Hierarchy not getting displayed in BPS top down planning

HI

As per our business requirement we have enhanced planning levels 4MP70000 and 4MP80000 to make it as planning function for four quarters. This is working fine as expected but we are facing issues in hierarchy. When implemented from CRM side we are seeing them as indpendent structures and not as hierarchies. Also the constraint that the sum of child node amounts should not exceed the parent node is not getting implemented. We used the hierarchy variable 4MKTHI01.

Please guide us what could be the issue and any help on this is greatly appreciated.

Thanks.
