Title

FMDERIVE Customer User Exits

Functionality

This function module is a component of the SAP enhancement SAPLFMDT, a User Exit for the step rule type "Enhancement" specifically designed forthe FM Derivation Tool. EXIT_SAPLFMDT_001 provides the following parameters:

IMPORTING PARAMETERS:

I_ENVIRONMENT Contains the value 'SAP'

I_DERIVATION_DATE Contains the Derivation Date (example: posting date)

I_STEP_ID Contains the user-defined step ID. The USER EXIT

is used by all step rules and the step ID number

should be used to link to the correct part of

the USER EXIT

I_FMDERIVE_SOURCE Structure FMDERIVE that contains values used

as source fields following the step rule. Only

the source fields defined in the step rule are

entered into the structure

EXPORTING PARAMETERS:

E_FMDERIVE_TARGET Structure FMDERIVE that should return the values

used as target fields following the step

rule. Only the target fields defined in the

step rule are passed back to the structure

E_EXIT_IS_ACTIVE Flag to indicate when the USER EXIT is active

("X") for each step rule

E_FAILED Indicates that the USER EXIT failed to derive

the values

EXCEPTIONS:

DERIVED_FAILED Indicates that the derivation failed

Notes

• You have to create the Include ZXFMDTU01 and maintain your USER EXIT.

• If you have more than one step rule type "Enhancement" (transaction FMDERIVE), you should consider maintaining a different value for the step-ID number. This is how you can differentiate between steps. In addition, set the value of the export parameter E_EXIT_IS_ACTIVE = 'X' so that the user exit is active for the specific step ID.
