CALL CUSTOMER-FUNCTION '001' Exit EXIT_SAPLVV01_001 Include ZXVSVU01

Question

Hi,
I need to develop the Idoc type extension for DEBMAS06.
Following is done:-
I have added the segments and added the extended Idoc type to message type.
I have added the function module, message type, Basic Idoc type and Ext Idoc type.
I have created the project also.
Now I need to write the code in the include ZXVSVU01 of the Exit EXIT_SAPLVV01_001.
Do I need to write the code for the extended segment data? How should I refer to the global data?
While debugging control does not go into the Z include, why?
The function module is MASTERIDOC_CREATE_DEBMAS.
I will appreciate if help can be extended in understanding about it.
Thanks,
Azhar.

Hi,
     1)
/nWE31
Here will create the segments for extend our idocs.
Example: 'ZDUMMY'
-> Write a short description and field name.
-> Data element = CHAR1 (will create a new field in the idoc with 1 character extension)
-> Save (developer permissions needed)
2)
/nWE30
-> At development object select 'extension'
-> Write a name for object name (8 char extension). For MATMAS IDOC extension i create ZMATEX01. Click on 'create' button.
-> Now we will select the IDOC link. Select 'create new', and link to a basic type (MATMAS05 in our example). Don't forget to write a description (will be usefull in the future for identificate correspondances).
-> Select IDOC substructure where wich will be extended. Click on header and 'create segment' (you can paste from clipboard with 'insert' button).
-> Select ZDUMMY segment created before.
-> Save and fill package and transport order for this modification.
-> Release segment from toolbar (Utilities)
/nWE82
Add Message Type (MATMAS), Basic Type (MATMAS05), Extension (ZMATEX01) and Release.
Finish
All it's done! So now you can use your new IDOC. For SAP XI, must import again to your integration scenario. Check ZDUMMY field at the segment you have selected.
