Hello Krishna,
DSM = My solution Manager (so don't be pertub by this).
You should do the following :
1. In your solution manager --> Start the TCODE LMDB
2. Then select the name of your system --> Edit
3. Check if the system number is correct otherwise correct it
Then regenerate a new XML (via the MOPZ) and restart from scratch the SUM.
At least this was solving my issue.
