Introduction :
As many posts/blogs are extensively available online for the above subject, the purpose of this post is to highlight a few key points, differences & relv. SAP Notes consolidated.- on a high level.
The basic point to be kept in mind is that, STD SAP does NOT permit the flow/default of Payment Card # from the CMR into an SO. They have to be entered manually by an user at SO level.
The above is applicable for S/4 HANA systems too.
For copying the payment card # automatically from the CMR into the SO, a custom code is to be implemented at USEREXIT_MOVE_FIELD_TO_VBAK ( Include: MV45AFZZ)
