The Error is about Posted No. Series gap happened if I deleted a line in the Payment Journal (attached a screenshot of the error).
the steps that lead to this error like this:
1. make records of payments and sending it to approval (selected Journal Lines).
2. if one is rejected and removed.
3. trying to post the journal (error accord).
workaround.
before step 3:
1. use the function renumber document number (marked in the screenshot).
this will reassign the document no for the records, but the approval is gone and need to resend to approval again.
so, this is the problem I am facing.
