I have the following dimension. TP|.1m|Dm. This is a circle on a plane that is TP to another Circle (Datum D) on the same plane. Am I allowed to add bonus from each circle to the TP tolerance? How do you calculate it for both?
bonus from MMC question

From the first, yes. From the second (-D-), no. The second is for datum shift on a hard gage. I would add that if no other features are positioned from -D- then adding that bonus would be fine.
I'll leave it to Kev, our resident GD&T guru to correct and clarify.

You're using 4.1. Use the XactMeasure GD&T, and it will handle the bonus correctly. No need to try to do additional math...
If D does have a virtual condition, PC-DMIS will also take that into account. Be careful though: read the portion in ASME Y14.5 on "Simultaneous Requirements". You can set this (and I verified that it works!) under Insert/Dimensions/Simultaneous Evaluation . Thanks to Mr. Botta, I am now doing this right.

Now go back to Insert/Dimension/Perpendicularity. That pops up a window called "XactMeasure GD&T - Perpendicular Dimension". follow the instructions. It is pretty simple to work wth these things...

Tip: Also, if your using 4.1 never create or define a Datum to a feature set. Unless of course you want to Delete your program without warning.
If your Datum is pattern of features, you have to use v4.2.Mr. Comment

Woawww, thanks! I have not done this YET! I do have a few parts coming up where I have to get into this. Thanks for the heads-up.
