Line selection on Dynpro

Former Member — Tue, 11 Nov 2008 12:19:46 GMT

Hi experts,

I have a table-control in screen 100.

I have a line-selector: L_SEL type char.

How can I check wheter a line is selected on the screen or not?

Hi Mrwhite,

When you create a table control, you need to define a check field in your internal table, so you can control lines selecteds.

I defined it, but it isn't working. I also defined it in the program. I would need a sample program.
