Field help (SOHBPCPYR) 

The Pay-by BP is initialized by default by the pay-by BP associated with the sold-to customer in the latter's record. It is possible to modify the pay-by BP if necessary. From this field, it is possible to select a BP or access BP management by tunnel if the user's authorizations allow it.

Special features linked to the inter-company option: In the case of an inter-company order automatically generated from a purchase order, the pay-by BP corresponds to the customer associated with the invoicing site entered in the purchase order. This information is not modifiable in this context.
