How do we restrict the Company BSV not to be used to enter sub-ledger transactions.

Summary:

There is 1 Legal Entity(LE1), 1 BU and 1 Primary Ledger. Company BSV (e.g. Company 123) is assigned to LE1  

The requirement from the client is that there is another company BSV (e.g. Company 456) which is not related to LE1,

The client requirement is that Fusion General Ledger must provide an ability to process journals for BSV Company 456 in the primary ledger (only for General Ledger) and this BSV is not required to be available for sub-ledger transactions like Receivables or Payables Invoice, Credit memo & debit memo etc.

In order to address client requirement BSV Company 456 is assigned to the Primary Ledger in Assign Balancing Segment Values to Ledger page. The Outcome of this setup is that we are able to enter journal for Company segment 456 as expected.
