M0001 to trigger email IT change - Assignment to feature M0001 did not take place

Hi,

I have a dynamic action as below:

0014 BETRG 06 45 M M0001

Feature M0001:

IDTXT MAIL_FOR_I0014

SUBTY 0010

OUTBX X

DISTR DIST_LIST

I have maintained text MAIL_FOR_I0014 with id PAMA in SO10 and distribution list DIST_LIST in SO04 with SAP user name logon.

But when maintain the record in IT0014 I'm having the error "Assignment to feature M0001 did not take place" and email is not sent.

Please guide me to resolve the problem.
