If Not Using OCM Can User Be Removed From ROLE "AR_CMGT_CREDIT_ANALYST_ROLE

 Hi All,

My goal is to avoid receiving unwanted notifications from workflow "AR Credit Management Application Process" (ARCMGTAP). We have tried removing the particular USER from the ROLE assigned to this workflow. But after some time , thse users are getting created again. We are not sure, why the USER is creating again (we suspect that Workflow Background Process concurrent request is creating the USER againa, but not sure). Please let us know the which package/procedure/mechanism creating them again. 

API to remove the users from the existing ROLE:

DECLARE 

v_role_name varchar2(100); 

v_user_name varchar2(100); 

BEGIN 

v_role_name := 'AR_CMGT_CREDIT_ANALYST_ROLE';
