Field help (VATVLYSTR) 

Date ranges are only active for Detail VAT box types.

For reprinting and tracking changes, enter the Validity start date and Validity end date of the current combination of values.

The validity end date must be greater than the validity start date. Dates are not mandatory.

The combination with a Detail VAT box type is only taken into account if all or part of its validity period is included within the date range of the Belgian / French VAT declaration implementation.

After you enter the validity end date, the system controls the singularity of the entered combination for the current box code. For a Declaration + Company VAT setup, in a given Detail VAT box, you cannot enter more than one combination of the same value for the VAT management, Tax allocation, Tax code, Entry type, Validity start date, and Validity end date fields.

These fields can contain multiple combinations of identical values as long as these combinations are referenced in distinct boxes.

Note: For two identical combination lines (excluding dates), the validity dates on the Detail tab are not controlled and can partly or fully overlap, whether or not the combinations belong to a VAT box.

During the French or Belgian VAT extraction process, an entry line with a date included in the overlapping period will be taken into account in each considered VAT combination.

Note: This control is enforced differently according to the kind of VAT function that is run. When the Belgian VAT or French VAT on debit is run, these validity dates are checked against the starting declaration date and the ending declaration date indicated in the process. On the other hand, when the French VAT on payment is run, these validity dates are checked against the Due date until value: A box is valid and usable if its start date and end date include this due date.

This type of setup is used to manage new VAT boxes corresponding to part of an already existing VAT box. Check the consistency of dates to avoid redundancy.
