BAPI / FM to update the product hierarchy(Account Assignmet) in sales order

[lpodile]

I am looking for some BAPI/FM to update the Product Hierarchy in the account assignment (CO-PA). I have gone through the existing similar questions but no clue...I know the least option is going for batch input. But I am still hoping there must be something in standard to take care of this update. So just posting again for the same. If anyone have answer, pls respond. Thank you in advance.

The solution I followed for this is as followed

1. Implement the Table lookup in KEDR for copying the PRODH from VBAP to CO-PA

2. Now we can use the BAPI to change the VBAP-PRODH. This will be copied into CO-PA ( Account Assignment) based on step 1 configuration.
