Editabel ALV issue
I have a requirement below,
In my editable ALV, suppose i have 4 columns a,b,c,d
Column a & b are ready for input, but c & d disabled and calculated based on a & b's input.
Now when user makes some entry in a, then based on some formula column 'C' should be populated and same with b and d.
what event should i capture to get the best results. I can write the code 'on enter', but there is possibilty that user uses 'mouse' or 'tab' to move b/w columns.
