function module: get/set paramter id

Hi togehter,

i would like to use the activity task list in qm notification (behind is a function module) to start an other transaction. That works fine so far but i would us some paramter id's from the qm notification which should be set to the transaction which i will start with that function module.

But it dosent't work if i expected...

DATA: p_matnr like viqmel-matnr-

set Parameter id 'MAT' field p_matnr.

Call Transaction 'CA02'.
