Process Modeling

The process model is showing as invalid, but there are no logs indicating the reason for the invalid status. I’ve reviewed all subprocesses, and they appear to be valid. What could be the possible cause? Is there a standard or recommended approach to debugging this issue?

I am doing example "Build an Application: Step 10". This is where you build from scratch a simple process model to enter in a maintenance request. Everything work fine from the process start form to writing the data back to the Maintenance recordType. However, the XOR cancel does not work. When I click it, the flow process as if I am submitting the form. I followed the step by step instructions exactly. I even completely deleted the XOR and is corresponding End node and rebuilt. Still same thing. 

My company has a huge process model, includes hundreds of nodes and a lot sub process, there are a lot form nodes in this pm, they all having activity chaining and assigned to same user, we are developing on this pm and also have changes on ui and forms. When user finish and submit this form, will automatically redirect to next form node and do next form. Form data is complex list of cdt saves in process variables, and will write to db The problem is, our form can add multiple blocks of a same form, this can make list of data very big, when we added too many form blocks, likely 30 + blocks, then submit, then it shows a little action complete banner, and redirects to home page, but you can countiune this process and find next task in current user’s tasks, user can countiune task with no error. And in process instance monitoring, no error.  I guess it’s data size problem, but I didn’t find a way to resolve this problem, some times there will be a huge form.

Hello, I am trying to capture the attachments sent by email when starting a process by email is configured. I have tried to store in a variable (multiple) of type document the following data but the variable remains null: - fn!property(msg!properties,"attachment",null()) - fn!property(msg!properties,"Attachments",null()) And I also tried just msg!properties.Attachments but I get this error by email:

Hi everyone, I’m working on a task where the expected output involves a grid that allows multiple selections. The user can select three checkboxes and then click a button. Upon clicking, a small popup should appear asking for a meeting name corresponding to the selected three IDs. I tried implementing this using a related action, but it only works for single row selection. It doesn’t support multiple row selection. I also tried using a startProcess link, but it opens a large popup. Since we’re only filling in a single text field (the meeting name), it doesn’t look good occupying the entire screen. Is there any way to achieve this more effectively? Thanks in advance!

I have a scenario to create an excel file with 3 sheets. I have used the export data store entity to excel smart service in the model back-to-back (3 times). I gave the folder to the first node, configure the output document of first node and provided the document to update field in second and third nodes respectively in order to update the same sheet. The process executes and returns the excel document that i expected. But in the history, after the execution of first node, i have one document id generated and after the execution of last excel node, another new document id is generated. At the end of the process, i write the documentId in a table. In the mentioned folder i can see only one document which is the first one. Please let me know what should i need to do? Thanks In Advance,Vishnuvarthan.

Hello , i am trying to build a PM that sends mails to users(81 in total), i put delay between the emails 25 seconds , but after some repetitions (33,42,72) random each time PM stops with the error : Failed to send emailIs there a limit of email that a sigle PM can send ? or something

Hello, I have a Web API configured to trigger when a process model encounters a failure. The logic to detect the failure in the API's body section is as follows: error_code: if(fv!processInfo.pv.success, fv!processInfo.pv.errorCode), error_description: if(fv!processInfo.pv.success, fv!processInfo.pv.errorMessage, "Failure in process model") The issue I'm facing is that the process model executes successfully — no errors occur, and I receive the expected data in the response. However, the API still returns the error message: "Failure in process model". Also, the errorCode and errorMessage passed from the process model are empty. Could anyone help me understand why this is happening? Is there something wrong with how the condition is structured? Keep in mind it used to work prev and is working perfectly in other processes/web APIs?

Hi All, I'm experiencing a quirky behavior. I am a system administrator and have designer group access but unable to edit process model expression editors of script task, email nodes etc. I have also tried in Designer view and made sure it is not analyst view. Please advise. 

Getting error in the script task. I'm trying to pass the below jsonPV in PM.I want to store the id values in DB as separate row

Hi All, I'm using for the first time the Export Data Store Entity to Excel Smart Service to add data to an existing excel template (saved as a doc in appian) (Exporting data to a formatted Excel sheet). Once I add the data to the excel it seems it adds it in the same row and erases anything on the same row that was there before, I'm trying to add the new data only in one column, different rows instead in one whole row. Does someone know if this is possible or how I should be configuring the parameters. customCellPositions List of Text String (Optional) Array of cell positions where custom cell values should be added. customCellValues List of Text String (Optional) Array of values to be added on the specified custom cell position. Or if you could recommend a different smart service to achieve this? Thanks in advance

Hello, I'm currently learning about the various functions of Appian to understand how powerful it can be. At the moment, I'm facing an issue with creating an approval process that has a condition where at least 2 out of 3 approvers must approve in order for the flow to continue. This is what I have configured in the user input task node so far.The problem I'm facing right now is that I don't know how to update the value of pv!approvalResults (which is a list of text) when each approver takes an action. Could you please give me some advice?

When trying to download a Word document from Appian using the Word to PDF Smart Service,the document is successfully parsed data and document is download from the interface.However the document is opened in MS word it throwing error as attached in the thread. Note: 1. The template uploaded here is in word docx format. There is not security/permission applied on the document. 2. No error is observed on the process model / interfaces.  [mention:6befada3df63445abdcce1603d065926:46448885d0e64133bbfbf0cd7b0fd6f7]  [mention:dd6011d950fa4085a72d4094ed65570c:23b05a61c3e5445190d9bfa00453bce4] 

If the integration fails it will show the error in the same UI but the already entered values are missing on the UI .how can I keep those details stay on the 2nd UIT 

Hi All, In this processmodel I'm trying to show the integration error on the same UserInputTask (UIT) where we entered details .It below throws.

Hello All, I have a scenario where I am calling the process from web API, to get this completed faster I have added few flows in parallel using AND gateway and these paths has to complete to return the response from web API hence I have applied activity chaining on both the flows. With this implementation I have observed that, even we are having parallel flows using AND, because activity chaining, only one path is executing first and then other is starting which delaying time of execution. Why chaining is over-passing AND functionality here? Any thoughts on this? Please find below example process. Thanks! Priyanka

Hi Appian Gurus, In an application when I click on a link of type Start process link I am getting the below mentioned pop up, how to resolve this and how to prevent this kind of errors occuring in future Thanks in advance

I'm working on an Appian application where I’ve built an email template that includes a 'View Details' button linking to a specific process instance. The link is generated correctly and points to the intended process instance. However, when I click the 'View Details' button from the email, I get the error: 'Cannot find the main Appian window. Reopen that window and launch the modeler from there.' Why is this happening, and how can I fix it so that the link works correctly from the email?"

hi... i have deleted an ri-variable in a form. I then go to the process that has the form as the start form - delete the interface and select it again as the interface.The deleted variable is no longer visible as an input variable. It has also disappeared from the process variables.If I want to save the process, I still get the error message:There was an error in an expression in Process Model Properties at Process Start Form : Variable(s) not found: ri!cancel before: after: What can I do here?Where else can I delete the variable?

Hi All, I have a query rule as below and when passing to the process model, output is coming weird as Data: object,object. Please help!! Expression rule output - [startIndex=1, batchSize=1, sort=[field=updatedDateTime, ascending=false], totalCount=-1, data=[caseId:123,IDNumber:122567,caseStatus:On-Hold/Request for Info,clientName:user155678,folderId:1267888], identifiers=322] When same rule passed and saved to pv of type datasubset in process Model: [startIndex=1, batchSize=1, sort=[field=updatedDateTime, ascending=False], totalCount=-1, data=[object Object], identifiers=322]

Hello,In the scenario below, I understood the reply, but could you explain me how to implement an "Event Subprocess" please ?I don't see any simple option or such smart service in the process modeler palette. And in the "subprocess" service I don't see how it can be triggered by an event.Do I need a Rule or Timer event, or "Receive Message" to activate the supProcess?If you have a tutorial on internet, it would be perfect :-)Ms. Durant is working on an Appian application to track customer orders for a retail company. The application needs to trigger a series of tasks to validate order details, check inventory, and process payments. However, if the payment fails, the task flow should automatically halt and notify the customer service team to follow up. Additionally, the process must be able to send notifications to the customer about their order status at each stage. What is the best way for Ms.

I have created a process to loop through each row in a record, and for each row, I have defined a set of instructions to execute. However, I'm encountering an issue where the process enters an infinite loop. In the "Get Script Task," I am using a simple query to retrieve data from a record. I attempted to save the query result in a multiple variable, hoping it would allow me to loop through the rows correctly, but it still results in an infinite loop. the problem is im not able of retreiving a single value of a frild form the record , its concatenating all the values in the output  inside the variable ,and not one by one which cuases this infinte loop , and this what im passing for codice progetto : pv!ImprotPregressoPC['SC Import Pregresso PC.fields.codiceProgettoConnessione'] how can i make it retieve one by one every loop?

Hi all, I want to automate the change of the deletion policy of a Process model (PM) when it is deployed. My idea is as follow: Look into PMs there were deployed. Change the data retention to delete after 1 or 0 day  have a list of exceptions to not be updated when these are deployed. To run this new PM for each new deploy How Can I extract the UUID of the deployed PMs and then change their policy.  I did this in the past but with old plugins that are not available anymore (and in other cloud instance). Thanks in advance

Hello, I'm extracting data from the database using the 'Export SQL to Excel' smart service and then using the 'Send file over SFTP' smart service. I'm doing this for 4 different tables but the issue 'java.io.IOException: inputstream is closed' seems to appear only for one of the tables. The issue seems to appear randomly as it usually works correctly.  I found an article that addresses the issue directly so I followed the advice by adding a timer (first 1 min then 3 min) before the send over SFTP but the issue persists at random occurrences. KB-1113 SFTP smart service transfers a blank file to its destination - Appian Knowledge Base - Support - Appian Community What could be the problem? Thanks in advance
