Process Modeling

I have configured a start node that with a receive message trigger that essentially captured information from an email. I have configured all the proper fields but I the "Attachments" field does not seem to work. Documentation has not been particularly helpful in this case.  I have a PV of type Integer that can also handle multiples and the following is mapped to that PV: property(msg!properties, "Attachments", null) When I send an email to the process using its UUID, it captures all the fields correctly except for the attachments. Is my configuration incorrect?

Hello!I have an “Execute Stored Procedure” node in my process model, which sometimes breaks/get cancelled (db timeout mostly). I have optimized the performance of the procedure. However, I was wondering if I could trigger an exception flow right when the node breaks and not after a specific time (because I cannot control how much it will take to break, it varies each time). I tried adding an Error Occurred variable, but it fills up as an output, so when the node gets cancelled, it still hasn’t taken a value.So is there a way to trigger a new flow right when the node gets cancelled?

Hi,We are using a Start Event with a Receive Message trigger configured for Email messages.When an incoming email contains an attachment named Render_2026091902.pdf, Appian automatically creates and stores the document as Render.pdf in msg!properties.Attachments, completely stripping the underscore and the numeric string.Testing findings: Render_2026091902.pdf saved as Render.pdf (truncated). Render-2026091902.pdf saved as Render-2026091902.pdf (works fine). Since this happens during message ingestion at the Start Node trigger level (before process flow execution), is this a known issue or intended behavior related to document versioning suffixes?

Hi Appian Community,I have a situation involving a process model and a process report.I have a process report that retrieves process variables from active process instances and displays the data.For example, suppose we have an existing process model with several process variables. In the future, we add new process variables and need to populate those variables for existing active process instances.My understanding is that we can use “Upgrade Process” to upgrade the existing active instances to the latest process model version. However, the newly added process variables remain null because the nodes that populate those variables were not executed in the original process instance.The challenge is that I cannot simply restart or manually trigger the new node because the process instance are more, and that node was not part of the execution path when the instance originally started we cannot use “Restart Node” smart service.My requirement is:Upgrade existing active process instances to the

I have a web API which expects post request and provides the response after completing few important nodes and other actions are configured Asynchronously . Asynchronous process involves copy document, send data to second external system which are wrapped as multiple subprocesses. Now let's say if any of these asych process fails and I notify the first external system along with process ID, is there a way possible to retrigger the appian broken instance again (ignore the failure reason)? if not can I restart from the broken node itself? does appian provide this capability? (Plugins: Get Processes By Node Status and process-management-services doesn't seem to be working as expected for my case)

I have process model which run subprocess.Both main and sub process already set alert to specific user. However, when error occur on sub process, alert email was sent to all admin in environment (admin@xxx.appiancloud.com) Are there any workaround for this issue? ----- Following is main and sub process configuration.

Hi Everyone,I’m doing some hands on practice by myself, where I face some issues while mapping the record type into a PV. As per the documentation it says we can map record type as PV however when I’m searching my record type while configuring the pv, I’m not seeing my record type. Can someone clarify and guide me whether the action which I’m doing is correct or wrong. Please refer to the SS I have attached. 1st one is my record type. 

What is the maximum number of nodes we can use between 2 attended nodes?

Hi everyone, I’m experiencing this odd behaviour with this specific dataset. The other start processes within the platform are running just fine! The log does not provide me any useful info also.  This is my input example. The start process will run in MNI for each set of input. Sometimes parent process stopped because of this error: Failed to start process. Process Model ID: ButI open the sub-process it run till the end.The parent process will run sub-process for each pv!relationshipToUpdate. Process parameters are provided like below: Below is my pv!relationshipToUpdate example. {a!map(fileId: "FILE_GUID_001",relationshipToRemove: null,relationshipsToAdd: a!map(entityId: "ENTITY_001",entityType: "REFERENCE"),approvalNeeded: false,addRemovalNote: false,documentDescription: "Sample Document 1.pdf",updatedRelationships: {a!map(entityId: "CLIENT_001", entityType: "CLIENT"),a!map(entityId: "EVENT_001", entityType: "EVENT"),a!map(entityId: "CASE_001", entityType: "CASE")}),a!map(fileId: "F

Hi everyone, I encountered an issue regarding saving process variable using a!startProcess -> onSuccess on version 25.4, the fv!processInfo.pv.subCategory was not saved back into local variable ri!checkStatusofChangingCategory. Here is the code: a!startProcess( processModel: cons!NFL_CONS_PROCESS_CHANGE_CASE_TYPE_CATEGORY, processParameters: { subCategory: ri!subCategory, newCategoryId: local!selectedNewCategory }, onSuccess: { ri!saveInto, a!save( ri!checkStatusofChangingCategory, append( ri!checkStatusofChangingCategory,fv!processInfo.pv.subCategory ) ), a!save( local!currentCategory, local!selectedNewCategory ), a!save(ri!subCategory, null), a!save(local!selectedNewCategory, null), } ) The initial value of ri!checkStatusofChangingCategory was null after onSucess, it became [null]. This code worked with version a!startProcess_24r3 ( it successfully saved pv.subCategory into ri!checkStatusofChangingCategory), i want to know the reason why, what am i missing? I'm look

Hi Appian Folks, After community version got upgraded to 26.6, I see process models are not opening at all. Is anyone facing the same issue? 504 Gateway Time-out

Hi Everyone, I have a requirement where a user clicks a notification, and before opening the Summary page, I need to mark the notification as Read. To achieve this, I created a Process Model Start Form that updates the notification status and then displays the same Summary UI. The issue is that the Summary UI contains an email section with a File Upload field. When the user clicks Send Email, I call: a!submitUploadedFiles( documents: local!attachments ) This works correctly when the Summary UI is opened from the Record Summary page, but when it is opened through the Process Start Form, I get the following error: a!submitUploadedFiles() cannot be evaluated in this environment I understand that a!submitUploadedFiles() is not supported in a Process Start Form. Has anyone implemented a similar requirement? What is the recommended approach complete it Would creating a separate interface or dialog just for file uploads be the recommended approach, or is there a better Appian design patte

I have a question regarding the subprocess status shown in the attached screenshot. The subprocesses are displaying the status as "Unattended" instead of "Completed". I have configured the subprocess node to "Run as whoever designed the process model" in the assignment settings. Could you please help me understand why the subprocesses are still showing as Unattended rather than Completed? I've attached the screenshot for reference.

currently I have a subprocess that uses pp!initiator to get the user data to check few validation, and one sometimes the pp!initiator seems to not pick the user from the parent process and i think instead it picks the masteruser (i.e. ABC) which was used to publish the process model. It happens on random instances. Am i missing something.

Hello team, I have a parent process model from which I am triggering child process instances asynchronously using MNI. The child process instances have been successfully triggered and have reached the end node. However, the parent process instance is still showing as Active in the Monitor tab since yesterday. Additionally, when I view the process instance and hover over each node, the Start Process node appears disabled, whereas the End Event node appears enabled. Could you please help me understand why the parent process instance is still in an active state despite the process reaching the end node? As I am triggering child instances through MNI, my understanding is that if I use a Terminate End Event in the parent process, it will also terminate the child process instances. Therefore, I do not think that approach will work for my scenario. Please correct me if my understanding is incorrect.

Hi Team, We have a requirement of querying all processes with an error in our application and send recurring reminder emails to fix that problem (every 5 minutes). Process Report seems to not have such feature. Can anyone please guide on a potential solution here? Thanks!

We have 4 query database smart service nodes in the process model which we are triggering through interface using a!startProcess() based on selected action like add,update and move but business want us to show real time error in the interface if any node fails or process fails, how can we achieve this?

hi i want to create a template and xml data model for Docx from dynamic template. how to code that. and how to create the template. can i get an idea?  it should be like letter. 

Recently i made some chnges in process model smart service, Because of  health check report, in that  we got slow smart services issues  After i made changes then i want know how much of time it take to complete the process model(In the form of milli seconds(MS),where i need to find this time

The Receive Message node has been configured to receive incoming emails that should trigger one of the extraction models within DocCenter. However, this is not happening. Instead, the system only stores the document uploaded or attached to the email within the folder shown in the screenshot. There is also nothing appearing in the system logs from what can be seen. It is unclear what may be missing, possibly a plug-in, as the attachments functionality within the Receive Message node has been deprecated.

Okay, I have a process flow that goes like this: a person enters an interface to reassign a case, maps the emails, etc. Then they enter a synchronous subprocess that connects to an API. Depending on the validation (whether the user clicked "assign" or "reassign"), an asynchronous process runs that sends an email notifying them that the case has been reassigned. The requirement is that after this is done, the user returns to the main screen. The flow works when the email isn't involved, but when the email is, even though it's asynchronous, the activity chaining breaks. Could you help me find a solution for this, or suggest other options? Thanks!

Hi all,   I have a question about process variables behavior in parallel flows and exception handling.   Scenario: - The parent process has a process variable (pv!x) initialized with value = 5. - The process splits into two parallel branches. - Both branches start with pv!x = 5.   Then: - Branch A continues execution, updates pv!x, and reaches the merge point. - The parent process continues and later updates pv!x = 6. - Meanwhile, Branch B is still active and waiting in a task (for example, a user input or a task with an exception flow handling an error).   Question: Will Branch B see the updated value (pv!x = 6) while it is still in that task/exception state, or will it continue working with the original value (pv!x = 5) that was evaluated when the branch started?   In other words: Are process variables dynamically re-evaluated for already running parallel activities, or do they keep the value from the moment the activity started?   Thanks in advance!

How do you decide between using subprocesses and keeping everything in a single process model?
