Understanding Availability Calculations

You determine the availability of components using the Material Analysis program (PCW96). You can monitor component shortages and apply quantity changes to planning messages based on shortage calculations.

You calculate material shortages using the Shortage Calculation option on the Form menu of the Work With Material Analysis of Style Items form if you want to use additional branch/plants. Otherwise, the shortage calculation runs automatically. You do not need to select the Shortage Calculation option on the Form menu if you use one branch/plant.

You can set processing options for the Material Analysis program. On the Process tab, set the Additional Branch/Plant processing option to specify the branch/plant to use with the message branch/plant for the component shortage calculation.

On the Process tab, set the Order Multiplier processing option to specify the multiplier quantity to use during the adjustment calculation to change the work order quantity.

On the Process tab, set the Minimum Quantity processing option to specify the minimum quantity to use during the adjustment calculation to change the work order quantity.

On the Work With Material Analysis of Style Items form, the Additional Branch/Plant field in the form header specifies the branch/plant to use for the shortage calculation in conjunction with the branch/plant specified in the planning message.

You can change the value in the Transaction Quantity field in the grid for each message.

To perform the shortage calculations, the system verifies the demand based on the bill of material (BOM) for the child style item in the message to determine the components and quantities required. The system then compares the component availability to the demand in the BOM to determine any material shortage. The system uses the following equation to calculate material shortage:

(Material shortage) = (Component demand) − (Availability based on message branch/plant)

If you use an additional branch/plant from which to supply material, then the shortage is calculated as:

(Material shortage) = (Component demand) − (Availability based on message branch/plant) − (Availability based on additional branch/plant)
