Routine in DTP

Question

Hello Experts,
I need your help in programming a routine in a dtp.
I have a DSO and want to load this data into a Cube. But I just want to load data if month of the first date (0bill_date) is not equal with the month of the second date (0serv_date).
Can anybody help me to create the coding?

Answer 1

some further questions :
- Do I need coding in global part?
- how to define "V_REC" ?
Actual Coding in start routine is as follows:
$$ begin of global - insert your declaration only below this line  -
... "insert your code here
$$ end of global - insert your declaration only before this line   -
