Programmatically insert Major/Minor and Categories

Hi,

I am trying to create a program to insert fixed assets. My code inserts the major and minor flex values in the FND_FLEX_VALUES and FND_FLEX_VALUES_TL tables. then I am inserting the category information in the following tables: FA_CATEGORIES_TL, FA_CATEGORIES_B, FA_CATEGORY_BOOK_DEFAULTS, and FA_CATEGORY_BOOKS. My customer service rep can see the major and minors on the front end but cannot pull up the categories. Am I missing a table to insert information to so it will link the categories to the major and minor?

Thank you,

Lisa
