I wonder whether I can insert an empty value into my search help. In alv grid there's a cell with search help. With respect to my case, if the user choose '01' from search help, I want the report to show error message like "In this case you can't choose 01". Then I delete the value from the cell but this time the report shows another error message "Invalid Input". If I had an empty value in my search help, the user would choose it so he would have deleted the value. But I don't know how can I achieve this?
Any help will be appreciated.
