Use this function to refresh calculated earliest operation start dates to reflect changes to component availability.

The FDMA is the "First Date of Material Availability". This is the date calculated for each component of a work order when component availability can cover, in full, the required quantity. The earliest operation start date is calculated from the component FDMA. For each operation on the work order this is the date when the full quantity of each component required for the operation is available. Frequently, however, stock movements affect the calculated (suggested) First Date of Material Availability. A purchase receipt might be delayed in transit, for example, thereby affecting the availability of the material required for a work order; a defect might be detected in a component on the shop floor resulting in a break to the processing whilst a replacement component is sourced.

The FDMA is one (of several) constraints Production Scheduler (FUNPSSCH) can use in the optimization of the operations. Production Scheduler, however, does not automatically recognize changes to work order component availability. You should therefore run this function frequently so that Production Scheduler observes changes in material availability in subsequent optimizations.

 You are advised to run this function frequently and especially after any known change to a component availability date. It is the planner's decision how often, for which work orders, and when this should happen.

 You can integrate this function in the batch server so the FDMA recalculation starts regularly. For example, you might choose to run this function overnight or at a regular time based on updated trackings, receipts or MRP calculations.

Production Scheduler is only available for on-premises instances of Sage X3. If the POPS - Production Scheduler activity code is clear and the GFS - Finite scheduler activity code is selected you are using the generic Finite scheduler interface to Sage X3 Web Scheduling or to a web scheduling solution developed by an ISV (independent software vendor) for either cloud or on-premises solutions. You must use the Finite scheduler > Recalculate work order FDMA function (FUNGFSFDMAUP) instead of this function.

Screen management

The Recalculate work order FDMA function displays two selection screens:

  • An initial screen into which you enter your selection (or filtering) criteria;
  • A validation screen in which you confirm the work orders to be refreshed.

A log file displays the results of the run.

Entry screen

Type in, or select the site at which the work orders are to be refreshed, then select the work orders statuses to be included in the run.

A number of ranges are displayed.

  • To select all work orders to the selected stage of the production cycle, leave all the fields blank.
  • To select specific work orders to the selected stage of the production cycle, type in the required ranges. Leave the first field blank to include the lowest value or the second field blank to include the highest value.

You can optionally select the work orders by applying a calculation formula.

Tab Selection screen

You use this tab to confirm the details of the work orders to be refreshed.

To exclude a specific work order, either leave the check box clear or click Delete from the Actions icon.

A log file displays the results of the run.
