Hello

This is regarding guidelines on providing filters on fields/attributes in TMF677.

I had already referred chapter 1 of Design guidelines which provides detail about operators and how to support filtering.

My question is specific to TMF677 and would like to know are there any guidelines on which fields the filtering be provided, 

E.g. Is it necessary to provide filtering on "type": "appliedBillingCredit" or "appliedBillingDebit"?

Are there any specifics for each TMF specification on which fields the filtering be supported?

Thank you in advance.
