Business Need

Business Central currently allows Purchase Orders containing blocked VAT Posting Setup combinations to be created, released, submitted for approval, and approved without warning. Validation occurs only during posting, causing process interruptions and requiring approved documents to be reopened and corrected.

Suggested Enhancement

Introduce validation of blocked VAT Posting Setup combinations before posting, such as:

• During Purchase Order line entry.
• During document release.
• Before approval submission.
• During approval processing.

Current Behavior

Users can select a blocked VAT Posting Setup combination on Purchase Order lines. No validation is performed until posting, where the system returns an error indicating that the VAT Posting Setup combination is blocked.

Expected Behavior

Business Central should provide an earlier warning or validation error when a blocked VAT Posting Setup combination is used, preventing documents that cannot be posted from progressing through the business process.

Business Impact

• Prevents documents from reaching approval with invalid posting setups.
• Reduces rework and administrative overhead.
• Avoids reopening and reapproving documents.
• Improves user experience and process efficiency.
• Identifies configuration issues earlier in the document lifecycle.

Scenario

1. VAT Posting Setup combination is marked as Blocked.
2. User creates a Purchase Order and selects the blocked combination.
3. Document is released and approved successfully.
4. Posting fails because the VAT Posting Setup combination is blocked.
5. User must reopen, correct, and potentially resubmit the document for approval.

Requested Outcome

Provide configurable or standard validation of blocked VAT Posting Setup combinations before posting to prevent invalid documents from progressing through approval workflows.
