By default, when fetching work orders, j5 uses the most permissive settings for SHOW_OPTIONS_WITH_FROM_DATE and SHOW_OPTIONS_WITH_TO_DATE to prevent any variance in these from the synchronization windows from missing work orders. This can cause performance issues with very large SAP installations. The option Restrict Work Order FROM and TO Date tightens these filters to set
SHOW_OPTIONS_WITH_FROM_DATE to the start of the period being fetched, and
SHOW_OPTIONS_WITH_TO_DATE to the current day. There is a risk that this will cause valid work orders to be filtered out.
