How To Remove A Person (MEMBER) From A Group

Hello everyone!

I'm trying to remove member from a group by using this api EGO_PARTY_PUB.Remove_Group_Member. The problem is that when I'm running the procedure it's has nothing to commit and member is not getting removed. Is there any alternative for this api or maybe I'm using it in wrong way?

Here is my code:

declare 

  l_object_version_no_rel number;

  l_return_status varchar2(240);

  l_x_msg_count number;

  l_x_msg_data varchar2(240);

  begin

 EGO_PARTY_PUB.Remove_Group_Member(

  p_api_version    =>  1.0,

  p_init_msg_list    => 'T',

  p_commit       =>  'F',

  p_relationship_id   =>123456,
