I am trying to update my customer payment record with the journal id but I am receiving this error "Unable to find a matching line for sublist apply with key: [doc,line]." why is this the case ?

AI generated answer (using internal Slack threads):

The error message "Unable to find a matching line for sublist apply with key: [doc,line]" typically indicates that NetSuite is unable to find a matching line in the 'apply' sublist for the specified 'doc' and 'line' values. This could be due to several reasons: 1. The 'doc' value you're using does not correspond to a valid transaction in the 'apply' sublist. Make sure that the 'doc' value corresponds to the internal ID of a valid transaction that can be applied to the customer payment. 2. The 'line' value you're using does not correspond to a valid line number in the 'apply' sublist. Ensure that the 'line' value corresponds to a valid line number in the 'apply' sublist. 3. The transaction you're trying to apply does not match the exact amount of the payment you're trying to upload. If the payment amount does not match the exact amount of the transaction, NetSuite will not be able to find a matching line in the 'apply' sublist. 4. There might be a rogue User Event (UE) script that is interfering with your code. Check your scripts to ensure that there are no conflicts. 5. If you're working with a large number of lines in the 'apply' sublist, there might be a limit issue. However, the limit for lines is usually higher than 3271 lines, so this is less likely to be the issue. Remember to set the account field after applying the journal, as it seems that checking the 'apply' field on the line unsets it. This behavior is different from the UI, which might cause confusion. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
