AI generated answer (using internal Slack threads):

The error message you're encountering, "*Unable to find a matching line for sublist apply with key: [doc,line] and value: [523085,0]*", typically occurs when NetSuite is unable to find a matching line in the sublist for the provided key and value. In your case, it seems like the issue might be related to the line number. In NetSuite, line numbers start from 1, not 0. So if you're trying to apply a payment to the first line of an invoice, the line number should be 1, not 0. You can verify this by checking the invoice in the NetSuite UI. Add

&xml=T

to the end of the URL to dump the record and check the line numbers. If the line number in the dump is 1, then that's likely the issue. To fix this, you should update your request to use the correct line number. For example, instead of

<ns8:line xsi:type="xsd:long">0</ns8:line>

, you should use

<ns8:line xsi:type="xsd:long">1</ns8:line>

. If the issue persists even after correcting the line number, it might be due to some other issue. In that case, you might want to initialize the customer payment and only set the fields that you want to change.
