This is a call of user-exit.

You have to find the ZX_____ Abap which is called to put your own code.

How do u find it ?

Hi,

This is one of the FM's for the user exit.

Here you will be able to use the values which you are passing to the FM to change the structure XVBAK and the other tables which you passing.

The coding that you will do will be inside the FM

HI Ramu,

Check

http://www.geocities.com/SiliconValley/Campus/6345/call_cus.htm

Variant 6

CALL CUSTOMER-FUNCTION func.

Additions

The same as for CALL FUNCTION func.

Effect

Calls the function module func . func must be a 3-character literal (e.g. '001')

In line with SAP's enhancement concept, function modules are delivered empty and must be implemented by the customer (the transactions used for this are SMOD at SAP and CMOD at the customer's).

The interface and call location are both defined by SAP.

Note

The customer can use Transaction CMOD to activate the function module. The final name of the function module is compiled from EXIT_ , the name of the module pool where the function module is called, and the name func . For example, the statement " CALL CUSTOMER-FUNCTION '001' " in the module pool SAPMS38M calls the function module EXIT_SAPMS38M_001.

Santosh

Hi,

This is a Function module which is called in any mainprogram of any transaction and is used is a call to an USER EXIT.

Exporting means values that you pass to the Function Module from the Program which calls the function module. These values are received in the Import parameters of the function module.

Tables is used to pass values of an internal table from the Program that calls the Function Module.

Changing is used to pass values from the Program that calls the Function Module and some manipulations could be done inside the Function Module and the values of these parameters (Changing parameters) are modified and and can be recieved in the main program.

The code would be written in some user exit and could be found on doubleclicking on '001' which would b ean include starting with 'ZX......' in a Function Module starting with 'EXIT_....._001'.

Moreover this is not an unique function module name.

Hope this would be helpful.

Thanks,

Prashanth
