Can a Validation be Added in Sales Order Where BU Should Match With Its Associated Warehouse?

Dear team,

Business is using Order Management and it is set up in a way that warehouse selection is mandatory. There are 3 legal entities that have been implemented in the system and sales orders are created for 3 business units. There is one warehouse for each business unit.
Sometimes, business users select a Warehouse which is different from the Business Unit that they have selected, which makes the sales order a drop-ship one.
Currently, the system is configured for back-to-back sales orders only and not the drop-ship ones and this mismatch in selection of BU and warehouse leads to issues in processing the sales order at later stages.
