Compute resources

Inventory > Item structure > Item structure right click menu > Compute resources 

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.

Function	Description
Item from  / to	Selection filter for Item area Note: Only items are calculated, which - not marked as deleted - Procurement Method is "Make" - Flag "Warehouse item" is active
Item group	Additional filter item group
Item property	Additional filter item property
Employee	Additional filter Employee defined in item master data
Calculate lead time	if active, it calculates the lead time for an assembly 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 into 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   See item master - planning data
Calculate material and resources	if active, it calculate material and resource requirement 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.

To perform the computation on a regular basis, you can create an activity.
