I am trying to transfer a newly created customer from ECC to GTS. When transferring the customer I get a message saying "All selected partners (1) have been processed successfully", but when I see the log in ECC system, I get the following message "Logical (feeder) system cannot be determined Message no. /SAPSLL/CORE_LEG307".
I tried transferring the documents and Vendors, which is happening perfectly.
FYI: Customers have been transferred successfully earlier. Please let me know, if any of the changes could have affected this transfer.
