How to export data to excel in a grid with more than 50 columns? (grid source is database)? Please advise?

Hi Below is the data input to JSON to Excel smart service. {testtName=314120-26000-008 Test Data, testPriority=A, id=17315} When excel is generated the testName is converted to numeric value. testName is of type text. but the smart service has converted it to numeric form. How to avoid the default type conversion while generating excel.

Hi Developers, I am facing issue while trying to send an email containing User Input Task link using function a!urlfortask(tp!id,false) before hitting that User Input Task node.

Hey, I am having below use case and I just wanted to know how I can achieve this in appian.Outlook process -- If anyone sends you a email then you can reply back on top of the email. The old conversation will be seen below in the lastest email that you sent/received as a thread.In the similar way, I am sending an email in the process model when a request is been created from the UI. Upon certain time if I don't get response back from the email which I sent earlier, Then I need to reply to the same email which i sent earlier instead of sending a new email.I want the mails to be threaded as similar to the Outlook/Gmail.I have followed the below discusson and tried the solution, but no luck. I have appended "Re: ___" to the same subject line which i have sent initially upon request creation.[mention:2283fcb4f92743158057945acee45483:f586769b0822468ab7f3a94d480ed9b0]Any response on this would be greatly appreciated. Thanks in advance.

I was getting this error Expression evaluation error [evaluation ID = 2f483:71082] : Appian object error. Details: Failed to execute query in thread for: EntityBackedQueryExecutor []  when i open a task 

Hi Team, I am starting the process model by triggering us start form, once a user click submit button in the interface ideally all the role input data should be transferred to process variables. But in my scenario one of the Rule input data is not transferring to the process,When is the click a submit button the data is getting saved in a role input properly ri: emailBody(Text)But the same data is not being transferred to the process model please refer the images below pv: emailBody(Text)

Hi All, Asynchronous Start Process smart service runs as synchronously because sub process has activity chaining. Our question is old Start Process smart service runs synchronously as there is no option in earlier version, but newer version also runs same way then we have to Async sub process in that case. Any reason for this issue? Using on premise Appian with 25.2 Thanks!

I am facing a weird issue while sending mail using send email smart service. I am getting everything that is required to send a mail. I have valid email ID, body that is needed, subject and everything. The process model is also getting executed successfully but email are not being sent. We also tested this before one day of this. At that time, we were getting mails. We didn't do any deployment since then but it is not working in both environment now. This is the common process to send an email. It is working elsewhere, just not sending mail for one scenario which was working before. Attaching screenshots of configuration. Please suggest something.

I am facing an intermittent issue with sub-process execution in Appian. A sub-process completes successfully and, in the parent process, the sub-process node shows as completed. However, the main process does not advance to the next node and remains stuck at that point. This is happening both in multiple process models and at different points in the flow. The same process models have executed successfully in other test runs, including cases where the same sub-process followed the same Flow and completed correctly. There are no errors logged, and the sub-process always completes correctly. The only common pattern I have noticed is that the issue tends to happen in process instances that have been running for a long time and have traversed many nodes and multiple possible paths before reaching the sub-process. Has anyone encountered a similar behavior? Are there known engine limitations or considerations (e.g. long-running process instances, high node count, memory/state handling, or sub

Hello, We have recently upgraded to 25.4 version. The deprecated plugin 'Execute Stored procedure' is removed, and Appian inbuilt function is used to execute the stored procedure to load the data in cloud DB. However, the node is failing with error - Query execution was interrupted (max_statement_time exceeded). Kindly help what is missing and if the 25.4 version has any specific config to set the max statement time. On some of the node receiving following error - ORA-01013: user requested cancel of current operation https://docs.oracle.com/error-help/db/ora-01013/. The node configuration is same in both the cases. Regards, Nirupama

Hi, We are experiencing slowness in processes calling other processes using start process smart service asynchronously. Its taking 1-4 seconds in some cases just to invoke the process using start process smart service. Has anyone experienced this kind of a behavior while using start process. Regards, Vikrant Bhardwaj.

We have a process model that is the same in our dev and test environments (compare and deploy shows Not Changed). In this user input task, the interface is also the same between dev and test environments. However, in our dev environment, the interface shows up normally in this user input task, but in our test environment, it shows up as this. Even if I try to search for the interface myself so I can relink it to this node, it still shows this error. On the UI, instead of showing the most updated version of the interface, it shows an old version from several months back. If I check version changes to the process model in the test environment, it still says there is an interface in this user input task. If I check process model versions from several months back, I still see this error on the user input task, even though I know several months back when I was testing this process, everything looked fine. If I check the UI in dev, everything looks normal, so dev is functioning fine, and co

I'm not sure what the purpose of a Quick Task is. Do you know any YouTube video to see an example of use? Thanks in advance.

HI We are exploring a potential integration pattern and would appreciate guidance from the community on whether this is feasible within Appian’s integration capabilities—specifically around user-specific authorization with Box when a process is triggered via email. Use Case Overview A user sends an email containing a Box folder link to a designated mailbox. This email triggers an Appian process via Process Model Email Polling (this is currently working as expected). The process then attempts to download documents from the referenced Box folder. The key requirement is that Box access must respect the sending user’s specific Box permissions. Current Authorization Approach We plan to use OAuth 2.0 Authorization Code Grant for Box authorization from within Appian. We are intentionally not using the JWT approach, as it requires Box admin-level permissions and provides broader access than desired. This approach works well when initiated from the Appian UI, whe

I want to generate an excel sheet using JSON to Excel converter plug in. Even though I am passing the json correctly, I am getting an error message:

When using a!startProcess within the interface button, the process instance is successfully created and completes as expected. However, despite the successful execution, the a!startProcess function moves to the onError block, resulting in unintended error.

I have deployed a new package which contains a expression rule doing some calculation, into Production Environment and its running Live ,Somehow its failing in production, and there are around 300 instances which got failed due to error of this Expression Rule which called in a Script task, May i know how to fix this Error,Can someone suggest us some possible and most efficient Ways to do this. Thanks in Advance.

Can anyone tell why its showing only 101 item even though the ids passed are 1000 

I have a process model that loops itself. In the screenshot I'm having an error in start process which I labeled as Node 2. The error is the max subprocess depth limit of 100 would be exceeded. My question is, if the subprocess depth limit is 100, the main process as count 1 in the process depth counter, the next start process smart service as 2, and the recursion as 3. Shouldn't it run only around 50 times? I checked logs and the process run 100 times, before getting an error in Node 2 in the screenshot. I think my calculation is just wrong but I need clarifications on how is this calculated.

Good Afternoon, I am utilizing the pdf doc from template smart service to generate a pdf that is a snapshot document of a form that has been filled out by a user on the site.  The template I need to use in the smart service is an editable pdf template of the form that I then dynamically fill the inputs from the user into the template to generate the document.  The Problem:  The produced PDF document from the smart service is still an editable version while I need it to be a read only.  Does anyone have a solution for converting the generated new PDF from the smart service from editable to read only before I send it to off site storage?  Thank you

Receiving this error when I click on Clear Filters in the Monitoring Process Activity page: Appian version 25.4

I've created a process that utilizes the PDF Doc from Template Smart Service that was working correctly until this past weekend. There were no changes to the process model or to the template used to create our documents. I use to see a fully filled out pdf and now am seeing a blank page with empty boxes that display a value when clicked. Has anyone encountered this before?New behavior:[View:/cfs-file/__key/communityserver-discussions-components-files/14/20251124_2D00_2151_2D00_03.8000270.mp4:320:240] Previous behavior: [View:/cfs-file/__key/communityserver-discussions-components-files/14/20251124_2D00_2154_2D00_57.6194333.mp4:320:240]
