Hello Sanjay,
Hope you are facing problem with your userId position assignment. please edit the ORg.struture(T.Code: PPOMA_BBP) and drag your userID to some other Org Unit + SAVE and Once saved the Org structure , again drag back to your original Unit + SAVE. It may works.
Or
Please check the Extended attributes tab for Unit properly assigned or not.
All the best Sanjay..
