Hi Sam,
Sorry, I rephrase my question :
YY = All my scope Co. Codes
XX = A unique Co.codes which is in charge of the payment method C and D (interco Payments) on behalf of all the YY Co.Codes
All Co.codes have payment method – A,B,C,D
All Co.codes should be able to use payment method – A,B,C,D
For the payment methods C& D, XX must be the paying entities
For the payment methods A& B, YY must be the paying entities
Thank you very much for your help
Regards
Cédric
