Asset import with FBDI with only major category

Hi There,

We have few categories in FA with only major category and minor is null. I am not able import such assets via FBDI. Prepare asset transaction data program give error "Invalid Category". I can see those categories in set up. I am able to import all assets with major, minor category successfully.

Has anyone come across this issue? Let me know resolution and/or changes in FBDI to import such assets successfully.
