Hello Raman,
1. I've deleted DataSource because after activating its Append Structure, it ended with error message and it was not going anywhere.
2. I've went to LBWE and found that DataSource is Inactive: see below screen shot:
3. On ECC side Table: ROOSOURCE found that Object version is D: See below screen shot:
After error it was not going anywhere that's I had to delete it from RSA6 and am unable to activate it again.
Many Thanks!!!
