Set initial value in a table field


HI all,

I have to test some programs and want to clear values in tables to check the behavior of a program when dealing with initial values.

I using this code:

parameters: p_pernr type pa0105-pernr,

p_val type pa0105-usrid.

data: ls_pa0105 type pa0105.

select single * from pa0105 into ls_pa0105

where subty = '0001'

and pernr = p_pernr.

if sy-subrc = 0.

if p_val is initial.

clear ls_pa0105-usrid.


ls_pa0105-usrid = p_val.


modify pa0105 from ls_pa0105.


This works if I put a value in p_val but it does nothing if I leave p_val initial.

Even if I clear the field, when I execute the modify, nothing has change in the table.

Thanks for any help.
