Hi Naveen
I believe your accounting entries are as below
At the time of PGI
Stock in Transit Dr
To Stock FG
At the time of billing
COGS Dr
Customer A/c Dr
To Stock in Transit
To revenue
I believe Stock in Transit is a B/s Account and COGS is a P&L Account. Can you check if COGS Account in this case has been created as a P&L and Cost element as well or not? If not, the entries will not flow into COPA. Ideally in this scenario, it should be created as a cost element with category as 12. In case the cost element category is 1, make sure you maintain the cost element in OKB9 with Proft Segment ticked as well for each of your company codes.
