HCM P & F - Read Back-end information from the formular

Hello!

A new Problem...First I new in the HCM P & F in combination with ISR. After a lot of problems i was able to start the service an now i have a new problem.

I want to read information from the back-end Information when the user press a button on the form. To get this information i have to start a programm - so i need to implement it anywhere.

I am a little bit confused about to realize this. First I tried the BAdI QISR1 with the EVENT and the parameter USER_COMMAND. Then i read about the DO_OPERATIONS? But in both case, no break point was triggered.

Can anybody please explan the corret way to realize this - thanks!

Best greeting,

Gregor
