Currently, the records in the "VAT Business Posting Group" and "VAT Posting Setup" tables are valid for the entire application and, a priori, it is possible to establish configurations in the Customer and Vendor tables configured by the Sales and Purchasing managers respectively.

However, the Finance department may have previously decided that they are not all applicable in Sales or Purchases respectively, not defining the Accounts necessary to register in either of these two modules.

This causes Errors at the end in the registry to the operational users due to a bad configuration made by their supervisors.

The idea would be to define a new field "Applies to" with the following possible values:
- Both (default value)
- Blocked (to block old invalid records)
- Sales only
- Purchases only

With this new field, the table-level TableRelation (and Lookups) of the existing fields in the Customer, Vendor cards and its respectively Templates could now be filtered to show only the valid records in each module and the common to both.

And the same improvement with the TableRelation of those same existing fields in the Headers and Lines of Sales and Purchases.

The same idea would also apply to the separation of configurations in other tables such as the following:

- "Gen. Business Posting Group"
- "General Posting Setup"
- "Payment Terms"
- "Payment Method"
- "Payment Day"
- "Non-Payment Period"
