Enter the name of the appropriate function module in field ABAP Function name if the result of the function should also be the result of the function module.
A multitude of function modules are standard in this SAP release. If these modules do not meet your needs, you can create your own by following these steps.
Create a function group for your ABAP functions
In the Top-Include of the function group enter the line TYPE-POOLS: TPLIC . The group TPLIC contains important types for the Template Analysis.
Create function modules in the function group:
First define the interface Choose the tab page Import In the rows of column Import Parameter enter:
PERIOD_FROM (starting period)
PERIOD_CNT (number of periods)
CALL_PROG (calling program); in this line enter SY-REPID in column Reference field/structure .
In the column Transfer values set the respective flag
Then choose the tab page Tables Enter RTABLE_VAL in the column Table Parameter , and TPLIC_RVAL_TAB in the column Associated type (this is contained in group TPLIC ). RTABLE_VAL is the results table; it contains the period with the resulting value of the function for each entry
Fill in fields Period , with the corresponding periods, and Value , with the results of the period (PERIOD_CNT) at the end of the coding for the ABAP-Function in the results table for each period to be evaluated.
Save your entries.
The ABAP-Function you have created is now available for when you define functions. It can be called up in field ABAP Function name (tab page Implementation ).
