FM to retreive CRM scrren patner determination headers

Hi everyone ,

1.) I have a serious doubt on how to retrieve the data frm "assigned to" , "logged by" , and "tester" which are the header files on the ticket creeation screen. I have used the FM CRM_ORDER_READ. I could retieve rest of the screen details. Is there any FM to retrieve the values of other partner determination header files ?

2.) is that possible to add one more partner determination header file like one more "logged by". There are options to add only 4 headers.

Thanks in advance
