A material check can be activated which reserves the material stock or all planned accesses for the work orders by priority (soft reservation).
A copy of the warehouse stock of goods issues is created and these are then assigned to the work orders by priority (sorting of the production list). If no planned issue is available, a possible issue is used: current day + lead time of the item in question.
Note: The material check is only performed if the calculation is started in the APS view (List). For a material check, the entire production must always be seen, and the previously planned work orders must be considered. For this reason, it is important that all work orders planned and to be planned are displayed in the list, and that the previously planned work orders are at the start of the list. In this manner, during the material check the Only calculate unplanned option is ignored for the material check itself.
Only items with positive stock inventories, which are not blocked and are released from Beas side, are taken into account.
If a material is unavailable for a work order, this is displayed in the Gantt chart using a symbol. The missing material and the planned receipts can also be displayed in the list display and the Gantt chart.
After scheduling *1
In the material calculation after scheduling, the latest possible material receipt is calculated. The material is not correct if the previously calculated start date of the position cannot be fulfilled.
Before scheduling *2
In material calculation before scheduling, the earliest possible material receipt is calculated irrespective of the required date and this is entered as the earliest material receipt in the position.
If Consider material entry is activated in the calculation step, the material entry determined here is considered and the operation is only started if the material is available. This only works for forward scheduling.
If the missing material is an assembly (not order related) and there is already a work order, this assembly and this work order has a lower priority according to APS y View > Production List, the priority is changed automatically, i.e. the work order is moved up in the list. If Consider material entry is activated in the calculation step, it ensures that the sub-assemblies are always scheduled before the higher-level assemblies.
Pre- and post-scheduling
Under certain circumstances, it may be logical to activate both variants.
Important:
The "earliest possible start date" information is overwritten in the operation with "latest possible".
Notes on material control:
•A stock reservation has always higher priority (beas 9.3 PL 2 HF 4)
•Order-related assembly BOM items are completely ignored, because it is assumed that the associated manufacturing position exists in the same amount. The system ignore higher or lower quantity sub-assembly
Reservation between bill of material position and work order positions are ignored.
•Material requirement coverage is tested as follows:
oIs stock available?
oDoes a planned production receipt exist? (* 2)
•Stock allocation:
oCheck only Stock, which not reserved
▪Is stock available?
▪Inventory allocation?
▪Earliest production receipt ? (* 1)
▪Earliest purchase order ? (* 1)
▪Earliest replenishment date ? (* 1)
oTemporarily Reservations (late as possible, for material control after dispatching)
▪Is stock sufficient?
▪Latest possible production receipt, completed before the requirement date
▪Latest possible purchase order receipt
▪Inventory allocation?
▪Earliest production receipt - possibly at a later date? (* 1)
▪Earliest purchase receipt - possibly at a later date? (* 1)
▪Earliest replenishment date? (* 1)
(* 1) Special features of this calculation steps:
In "Material check after scheduling" "too late" is active if the planned receipt is over the requirement date. The requirement date is the calculated completion date or the start date of the assigned work order. The planned receipts are assigned to the position and can be represented in the GSP list.
(* 2) Only with "material check before scheduling":
If a work order is determined, it is first scheduled. This ensures that the work order is finished earlier and can cover the requirements as soon as possible.
Consider WareHouse
•Negative Stock is not allowed.
•Ignore locked Warehouses.
•Type not "Blocked WareHouse"
•Reservations always have the highest priority.
•If a locked batch is in a production warehouse, then the batch number is available for production.
•Item Versions are not considered (no check on Batch/Serial number level)
Material linked to external routing positions
Material positions linked to an external routing position can reserve quantity which is available in an external warehouse.(beas 9.3 PL 2 HF 4)
