Summary:

We have created security roles for every legal entity in our organization, which will restrict access to accounting segments, we want to know whether it is possible to bring role wise restriction. For e.g. users of Company A has access to LOB SEGMENT 0999 but users of Company B does not have access to same, but users of company B need the access to segment 0999 for entering intercompany transactions. Is it possible to do the same, without giving them the access to make entries in general ledger module, they need to make entries in intercompany module only
