New Branch in S4hana

[moal85]

Dear All,

we want to create a new branch in S4HANA without using a new company code and a specific gl accounts.

In order to have this detail we decided to use the Business Area as a driver, in this way we are able to have a FS, specific for the new branch separate to the main company code.

The problem is that the Business Area is not retrieved in all line items for all the documents posted, also in case of automatic flow like the revaluation or the automatic payment F110.

How we can derive automatically this information in all line items for all accounting records ?

Furthermore is the use of the business area correct or it woul be preferable to use segments ?

Thanks
