Does TWE Organization Code - Thatwe create as a descriptive flex field used anywhere else except for

We are in a process of setting up our ADP Taxwrae adapter in R12 Account Receivable application and have the following questions:

 - As a part of R12 Taxware adpter integration we need to create a new descrptive field called "TWE Organization Code". then we need to enter our Oracle OrgID in this field. My questions is as follows:

        in our current R12 application the value of our Organization id that is used by our GL, AP, PO, FA, INV and rest of our application is using the value of "101".

        in our current ADP Taxware enterprise application we have our organization code as "13-655558".
