Customers Group structure includes many companies e.g. 20 companies in one or many countries. Intercompany transactions need main account at least for IC accounts receivables/payables, sales, purchases. In this scenario with current standard functionalities customer would need to setup many intercompany main accounts. Worst case this might mean many hundred intercompany main accounts. We have not done this but created just few intercompany main accounts and use with this one dimension to separate transactions inside main account. So we have dimension with values of legal entity e.g. in contoso USMF, USSI etc. We would like to have this dimension option to be available in needed intercompany functionalities in AX/Operations e.g. creating intercompany invoices (customer/vendor) and in adjustment. We have faced modification needs in Project accounting but this concerns many other modules too.
