I have created an Editable ALV using OOP. My requirement is to show calendar for inputting a date on a field.
I have created event handler and register for events.
I have also appended in Fieldcat
lt_fieldcatalog-f4availabl = 'X'.
lt_fieldcatalog-ref_table = 'SYST'.
lt_fieldcatalog-ref_field = 'DATUM'.
But still not working.
I am getting an runtime error "GETWA_NOT_ASSIGNED"
Short text : "Field symbol has not yet been assigned."
Please guide me to implement calendar on F4.
