Hi All,
I have fixed it. Thanks Dogboy for guiding and helping me find solution for it.
The problem is some corruption happened in GUID level and left me with only option to do complete removal of Planning version 001 in a standard procedure way and recreated again and did all make Initializing the version and did Data copy and it fixed the problem. There is relationship maintained automatically for the 001 version copied from 000 since both in in active model 000.
Regards,
Prem.
