Hi everyone 

i am trying to import my inventory to QB Desktop , my products have parent child relationship 

i first imported all the parents into Item Number, and now i am trying to import the the inventory including all the fields, however i cannot see in the mapping the field for SUBITEM IF   

i have a very big inventory (over 130 K Skues) , so it will not let me past it into "Add/Edit Multiple List Entries"

so i went to file > utilities > Import > Excel Files > and i choose Advanced Import 

it let me know map all my fields , but not the SUBITEM IF , if anyone can help here , what am  i doing wrong ? 

Thank You
