BBP_BS_GROUP_BE for new document type and number range
I am working on Classic scenario in SRM and currently have used the above BADI to use a different document type and number range when creating the PO in the backend system. It all works fine. The only thing is I noticed that the BE_DOC_TYPE field in the shopping cart is still reflected as 'EC' even though the PO created in ECC is for example EC1. My question: Is this standard SRM? If so, is it common to leave this field as it is or is it advisable for us to change the document type to EC1 as well? Also, is there any implication in standard SRM reporting and downstream processes that you are aware of?
Appreciate any advice on the above.
