Sometimes we do not have enough information in a XML that has failed and is hard to track the root cause, even in the trace option under SXMB_MONI or SXI_MONITOR the information is not enough. In this case is required to debug. For that we need to get the service interface from XML in error and start the debug from SPROXY.
For one case in special that I was working, the issue was happening when a supplier was being replicated from ECC to SUS by BD14 transaction. I have debugged and I found the error “AM 215: Region “X” is not defined for country “X”.
In the XML this region was missing. This information must be maintained to Supplier in the ECC side.
In the SUS side the region is maintained in the table T005S. In order to further information please check the SAP KBA 2015043.
