Content (required):

One Ledger has multiple Entities assigned to LE. User is creating AP Invoice in Entity 1 and Liability entity is Entity 1. User is trying to select Entity 2, Entity 3 values at distribution level and User validated the invoices.

After accounting system generated Intracompany accounting between Entity 1 and Entity 2 as user selected different Entity at Distribution level.

If user selects Entity1 and user should be able to select only Entity 1 at distribution level. Do we have any setup to meet this requirement. I analyzed the issue all entities under same Legal Entity.
