FSCM 9.2 PI 26 - Expense Report No matching buffer error when trying to view attachment

Hi,

We are having this "no matching buffer" randomly on some of expense report (and it keep happening) that when the approver trying to view the attachment on a line, it gives "No matching buffer". After the research found on one of the case

Lines key data shows like this

PS_EX_SHEET_LINE

SHeet ID      Line_nbr

0000926503  3

0000926503  4

0000926503  5

Attachment shows like this. We are having this issue because, Line NBR 1 transaction still exists but should have been deleted when correct parent expense line is deleted. We do not know at this point the scenario this occurs. Could you please check if any solution out there for this issue FSCM 9.2 Beyond PI 26.
