There is an extension IDOC already defined for Orders which has one Z*segment type defined. The release flag is not set on this segment . I would like to add another field to this segment. I added the field in WE31(Z1EDk02-->Z2EDK02) but when I checked in Se11, the field was not added in Z1EDK02 structure. It was avl only in Z2EDK02. So I manually added the field in SE11. Could you please advise if this is correct process or should I create a new segment type ? Thanks in advance for your help!
