ALV: modify invalid user input after entry

yuriy_dzhenyeyev — Wed, 24 May 2023 09:09:40 GMT

Given an ALV table with a NUMC column, it is possible to enter a text value there (say, 'test'), but a pop-up error message will be shown.

Is it possible to intervene programmatically (data_changed?), replace 'test' with '123' and have ALV validate the input once again? For the user it should look like:

- enter 'test' into the NUMC column

- press ENTER

- '123' is displayed instead, the input is valid

It's technically impossible to type alphabet characters if the field is of type NUMC...

EDIT: sorry, my bad, weird but true. Example with table SFLIGHT, field CONNID:

You can change the value via the event DATA_CHANGED (via the method MODIFY_CELL of the event parameter ER_DATA_CHANGED), but it won't go through the ALV validation again, I guess. Why do you want to validate it again if you pass a valid value?
