Can somebody help me in the following problem
I have make a customizing Dialoge.
The SAP system has generate two Screens. 25 and 26. One have to give some must values on screen 25. I have program it so that when a must value on Screen 25 is not available then it shows a massage. But after the massage the screen changes to screen 26. But I want that it stays on Screen 25 so that I can fill in missing value. I have tried it with leave to screen but no effect.
When somebody can help me it is very nice.
