Hi Szymon. I was quite busy. Letme share what i found:
in KE4J, the system dont allow add a Costing Key for 'Parallel Cost of Goods Manufactured' (valuation 5) Only allow valuation 0 Legal or 1 Group. So I cant set the 2nd key.
The program is hard coded
Also, dont allow set a 'plan version'.. because my plan version '0ML' is assigned to 'Parallell Cost of Goods Manufactured' in the valuation profile.
Any other idea ?
Arturo.
