SAP TPM Rebate Settlement

Hi,

I'm trying to settle TPM Rebate in ECC, but I'm unable to do that.

I create a promotion and add a trade spend with rebate discount method; after I release the promo and the agreement, so I can see in ECC the agreement itself.

Now what shall i do? In VBO2 transaction I open the agreement, but even if I use Pay, or Manual Accrual, or Final Settlement, the value remains 0.

If I save a Sales Order is created, then, after inserting some quantities, I try to create a billing document (tcode VF01), but when I save it says to me that are some error on price list.

Can  you help me?

Thanks and Regards
