Description: A Primary CDR refers to the first CDR for a PDP. Subsequent CDR's, called secondary CDR's, will be opened when the primary CDR is closed by triggers like exceeding data volume limit, max number of charging condition changes, SGSN change, etc., A Partial CDR is such subsequent CDR in which some fields, like Access Point Name, PDP Type, etc., that cannot change during the life time of the PDP are not included. This object controls the generation of partial CDRs on GGSN. When set to 'true', partial CDR's are generated. When set to 'false', partial CDR's are not generated i.e., all the fields are sent in the CDR.
