Fields in Access sequence are not getting populated

Hi Friends,

    We are working in a STO scenario wherein the billing is created with reference to Outbound delivery. In the STO based pricing condition i.e. VKP0 if the access sequence table exists for fields Supplying plant and receiving plant, please let me know how this data will be transferred to Billing pricing condition VKP0 having the same access sequence table. In my case the supplying plant is getting populated however the receiving plant is not getting populated in Billing.

I have checked the copy controls also from Delivery document to billing document. Basically I want to find out how the data will get transferred from KOMK-RESWK and KOMP-WERKS which has been maintained in MM Access sequence table to KOMK-RESWK and KOMP-WERKS in SD Access sequence table.

Thanks in advance.
