Hello, Emrah.
TPM20 select data from TRACV_ACCITEM view (function module TPM_TRAC_PJ_SELECT)
Even you change Reference in Transaction or Reference in FI Document. This table won't be updated.
Solution: SE11 -> TRACT_DOCUMENT - this table is part of view TRACV_ACCITEM. Find lines you want by DEAL NUMBER table field to edit and use "Change" button (i hope you have all authorization, otherwise ask your ABAP cons).
