Realization of the Function (SAP Library - Cost Center Planning (CO-OM-CCA))

Realization of the Function

Use

In the Implementation view

Assign an ABAP program function to the logical function (with reference field)

As an option, use a data element to determine the Possible entries for functions (in cases with reference fields)

Fill the Result field for the function (in cases with function references)

For a function in the hierarchy derived from an existing function, include the associated sub-function (in cases with reference functions)

Features

Assigning Realizations (Field or Function references)

You can base a logical function on function modules or table fields, meaning that the function result comes from a module or from field contents. Make entries either in the ABAP function name field for a function module, or in the fields Table name and Field name for the table field.

Function Result Types

Functions based on function modules can have the following result types:

Number Value/String: Useful for functions in activity quantities and activation.

Boolean values (true/false): this result type is useful for functions in the activation editor that have true/false results.

Functions with reference to a function module must either use Type of Parameter or Type of Function.

Type of parameter: Useful for functions in object determination. Choose (F4) a function parameter in the field that determines the type at the time of processing. A parameter of this result type can refer to different table fields. It is therefore more flexible than a type for a given, fixed table field.

For the function COMPONENTS_OF_GROUP, you enter ABAP parameter GROUP_FIELD in the Results field. In template maintenance, you enter the function SEND_PROCESS as a parameter.

Type of Function: This result type (or Type of Parameter) must be used for functions in object determination. Through F4 choose from the valid functions.

Using Data Elements for Determining/Selecting Possible Entries

Comparison

During comparisons in the framework of defining Methods, the Possible entries function for comparison operand 2 offers only those functions with data elements agreeing with those for comparison operand 1. Each function that is realized as a table field is assigned a data element via the ABAP Dictionary. Functions realized as function modules have no data element assignments.

You can use the F4 data element field to change the existing assignment, or create an assignment (for functions with reference to function modules) that makes additional comparisons possible.

If the function you selected as comparison operand 1 is assigned data element KOKRS, the R/3 System will not offer functions for comparison operand 2 using the assigned data element BUKRS. In order to allow compares with both these functions, you must assign both functions the same data element, such as ORG_UNIT.

If you enter an asterisk ( * ) in the F4 data element field, this function appears for all instances of comparison operand 2, as long as it is generally available in this context.

Selecting Parameters

By using F4 for parameters, you call up a selection list of only those functions whose data elements match those of the parameters. If you enter a data element, in addition to the above, you will also call up all functions that contain the given data elements.
