How to create hierarchy in BPC NW 7.0 for a child which has two parents ?

Question

I need to create a hierarchy in which some of the children have 2 parents (only some, not all of them). I tried using two columns - parenth1, parenth2. but it would not permit me since I cannot leave p2 blank for those children which have only one parent. If I try putting in p1 and p2 same for such children, then I get an error saying duplicate.
Please advice.

How do you expect this roll-up to work numerically? Do you want ACCOUNT1 to be counted twice at the Child level, or do you expect it to cancel out (like it would in a BW hierarchy)?
I'm curious about the structure of your P&L that leads you to want this type of display. I have seen a lot of P&Ls and I've seen this requirement a few times, but usually you can meet it by recognizing that the P&L hierarchy and the reporting structure are separate. In this case we can often re-factor a single reporting structure with this type of roll-up into two or more separate P&L hierarchies, or we can use calculated accounts to provide for a more flexible reporting structure.
In any case, the scenario you describe is not possible using a single account and a single hierarchy in BPC. You can do one of the following (I'm probably missing an option):
1. Use two hierarchies or more hierarchies, to model alternative roll-ups of the base accounts into your different P&L formats.
2. Use a single hierarchy and another account and a script logic to copy the value of ACCOUNT1 to the new account.
3. Use a formula account to automatically copy values to a different spot in the existing hierarchy (will not roll-up)
