Key date & variable

Hi,

I want to derive the low value of a variable for the key date. I've created a user exit variable (Z_KEYDATE) which is not ready for input and optional.

The code is quite simple and I expect it to work. However when I run the report, I get a dump as "DATE INVALID". When I check the dump details and debug, I see that date is passed as "00000000".

I can't debug the following code because keydate variable does not run through it.

There's something wrong but somehow I can't find it. Any suggestions?

Thanks!

  WHEN 'Z_KEYDATE'. " Keydate    IF i_step = 2.      LOOP AT i_t_var_range INTO loc_var_range      WHERE vnam = 'Z_CALDAY'.        l_s_range-low = loc_var_range-low.        l_s_range-sign = 'I'.        l_s_range-opt  = 'EQ'.        APPEND l_s_range TO e_t_range.      endloop.    endif.
