Question

=======

I am in need to EXCLUDE a specific G/L account from being selected, from the drop down list, when executing FB60 (Enter Vendor Invoice) to create a new vendor invoice ?

1) Is this doable ?

2) Could this be done programmatically (ABAP team) ?

3) Could this be done at Security Role level (Basis & Security ABAP team) by using the field BRGRU of the F_BKPF_BES Authorization Object ?

I have received so far very useful remarks from Paul01, Mauri, SAPFICO, Mohammed Zia, and Sudhaker Gogula.

THANK YOU ALL!

Here are my answers to each one:

To Mauri:

========

YES, we define the authorization Group via FS00 --> Control data, which means the relevant authorization object will be F_BKPF_BES.

As I said earlier, the corresponding field will be BRGRU and and not BEGRU.

Then the question is, WHICIH AUTHORIZATION GROUP DO I SET, for the value of BRGRU, there are thousands !!

To Mohammed

============

How do I "block that GL account for postings in GL master record" ??

Programmatically (ABAP) or via Security Role(s) ?

To Sudhaker

=========

Could you please elaborate the solution USE VALIDATION.

I am not familiar with that!

Is it something that ABAPers do ?

Could something be done by using Authorization Groups // Authorization Objects ?
