Hi all,

I am implementing user-exit EMDI0001 IS-U: Installation - subscreen integration and field check.

I added my field to the screen, now I need it to be saved in the DB when the user saves his work; what exact structure should I map onto my screen?

Another question: on this field I need help with research, but the need is specific, there are specific classes existing in my environment that I can use, but how to set this up? With specific search help and specific ABAP code? Do an AT SELECTION-SCREEN ON VALUE-REQUEST FOR myfield? But in which exit function?

Thank you in advance for your help.
