BAPI_ACTIVITYCRM_GETDETAILMULT Status GUID problem

Hi,

Can anyone tell me what is the link between the GUID and the REF_GUID of the status paramter?

CALL FUNCTION 'BAPI_ACTIVITYCRM_GETDETAILMULT'

TABLES

guid = lt_guid

header = lt_header

partner = lt_partner

organisation = lt_organization

date = lt_date

text = lt_text

reason = lt_reason

outcome = lt_outcome

status = lt_status

location = lt_location

listofrelations = lt_listofrelations

partobj_select = lt_partobj

return = lt_return

journal = lt_journal

documents = lt_documents

material = lt_material

extensionout = lt_extension.

I want to know how to relate lt_guid and GUID of lt_status.

Regards,

Subhashini
