Creating Formulas 

Use

You use this procedure to create an independent formula. You can copy an existing formula if required.

Dependent formulas are created automatically when you create a recipe in which you intend to assign a dependent formula (see Formula Assignment).

Dependent formulas are characterized by the data of the recipe they belong to, that is, using the identifiers and descriptions of the recipe and stage.

Prerequisites

●     In Customizing for Specification Management in the IMG activity Specify Specification Types, you have specified at least one specification type of the specification category FORMULA and entered this specification type in Customizing for Recipe Management in the IMG activity Define and Assign Values to Environment Parameters in the environment parameter FRML_DEF_FRMLCAT.

●     If you want to create the formula with a change number, you have defined a change master record in which the valid-from date you want to use and the object types PVS Variant and Substance are active. You define the change master record, which is identified by a change number, in engineering change management.

●     If necessary, you have defined the following default values in Customizing for Recipe Management in the IMG activity Define and Assign Values to Environment Parameters:

○     In the environment parameter FRML_DEF_AUTHGRP, you have entered a default value for the authorization group.

○     In the environment parameter FRML_DEF_BASEQUAN, you have entered a default value for the base quantity.

●     In Customizing for Recipe Management in the IMG activity Define and Assign Values to Environment Parameters, you have specified the following for copying formulas:

○     In the environment parameter FRML_COPY_TEMPLATE, you have entered the inheritance template that determines the identifiers and properties to be copied.

○     If you have defined your own formula views, in the environment parameter FRML_CUSTOMER_COPY_MODULE you have entered the function module that is used to copy these views.

Procedure

Creating Formulas

...

       1.      Specify the change number with which the formula is to be created, if required.

       2.      Choose  Formulain the recipe workbench by double-clicking it.

The Edit Formula: Initial Screen appears.

       3.      Choose  with the quick info textCreate.

The Create Formula screen appears.

       4.      Enter the required data and confirm your entries.

The system shows other tab pages and the property tree in the detail area.

       5.      Enter the necessary data on the tab pages and in the property tree. For more information, see the following:

○     Identifiers

○     Scope of Application for Formulas

○     Material Data and Substance Data

○     Formula Views

○     Value Assignment

       6.      Save the formula.

Copying Formulas

...

       1.      Specify the change number with which the formula is to be created, if required.

       2.      Load  the formula that you want to copy.

       3.      Copy this formula from the hit list to the navigation area below  Formula using drag and drop.

       4.      Choose Copy in the context menu of the formula in the navigation area.

The Create Formula (with Template) dialog box appears.

       5.      Enter the required data and choose  with the quick info text Create.

The formula was copied and is displayed in the application area.

       6.      Enter more data on the tab pages and in the property tree if necessary and save the formula.

Result

The first change state of the formula has been created.
