Auto-updating AddrRecId while importing flat files

Hi ! , i am currently programming a software that generate .dat files which are imported into axapta. At this moment i am working on the importation of the Address Table. So my software generate a correct .DAT files with the corrects AddrRecId which containts the recID’s of the customer the adress is belonged. But when i do the importation in Axapta i don’t know why but Axapta change my AddrRecId value’s by a sequence of number (seems to be taken from the sequence number normal recid) so in the axapta tables the addreErcId’s are wrong and the adress don’t display in the forms. So my question is: How Can i disable this “auto-updating” of the addrRecId field ? Thanks !
