Business Central seems to have a feature that would be good to have in D365 Finance. Allow substitute customer or vendor posting groups on documentsYou can let people choose other customer and vendor posting groups than the default groups when they're working with sales or purchase documents and journals.To allow changes to customer posting groups, choose Allow Multiple Posting Groups on the Sales & Receivable Setup and Service Mgt. Setup pages, and the Purchase & Payables Setup page for vendor posting group changes.On the Customer Posting Groups or Vendor Posting Groups pages, you can specify the posting groups to allow as substitutes by choosing Substitutions. Substitute posting groups can replace the default customer or vendor posting groups specified for a customer or vendor.After you set this up, you can choose from the allowed substitute posting groups and change the customer or vendor posting group when posting sales or purchase documents and journals. The substitute customer or vendor posting groups are copied to posted documents and journals, and payable or receivable G/L entries are posted to the G/L accounts specified for the substitutes.When applying, for example, an invoice and payment that are posted with different customer or vendor posting groups (different G/L accounts), Business Central transfers the amounts between the G/L accounts to balance them.
