Если Uukrul вы подскажите мне как бороться с этим СТАНДАРТНЫМИ ПУТЯМИ, то ей богу, при случае я вам выставлю пиво.

4. As of Release 4.70, there is a Business Add-In (BADI) with the definition name FEB_BADI that is called immediately before the standard posting in program RFEBBU00. In this case, you can change the procedure of the standard posting or make additional account assignments by changing the tables that are to be transferred to the posting interface (FTPOST, FTCLEAR). To do this, go to the SAP menu and follow the path Tools->ABAP-Workbench->Business Add-ins, create an enhancement that you assign to the FEB_BADI BAdI and then implement the CHANGE_POSTING_DATA method.
When you activate the BAdI, you receive a message, telling you that the active implementation of this BAdI already exists. If you do not use the public sector industry solution, you can deactivate the active BAdI of the IBS_PS area and activate your own implementation.
5. As of Release 3.1I, to change the standard posting you can also write your own function module that is called at the same callup point as the BAdI FEB_BADI (see point 4). For this, you have to register in user exit FEB00001 (see point 1) for the memo record first. To do this, attach a row to table t_febcl with t_febcl-selfd = 'FB' and t_febcl-selvon = 'Z_FEB_1_ZZZZ', if you want to make a change in posting area 1 or with t_febcl-selfd = 'FB' and t_febcl-selvon = 'change Z_FEB_2_ZZZZ', for changes in posting area 2. Z_FEB_1_ZZZZ or Z_FEB_2_ZZZZ are the names of the function modules for the respective areas. Here you can also select other names; however, the name of the module that is called in the area 1 must contain character string FEB_1_ and the same applies for the name of the function module of area 2 - it must contain FEB_2_. The interface of both modules must be the same as the interface of module FEB_2_STO_LASTSCHR2 or FEB_2_IMMO_LASTSCHR.
