hi all,

i want to validate sy-ucomm because whenever user press enter the values on the screen change, the auto no generate after every enter, my screen is with table control where user enter data and after that he will get doc. no after saving the doc.

generally for ENTER sy-ucomm will be /00 .. Just give /h and press enter in debugging you can find the sy-ucomm value .

Is this you are expecting if not please elobarate your question .

Hi Amol,

Whenever you press any key/do some user action the modules in PAI group are called. The sy-ucomm/user command for Enter (or any key) depends on the screen on which it is currently in.

As sugg, by Kamesh, do a '/h' and then press enter. See the sy-ucomm value and code a module in PAI of the screen for validation.
