Hi
/*$$SNPS_START_KEYSNP$CRDWG_TABLESNP$CRTABLE_NAME=FileNameSNP$CRLOAD_FILE=#Default_location\<%=odiRef.getContext("CTX_NAME")%>\cm_mstr.txtSNP$CRFILE_FORMAT=DSNP$CRFILE_SEP_FIELD=0x0009SNP$
CRFILE_SEP_LINE=0x000D0x000ASNP$CRFILE_FIRST_ROW=0SNP$CRFILE_ENC_FIELD=SNP$CRFILE_DEC_SEP=SNP$
aboce code is generated by odi during loading step in an interface.
Suppose you want select * from emp
Now odi replace this emp table by the code.The above code seems like a table which in turn refer to the file.
CRFILE_FIRST_ROW= *0*
See the bold part. Here zero refers to the 1st line of file.Then it is incremented up to the last line to fecth line by line.For more details on it refer

Thanks
