all files were deleted I would then delete the application itself.  Once all applications and their corresponding files were deleted I then went after files that lived outside of the applications.  I'm fairly certain this is where I created my problem.  I deleted documents that I now believe were being used for the appian user profile pictures.  The documents I deleted had the format of <username>_180, <username>_90, <usernam

Hi All, we have encountered the delay in the execution of the process node (write Records) in the process model.

Thanks in advance!! regards, Manoj Yadav.

I want to display the data on the search screen when I return from the summary view using the back button.

Hello, My app has a series of reference data stored in a separate table/RT.  We've permitted the user to manage that data as the values (slowly) change over time.  Part of that management is to disable selections for future use by making them inactive (isActive = False).   Dropdowns are used to access the reference data for creation and editing records.  Only the active values are made available in the choiceValues/Labels to prevent use of outdated information. The problem is in dealing with "historical" data.  There are active records created the week previous that include a reference value that was made inactive=True this week.  Now anytime these types of records get edited, the reference to the retired data causes an error because selected value is not on the current list of choiceValues.  I could lift the isActive = true filter on edit vs. create new record, but some of the reference values are years old and not appropriate f

Hi all, I'm using the out-of-the-box (OOB) "Download as Excel" functionality on a paging grid in Appian. One of the column values in my grid is a dash (-), which is displayed correctly in the interface. However, when I export the grid using the download button, the dash is exported to Excel as '- (with a leading single quote). It seems Excel is treating it as a text value, but I would like it to appear exactly as -, without the quote. Has anyone else experienced this? Is there a way to prevent the single quote from being added during export? Thanks in advance for any suggestions!
