Hello,
Not sure to understant your requirement.
A few comments :
You created table view for one order object. Therefore, CRMD_ORDERADM_H is not extended, for this structure can only contain extension of fields, not a table one (seems logical,no ?). So I am not sure about your inquiry : "I want to add these fields into CRMD_ORDERADM_H table". Can you elaborate more ?
As per adding append structure into CRMD_ORDERADM_H directly, I strongly advise you not to do so : use AET to add custom fields into CRMD_ORDERADM_H, and the system will automatically manage everything for you.
Best regards,
Sylvain AGUETTAZ
