I see few new fields in tables of tdpur400 and tdpur401 in baan 5c. Maybe they are present for long time. But is there a way to find now, when exactly these fields were added? And is ttadv422 audited by default? If yes, that is one way. Not sure if PMC history can answer this.

Fields being

tdpur400.ragr - Remittance Agreement
tdpur400.cdis.l - Motive
tdpur400.code.l - Delivery Code

tdpur401.tdis.l - Trade Discount
tdpur401.acst.l - Additional Cost
tdpur401.oded.l - Other Permissible deductions
tdpur401.exin.l - Excise Invoice

Some look like localization contents.

Is there any other way. Please help. Thanks in advance.
