Hi,

I think variable OK_CODE is not assigned to the OK button. Go to screen 100. Goto "Element List" tab and check whether OK_CODE variable is assigned to "OK" (Type of screen element) in "general attr" tab.

Regards,

Siva.

Hi there.

By Siva: "I think variable OK_CODE is not assigned to the OK button" <- this really could be the reason.

However, i've noticed something strange in PAI of screen 100. Why did you insert module user_command_0100 twice? Comment the first one, and use the last one (should be last command of your PAI.

But my advice is to insert a break-point at statement save_ok = ok_code to see if it's triggered or not.

Regards.

Valter Oliveira.

Hi,

change this code.

save_ok = ok_code.....change this as:

save_ok = sy-ucomm.

Hi,

You can make the following changes:

1. Remove the module User_command_100 in the first line.

2. Check whether Ok_code has been assigned properly.

3. Put a debug point and check whether the PAI is getting triggered.

4. The Table Control code should be at the beginning of the PAI event.

Hope this helps.

Thanks,

Samantak.
