Hi sharmadhruv,

To give you a precise answer, we need a bit more detail on how the integration is set up. However, I can point you to the most common reason why this fails.

The Likely Issue: MRVS Data Structure Unlike standard variables, you cannot simply target a variable inside a Multi-row Variable Set (MRVS) directly (e.g., current.variables.mrvs_name.accept_reject = 'true' will not work).

ServiceNow stores the entire Multi-row Set as a JSON String. To update it via any integration (Scripted REST API, Flow Designer, or Business Rule), you must follow this pattern:

  1. Get the full JSON string from the MRVS.

  2. Parse it into a JavaScript Array.

  3. Find the specific row index you want to update.

  4. Update the object.

  5. Stringify it back to JSON and save.

Example Script (Server-side): Assuming your integration triggers a script on the RITM:

 
// 1. Get the current JSON string from the Multi-row Variable Set internal name
var mrvsString = current.variables.your_mrvs_internal_name.toString();
var mrvsArray = [];

if (mrvsString) {
    // 2. Parse into Object
    mrvsArray = JSON.parse(mrvsString);
}

// 3. Logic to find the correct row (e.g., updating the first row, or finding by ID)
// Here we are updating ALL rows, but you can add an 'if' condition
for (var i = 0; i < mrvsArray.length; i++) {
    // 4. Update the variable value
    mrvsArray[i].accept_reject = 'Accept'; // Use the variable name, not label
}

// 5. Stringify back and save
current.variables.your_mrvs_internal_name = JSON.stringify(mrvsArray);
current.update();

If this doesn't help, please clarify:

  1. How does GitHub trigger ServiceNow? (Webhook to Scripted REST API? Flow Designer Action?)

  2. How do you identify which row in the multi-row set needs to be updated?

If this response helps you solve the issue, please mark it as Accepted Solution.
