Defining Material Quantity Calculation

Use

You use this procedure in the process order to define formulas (or adjust formulas taken over from the master recipe) for the calculation of the following values:

The operation quantity or any interim results
The phase quantity, the expected phase scrap, or any interim results
The quantity of a material component or any interim results
The product or order quantity or any interim results

If required, you transfer the formula results to the order.

When you enter a formula for the product quantity, note that after the product quantity has been calculated the system only updates dependent values for which a formula has been maintained. For this reason, you must also enter a formula for the values that are proportional to the product quantity.

In collective orders, material quantity calculation is only supported within the leading order. Header quantities and component quantities of subordinate orders are calculated in proportion to the product quantity of the leading order. For this reason, do not enter formulas for:

Directly-produced components of the leading order
Materials or phases of subordinate orders

Prerequisites

The process order was created with a production version.

For you to be able to take into account material properties such as the active ingredient potency in material quantity calculation, the following requirements must be met:

It must be possible to enter the property as a numeric value.
You must classify the material master record or the component in the material list with a class of class type Batch.
You must assign the property as a characteristic to this class and assign a value to it in the material master record or the material list of the process order.

Material quantity calculation uses the value from the material list or, if this value is missing, the value from the material master record. If multiple values or value ranges have been defined, the system uses the lowest value.

To transfer the scrap calculated in material quantity calculation to the corresponding phase in the process order, you must have activated scrap management in the parameters of the relevant order type (see Customizing for Process Orders).

Procedure

Choose

Materials in the process order.

The material list appears.

Choose

The Material Quantity Calculation screen appears. It consists of two sections:

The lower section contains one line with data for each operation, phase, and material contained in the recipe.
In the Formula definition section, you can display the formula defined for the field that you have selected in the lower section.

Place the cursor on the field for which you want to enter a formula and choose Select formula.

Enter the required formula in the Formula definition section. Insert the elements of this formula as follows:

Use the keyboard to enter number constants.

Use the decimal markers defined in your user defaults or the decimal point.

To insert a reference to a material or a material property in the formula, double-click the relevant field.

The coordinates of the field are inserted in the formula. When the material quantity is calculated, they are replaced with the up-to-date quantity.

Note that the system does not take the unit of measure of referred values into account. Percentages, for example, are treated like absolute values during the calculation.

To insert the operators of the basic arithmetical operations or a bracket in the formula, choose the corresponding button in the Formula definition section or use the keyboard to enter the sign.
Use the keyboard to enter all other operators or functions.

For information on the available operators and functions, see Basic Functions of Material Quantity Calculation and Material Quantity Calculation with Batch Data.

Depending on the values for which your have entered a formula, start the calculation as follows:

If you want to recalculate component, operation, phase, or scrap quantities, choose .
If you want to recalculate the product or order quantity, choose Calculate product qty.

The system calculates the product quantity and subsequently updates all component, operation, phase, and scrap quantities for which formulas have been maintained.

The system displays the calculated values in the corresponding fields in the lower screen section.

Save your entries as follows:

If you want to save the formulas without transferring the formula results to the order, choose and save the process order.
If you want to save the formulas and transfer the calculated material quantities to the order, choose and save the process order.

The system also copies the calculated material quantities to the order if the Fixed quantity indicator has been set for the component of the material list.
