Dynamic assignment problems!

[Former Member]

Hi gurus!

I´m having some problems with dynamic assignments. The problem is as follows: in my program I have some Parameters and some Select-Options. In some cases, I have to change the value of this variables in a dynamic way. When I run the program, the value that I read from the table and I assign it to the variable is not changed (for example I want to change the value from P_BUKRS).

I include the source code. Any ideas?

Header Line contains the following record:

t_zfii018-var_name = P_BUKRS

t_zfii018-ruta = 3245

Hi Esteban.

Maybe it is connect to two things i discovered:

1: You should put the field in the second assign statement into brackets.

ASSIGN (t_zfii018-ruta) TO <fs_table>.

Then <fs_table> points to P_BUKRS.

2: You never move a new value to P_BUKRS or <fs_table>.

Timo.
