I was getting below Idoc error with status 51 "filed Supplying Country is a required field"
After investigating i found that in the Segment E1EDK29 field TEXT1 and TEXT2 was missing which is actual field for Supplying country which can seen in above screenshot last field. We have only maintained few countries in Idoc structure and this country Japan and Malysia is not maintained and thats why Idoc was failing. I have reprocessed it manually via BD87 and entered the field supplying country as MY and Idoc is passed. As you can see both filed were also addred in the end.
Now I want to know where can i maintain other countries so next time Idoc will not fail. My question is only where to maintain this countries in Idoc Structure with step by step as i did lot of investigation but could not find the exact answer.
