What packages files should I register in register flagged files ?

Hi,

I'm working on OEBS R12.1.3.

We are using OAM register flagged files to record customized forms, reports, packages, ... but also to register private packages called by custom programs, so that we are warned by adpatch when those packages are updated.

As of now :

- we register packages whose name end by _PVT

- we do not register packages whose name end by _PUB.

My question is : Should we register %_UTIL packages usage in custom code ?

fro example :

- oe_flex_util.get_concat_value

- OE_LINE_UTIL.Get_Reserved_Quantity

I guess that if we start to do so, Register Flagged Files volume will rapidly increase.
