What is the purpose of Internal Ship and Debit request?

Hi All,

My company is a distributor of goods which runs various promotional events and offers for retailers and chains. We are executing Channel Revenue Management R12.2.5

We have a requirement where an Accrual offer is being created for the end customer. Part of the Accrual offer is being funded by the Supplier and part of it would be funded by the Company themselves. e.g. A promotional program for Item A can be funded by either the supplier or the Company

We were planning to create a supplier Ship and Debit for the supplier funded part and Internal Ship and Debit for the Company funded part.
