Hi Deepak,
You should check the planning hierarchy in the TC MC62 for the your info structure to see it is maintained completely in the lowest level.
Please also check the table PGAN for GSTRU <info structure>. If there is an entry with PLOBO = PLOBU. You have to regenerate the planning hierarchy (note 920027).
Notes 1709221, 1748455, 1770420, 1777429 and 1783628 are possible correction of the inconsistent.
I hope this could helpful.
Regards, Gordon
