FM CRMPSST_FIND_ACTUAL_STATUS

Hi

in FM CRMPSST_FIND_ACTUAL_STATUS

Im passing parameters

IS_STATUS - " Im passing User Status" and selecting X for STAT_FIELD, DATE_FIELD AND TIME_FIELD

IS_JSTO - This GUID im selecting from CRM_JSTO table

OBJNR - What GUID should i be passing for this? I tried using same GUID from CRM_JSTO table but im not getting any output values

Im assuming im not passing the correct parameter values, please point me in right direction
