Dynamic Fieldname assignment

Former Member — Wed, 04 Jun 2008 03:11:21 GMT

Hi,

How to get the field name dynamically from an internal table.

For ex:

I need to assign some fields based on some condition, but i dont know which fields meet the condition.

Loop at it_pos.

Loop at it_fieldcat.

if it_fieldcat-no_out = ' '.

this code is giving error, what is the correct syntax for such assignments

Thanks,

Ravi K

HI,

Better way to do this is to use field symbols.

Use class cl_abap_structdescr to get the components of your structure and then use field symbols to compare values

ASSIGN COMPONENT <comp> OF STRUCTURE <your structure> TO <FS>.
