I have created a ALV grid in ABAP OOP.
Want to give F4 help fo rthe material which is key coulmn in the grid. What all the values i need to set in the fieldcatalog for this.
F4AVAILABL = X
checktable = "MARA'.
ref_table = 'MARA'.
ref_field = 'MATNR'
VALEXI = X
When ever i enter a material in the grid, i get the meesage as invalid value.
Is there any problem in the fieldcatalog as mentioned above
