Need information on Requisition BU, Default Ship to Location and Sold To Legal Entity while creating PO

Content

Hi Team,

Have a query regarding the creation of PO described below:

In the Create Order screen, on selecting the Requisition BU, Default Ship to Location and Sold To Legal Entity is populated.

If the Default Ship To Location field is changed then in Sold TO Legal Entity field updated the values in LOV.

Need to understand which table stores the linkage between these three - Requisition BU, Default Ship to Location and Sold To Legal Entity ?

Thanks
