Hi Faisal.
Thank you for your reply.
Yes, I was added additional set types to category and loaded again (via initial and delta) several times.
After that some fields (see new screenshots) was successfully bounded.
But I can't find my required field'Inventory n.'in CRM UI after load because there's no bounded field for this.
I believe also what this field loaded to CRM but I can't find (via SAP GUI) where required field located.
Therefore I think about some method for link external field in ERP to local field in CRM..
