a) The first way is to use the command \’&SAP_EDIT\’ once in transaction SE16N.
Step 1: Display the table to be updated in transaction SE16N.
Step 2: Once in display mode, please enter the command \’&SAP_EDIT\’ in the transaction code box (please refer to the screenshot below) and press the button \’Enter\’.
And the fields will become editable.
b) The second way is via debug mode (in case the first method does not works):
Step 1: Enter debug mode (using the command \’\\h\’) with the table to be updated in transaction SE16N.
Step 2: Change the value of variables \’gd-sapedit\’ and \’gd-edit\’ to \’X\’ (please refer to the screenshot below).
And the fields will become editable.
