dynamic configuration in integration process using abap mapping

Hi everybody,

i have the following scenario:

file adapter -> integration process -> file adapter

The integration process uses an ABAP mapping and sets the filename in dynamic configuration as follows:

*-- Set Parameter

    clear ls_dyn_record.

    ls_dyn_record-name      = gc_dyn_config_name.

    ls_dyn_record-namespace = gc_dyn_config_ns.

    ls_dyn_record-value     = <new_file_name>

*-- Write configuration

    ir_dyn_config->add_record( ls_dyn_record ).

But now the new filename is not reflected in the file adapter (receiver). In the integration monitor (SXMB_MONI) i still find the old filename.

Whats wrong?
