EMEA VAT: Pre Reporting Concurrent Program

Prior to running the EMEA VAT: Selection process, the EMEA VAT: Pre Reporting program needs to be run. There are 4 parameters:

1. Reporting level: Ledger
2. Ledger: Ledger name
3. Balancing segment (is greyed out and if you try to enter it errors out)
4. Last Reported Period

The question I have is with the 4th parameter. According to the guide Oracle Financials for Europe User Guide, "The EMEA VAT: Pre Reporting Process only needs to be run the first time you run reports in Oracle Financials for Europe." However, on the parameter it comments, "The last period in which EMEA VAT reports were submitted."
