The document describes how to create a validation rule in SAP to check that a specific business area is used when posting to a particular company code. It provides steps to 1) maintain a validation using IMG tools to check the business area is "HYD" when the company code is "TATA" and 2) define the validation at the document line item level so it is triggered during posting. Testing a post shows an error is returned if an incorrect business area is entered, demonstrating the validation is working as intended.
