GTS Questions for Indirect Materials and Transfer Error

Hello,

I have two GTS questions. One is for indirect materials and second is for help troubleshooting an error. Please see questions below. Greatly appreciate any feedback.

1. I know GTS is not built to manage indirect materials. The only option I have now is to store these materials in ECC so that they can flow to GTS. I am wondering if there are any other standard options to consider for managing indirect materials?

2. I get message “Of 1 selected partner(s), 0 were processed successfully" when trying to transfer a customer and vendor. Basis looked at the issue and didn't find anything wrong with the system connection/communication. Any suggestions? Is there an OSS note?
