I used the table1FE/0DTE14IT00 in some of my past reporting requirements but I can't find it in my new BRIM system. I can't find any documentation on this either. Can someone please help me understand how to make this table available? Is there some functionality that needs to be enabled?
These are auto generated tables based on the billable item classes created. So, check what are the bit classes you have in your current project and it should mostly be /1FE/*14IT00 where the * to be replaced with the BIT class.
Faisal rightly said these are auto generated tables. Just to add one more point.
These tables are generated when you generate your bit class . So please try to check in bit class generation path in SPRO. If it is still missing,sometime bit class is not correctly generated. In this case just delete the bit class and generate it once more. Be careful while doing this process, this suggestion is only for non productive systems like development.
