Hi Naveen
I had a similar issue which was caused by some programming error in MRS. No matter whether you are using MRS or not, check whether the following notes are applicable or not:
1731512 - MRS / PM Split Integration not working (This note refers to the following three notes):
- 1108105 - IW32: Empty line appears in requirement assigment tab
- 1298656 - Detailed workforce planning data not saved correctly
- 1360307 - Dump due to split deletion
Otherwise, as noted you can always write to OSS.
Regards
