Hi,

I have added a field called 'select from file' in selection screen by using

PARAMETERS: p_fname LIKE rlgrap-filename.

so thet the user can give the location of the text file,from which the data can be taken.

But in the selection screen I am not getting the f4 help for this field.What can I do If I want f4 help for this field.

Regards,

Hema
