Resource requirement outside the resource available time (shift) in constrained plans

Resource Requirement Start Date is outside the resource availability (shift times) in an Enforce Demand Capacity Constrained or Enforce Due Date plan with seemingly no resource constraint


1. Go into the responsibility: Process Engineer

2. Navigate to Process Operations > Activity

3. Check the Breakable checkbox against the resource that is seen as causing the problem. 

4. Go into the responsibility: System Administrator

5. Navigate to Profiles > System Profiles

6. Set the profiles as below:

MSO: Schedule across breaks = Yes
MSO: Schedule simultaneous resources across breaks = Yes
MSO: Respect Activity Contiguity Flag for Process Supplies = No

4. Retest the issue by running the ASCP Standard Collection, complete refresh and the ASCP Plan

5. Migrate the solution as appropriate to other environments.

OPM/ASCP such that multiple recipe capacities are respected (production lines)

1) Establish the Recipe Validity Rule Quantities (Minimum, Maximum and Standard) to be all the same for the quantity that can be made by that recipe. So, for the first recipe, all three quantities can be set to 10500, the second as 3500 and the third as 2600. All of the preferences should be the same (1) initially for testing and then can subsequently be different if you prefer making in one line over another

2) Set up the Inventory > Items > Organization Items > General Planning tab > minimum and maximum quantities to the smallest and largest recipe validity rule quantities, so in this example the minimum quantity would be 2600 and the maximum quantity would be 10500. Fixed Days of Supply can be set but all the other order modifiers (e.g. Fixed Lot Multiple) must be unset.

3) The profile MSO: Enable Decision Rules must be set to Yes

4) The ASCP plan needs to be constrained (classic constrained, Enforce Capacity Constraint preferred or With Detailed Scheduling), a manufacturing plan, the Scheduling Zone Minutes Bucket Size in Days must be set to a value within which you want to see change over between recipes, the Use Alternate BOM/ROUTING must be checked in the Decision Rules tab.

If you set up as above and run the ASCP Standard Collection, complete refresh the results in ASCP will allocate the demand quantity to the recipes based on the preferences and the availability of resources and materials and will be correct nine times out of ten (roughly).



The WORKAROUND for this problem is to :

5) Establish a 'planning recipe'. For this you need a formula that includes the product and at least the key ingredients from the existing recipes. You should also establish a route with at least a dummy resource. The recipe validity rule should have a Recipe Use of Planning and a preference of 99 (to ensure it is only used as a last option). The minimum quantity should be set to 2600 and the maximum set to 10500. This quantity range means that, if planned orders are created that do not match the fixed quantities of the production recipes, the 'planning recipe' will be assigned and there at least will be demand for the ingredients created.
