whay a user recieved a workintem in his SAP inbox

Hello,

I have been asked to find out why a workflow document was in a users SAP inbox. the task that generated the workitem was TS00008046. I am not that knowledgeable in workflow but I am checking the Task in PFTC and I cannot determine how the work item was sent to his inbox. Since this has heppened we have assigned this task to a position so now the people in this position receive these notifications.

if someone could please lete me know what I can checked to find out this information, it would be a big help

thanks in advance
