PostSourcing function in a NetSuite Client Script isn’t working as expected

If your PostSourcing function in a NetSuite Client Script isn’t working as expected, here are some tips to troubleshoot and ensure it functions correctly:

1. Check Script Deployment & Record Type

Ensure the script is properly deployed to the correct record type.
Verify that the deployment status is set to “Testing” or “Released”.
Ensure the script applies to the correct role and user.

2. Verify Field Dependencies

PostSourcing triggers when a sourced field changes (i.e., a field sourced from a lookup or related record).
If your field is not sourced, the function won’t trigger.
Example of sourced fields: entity (Customer on Sales Order), item (Items on Transactions).

3. Confirm Field ID Matches

Ensure you’re using the correct field ID in the fieldId parameter of postSourcing event.
Use the developer tools in NetSuite or the log.debug method to confirm the field ID.

4. Add Logs for Debugging

Use console.log or log.debug to check if the function is triggering:

Check logs in Execution Log under Script Deployments.

5. Ensure Script is Applied to Sublist (if applicable)

If working with a sublist, use the correct sublistId in the context.

6. Check for Errors in Console

Open browser console (F12 → Console) and check for any JavaScript errors.

7. Use `context.currentRecord` Correctly

If accessing record data, always use:

8. Ensure Proper Syntax in Client Script Definition

9. Avoid Conflicts with Other Scripts

If multiple scripts are running on the same record, test with only your script enabled.

10. Test in Different Browsers

NetSuite scripts behave differently in Chrome, Edge, and Firefox.
