In my previous question a SDN user has posted that link about how to use ABAP code in IDOC segment conversion rules:
[http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/2782] [original link is broken] [original link is broken] [original link is broken];
In that moment I didn't need that, but now I want to use because I have to modify a field, doing a SELECT SINGLE to the database with an other field value from the same segment in the WHERE condition.
The blog is very clear and I've done all the steps, but the user exit isn't executed during the IDOC input test in WE19...
I've used an infinite loop at the beggining of the exit to be sure than nothing is happening there, and now I don't know what can be wrong:
- The exit is active
- The rule is created and defined for the segment that I need
- The rule is assigned to the message type
What else I have to do?
