If no date was entered, it is valid always, otherwise only in the specified period.
Precalculation:
Precalculation date serves as reference. In Precalculation, all BoM positions are displayed but only the valid ones are valued.
Production
Depending on Configuration wizard > Production > Capacity planning > Default calculation method
Calculation backwards:
Delivery date serves as reference. It is checked only at work order creation. If the delivery date is changed subsequently, there is no second check as long as the work order is not updated.
Item-Processing time:
The Delivery date of the respective assembly serves as reference. The item-processing time of the respective assembly will always be used for the calculation of the completion date of a sub-assembly (beas 9.1 PL: 08).
The parameter "validdate" can be defined additionally, if the work order will be created via the API. (beas 9.1 PL: 08) declare=wo=ue_api_wo // .. normal script to create or refresh a work order |
Sales order in Order recommendation
At breakdown of the assemblies the delivery date of the sales order is used, minus the average delivery time, stored in the Configuration wizard.
Special case: Configuration wizard > Production > Capacity planning > Default calculation method = Default calculation method
The calculated date of requirement of the respective sub-assemblies is used as reference date for sub-assemblies.
Example 1
A supplier changes the item number from a given date
Pos 10: previous item number until date x
Pos 20: new item number from date x+1
Example 2
At date x additional material is required.
If larger changes are needed, we recommend to use item version control.
