Hi experts,

I want to add few fields in segment BANK_CHANGE01/IDOC/E1BP1011_ADDRESS. For this I have created a custom segment with the fields which are needed to add. Now when I proceed with extending idoc in WE30 for the idoc type BANK_CHANGE01, I am getting an error "Action is not possible for generated idoc types". Please help.

Thanks & Regards,

Barnita Mukherjee

Use search tool or read 1579037 - "ACTION IS NOT POSSIBLE FOR GENERATED IDOCTYPES" when Extending IDOCs which suggests extending the BAPI and then generating a new ALE interface via tx BDBG/BDFG.

the OSS note has been removed.


(Was removed recently I suppose) the solution suggested was:

  • Copy the BAPI in user namespace (ZBAPI) and modify it, adding the new fields.
  • Use transaction BDBG to create a new ALE interface; new Idoctype, Inbound/outbound Function Modules and Message will be created.

Hi, naturally there is a reason for the Error but if your goal is only to extend the idoc type:

WE30->EDIT->Cancel release and then extend. If it is not possible then goto WE30 and extend idoc type with the segment naming with a new name or code for it if possible. in this manner you can create several extensions as you want and can manage them: using one or another upon necessity.

Thanks and Regards

we can not cancel release for standard basic type. and we can not create extension for this. Then how can we extend this.


create a new idoc type with same characteristics
