Requirement to restrict intercompany journals posting

Hi,

  We have a requirement wherein we use a single ledger- wherein we have multiple balancing segments which takes care of multiple branches. One of the segments in the COA is the intercompany segment which we use for recording the intercompany transactions.

Whenever the intercompany transactions get transferred onto GL we need to have a control wherein the journal entries(which includes the intercompany transactions) pertaining to one branch should be postable by one branch and the journal entries pertaining to another branch(including the intercompany entries) should be postable by another branch - is this possible?

The example has been cited below
