In this window, the material and resource requirement and the replenishment time can be calculated in advance for an assembly:
artikel_resourcenberechnung.psr
This window can
- Calculate lead time for item master data
- Calculate Bill of Materials and Resource, which you need for fast forecast calculation in MRP
- Create table for Material and resource with complete material and resource requirements
Which assemblies to calculate can be selected with filters on item, item group etc using a (AND)-conjunction
Calculation lot size: The calculation lot size is the "Lot size / production", defined in the item master data.
Calculation date: Every calculation needs a delivery day. The system uses today + 100 calendar days as delivery day. It uses this day to check which Bill of Materials position or Routing position is active (Field Extended / Valid from / to). It uses the resource planning for the next 100 days. Calculation is standard backward calculation. If the resource calendar is not calculated, the system performs this automatically (beas 2020.02)
Configuration/Variant System: Configurations and Variants (formulas and scripts) are ignored in the same way as in MRP.
Short Variant: The system always uses the short variant A.
I-Version: If item version is used, the system always uses the I-Version which was defined as default I-Version in item master data.

Lead time calculate
|
Enabled: lead time is calculated based on the stored routing of the complete work order structure (order- and stock-related).
Duration is the pure "production time" in work days.
The result is entered in the field "lead time"
- Stock for stock related items is not checked. The system always calculates the complete structure
- Use Resource calendar from today + 100 at End of Production (Configuration wizard, default 3pm) and calculate backward.
- Result is duration day in calendar days. The system converts this to work days and saves this in the field "Lead Time" in the item master data.
The result is always based on "Lot size / production"
Converting to work days is always based on the main calendar.
Note: if either this or the Material and Resources Calculate setting (see below) is not active, no calculation occurs.
See item master - planning data

Material and Resources Calculate
|
Material requirement and resource requirement is calculated based on the stored routing of the complete work order structure related to the manufacturing lot size. The required material and resource times are calculated for the complete production.
The result is saved to the following tables:
BEAS_OITM_MATERIAL
BEAS_OITM_RESOURCEN
Quantities and times are stored scaled down per quantity unit.
Note:
Material requirement of the purchase parts and storage related assemblies is saved. The requirement of order related assemblies is not saved, as these are neutral for balance calculation.
Note: if either this or the Lead time Calculate setting (see above) is not active, no calculation occurs.
