dual reporting -urgent

Hi

Iam using T_Code:PO13 for creating relationship between

Position to Position.

I am using A/002(reports to) to one-to-one Position relationship.

but when I use same Position number it does not allow or deleting overlapping records if i use A/002 Type relationship.

Iam using A/005(Subordinate to ) for the same Position who reports to two different Positions.

I am using two relationship types i.e.A/002 and A/005 to relate to two different Positions.

Please advice.

Thanks

Archana
