“General Journal Account Entry” does not include the UUID field, known as CFDIUUID_MX.

Issue Context: In Dynamics 365 Finance and Operations (D365FO), when importing general journal lines using “Data Management” or “Excel Add-Ins,” it has been identified that the UUID field (CFDIUUID_MX) —required by Microsoft’s Mexican localization— is not available in the standard data entity General Journal Account Entry. Although this field exists in the journal lines interface, it is not exposed for mass import/export operations.

Operational Impact:

• Affects multiple Mexican companies.
• The absence of the field prevents compliance with Mexican fiscal requirements.

Key Findings:

• The UUID field appears in the journal lines screen for Mexican users but is not available in the data entity for import.
• The “Insert Columns” feature allows manual addition of the field, but this is not viable for bulk operations.
• It has been confirmed that the CFDIUUID_MX field is missing from both the import template and the field mapping in the entity.

Expected Outcome:

• Modify the General Journal Account Entry entity to include the UUID field (CFDIUUID_MX).
• Ensure it is available for both data import and export actions.
• Make the field visible in the Excel Add-In template by default.
