Hi Team 

Create a Project "Admin" and linked it to Contract "ADMIN000XX" and link the Item and link the item to a Category "ADMIN"  

lately it seems like on the Material Category list,  it has dropped the Category and as a result AP Invoice batches are not posted are giving a error the Category does not exist.

However we have previous invoices posted,  to that contract. For some reason it just dropped the category and when you go to PJC to add it back on. it says the category already exist.
