Credit Checking for multiple Legal Entities.

Dear All,

We are working with a prospect customer and they have a unique credit checking requirement.

This Client has three legal entities and each customer of cleint deals with all the leagal entities but have a one bank gurantee for all the companies. Now prospect customer wanted to performe credit checking as an whole. For an example,

     Legal Entity A -----> Operating Unit  A

     Legal Entity B -----> Operating Unit  B

     Legal Entity C -----> Operating Unit C

     Customer Name: Dummy_Cust

     Customer Site: Dummy _Site (Which has access to the all the operating units A,B,C)

My cleint going generate separate invoices for the each and every leagal entity but need to check whole credit of the customer before booking the sales order.
