How can we derive the Cost Center segment in the COGS account based on the Sales Order Business Unit

We have a customer requirement to map the Sales Order Business Unit (BU) to a specific segment in the COGS account—particularly to select the correct Cost Center based on the selling BU.

The challenge is that the only available source in the Shipping process (used in Cost Accounting) is a different BU—typically the Shipping BU, not the Selling BU—so we cannot directly map it using existing sources in Subledger Accounting (SLA).

In Receivables (AR), the Cost Center is derived correctly based on the selling BU. The customer expects the same logic for the COGS account in Cost Management.
