Table Control u2013 Dynamic F4 Help

Hi All,

I am creating table control and having a requirement where depending on the input of COL1, F4 help for COL2 will vary. While entering data in current row its showing corresponding F4 help for COL2. (Here I need to press enter after putting value in COL1 so F4 help for COL2 can be generated.). But if I am moving to previous rows itu2019s not showing the F4 help that should come corresponding to COL1 in that row, instead its showing current F4 help in all rows for COL2 irrespective to row whou2019s COL2 I am pressing F4.

.

I want on clicking or pressing F4 help for COL2 corresponding to COL1 should come up for all the row in display/edit mode.

Please advice how can I proceed further.
