Hello Juan, Please take a look at the documentation of BTE 1140. The purpose of this BTE is to deactivate some funtions (for example , 'PARK' or 'POST') You can take a look at the following wiki page
http://wiki.scn.sap.com/wiki/display/ERPFI/Example+for+BTE+00001140
In my opinion you are using this BTE for something else. Could you please try to clarify your requirement in more detail then maybe we will be able to help you further.
Best Regards Zidane
