FactoryMaster: The launch date from raised PO's and start date from the list of suggested PO's do not match

When I run the MRP, I use the export option to Excel, so that we can then use these for Forecasting to our suppliers, and also for our trackers. However, the launch dates on the Exports differ from the launch dates that the FM MRP Screen shows.
It appears, that our system is set up for a 5 day working week, and this is reflected in what the FM Screen will show, but on the exports into Excel, the code has not taken this into account, and runs on a 7 day production week.
​
For example, a part that has a Lead Time of 40 days, if it is required on the 01/04/2022, then the launch date of the PO based on a 5 day working and supplier week, is the 04/02/2022.
The export says that the launch date of the PO, should be the 20/02/2022 - which is 2 weeks why of the proper launch date, as it is counting it as a 7 day week.
​
The functionality has been enhanced in FactoryMaster version 20.12.13 or 20.13.03 or above. Please upgrade.
