Partner Determination for Customer Hierarchy

Hai Guys,

I have created a Customer Hierarchy and have enabled it eligible for rebate. I had assigned few individual customer to that hierarchy.

In the partners, I entered one of the the customer as the Sold to Party / Payer and Bill to Party.

While settling the rebate for the hierarchy, barring the Bill to Party, the system takes the Hierarchy Node as the Sold to Party / Payer and Ship to Party, making the credit memo settlements impossible.

Can somebody teach me the partner determination for the Customer Hierarchy?

I did search for the same in the forum, but couldn't find much relevant material about this.

Regards,

Maheshwaran. I
