Need help on ALV Grid Control

Question

Hi,
I have written a program to display the details of customer in ALV Grid. I have also added code to add a hyperlink to the field name - KTOKD of the table KNA1. It would be helpful if anyone could tell me what is wrong with the code. The list is correctly displayed but the hyperlink is not working.
tables kna1.
data: BEGIN OF itkna1 OCCURS 0,
         ktokd like kna1-ktokd,
         kunnr like kna1-kunnr,
         name1 like kna1-name1,
         name2 like kna1-name2,
         ktokd_hdl type int4,
      end of itkna1.

Answer 1

Try this..
give the field name in CAPITAL LETTERS..
*prepare field catalog
clear: it_fcat, tmp_fcat.
tmp_fcat-fieldname = 'KTOKD'.
tmp_fcat-ref_table = 'KNA1'.
tmp_fcat-ref_field = 'KTOKD'.
tmp_fcat-col_pos = '1'.
tmp_fcat-web_field =<b> 'KTOKD_HDL'.</b>
