All VAT reports are enhanced by the functionality to exclude all documents already reported by a previous run.

In the beginning of April, the VAT reporting for the first quarter is prepared and the VAT summary report RFUMSV00 and the tax invoice summary reports are executed.
In the beginning of July, the VAT reporting for the second quarter is done. All documents posted during the period April to June must be reported. However, the documents posted in the first quarter of the year but not yet reported to the tax authorities must also be selected.
It is now possible to mark all the documents selected by a VAT report by activating the check box Update tax item date/time. If this check box is activated in the execution of the report RFUMSV49 in April, all selected documents are time stamped and the report RFUMSV49 can be executed again in July. By selecting all documents posted since the start of the year, the report only displays those documents not time-stamped during a previous run of the report.

If the summary output VAT is created based on issued tax invoices, i.e. the report RFUMSV45 is used to create the summary list of output VAT and the option Update tax item date/time is activated in the report RFUMSV49, then the issued tax invoices are marked with a time stamp. Or more in details: the FI-Invoices which belong to tax invoices are marked with a time stamp. The tax invoice in the system which is also a normal FI-document does not have a time stamp field itself.
The time stamp can be used for two different purposes. The first purpose is to rerun a VAT report and exclude the documents already reported. For this option, mark the flag Excluding reported data.
The second purpose is to reproduce the result of a previous report. In this case, the report would select only those documents with a certain time stamp. For this option, enter the desired execution date and the time of the VAT report in the fields Date of tax report and Time of tax report in the selection screen of any of the VAT reports. The selected documents are then checked against the other selection criteria entered on the selection screen of the report.
