Hi,
You have to WRITE PERFORM statements in the script explicitley for your requirement, when you wants to get some extra data displayed on your script output.
They are not predefined in script.
To calculate totals and sub totals in sap scripts you have to use subroutines.
Say if you have to add the unit price (KOMVD-KBERT) then in the main window whereever tat value is picked write this routine
/: DEFINE &TOT_PRICE&
/: PERFORM F_GET_PRICE IN PROGRAM <subroutine prog name> /:USING &KOMVD-KBERT& /:CHANGING &TOT_PRICE& /:ENDPERFORM
Then write the variable where ever you want it to be printed (mostly it will be in footer window)
Then create subroutine pool program and you have to write the code.
FORM F_GET_PRICE tables int_cond structure itcsy
                                    outt_cond structure itcsy. data : value type kbert.
statics   value1 type kbert.
Read int_cond table index 1.
value = int_cond-value.
value1 = value1 + value.
Read outt_cond table index 1.
outt_cond-value = value1.
Modify outt_cond index 1.
ENDFORM.
