More than a few times the analysis of issues regarding conditions in documents like POs, SOs, etc have me checking their Condition Record as the first step. Be it Message Output Type or Pricing Conditions or Tax Conditions. Also, for request like View Condition records through Table from my Master Data team or colleague so that they can take dumps of the same or check if the request for maintaining a certain value in the Condition Record, recently I have the best possible answer for them. I owe this discovery to a senior Technical Consultant who showed me what i consider a trick !
First we go to the display transaction of the corresponding condition record MN06, VK13, FV13, MN03, MN09, MN15, MRM3, etc
Since I am an MM consultant will go with MN06 here for illustration purpose;
On the first screen we can select any Key combination for the desired output message, here we have 0003
Then we are prompted to choose the key combination, we will choose any as our objective is a complete list of values maintained irrespective of a particular Key combination chosen now;
The trick now is to fill the mandatory field (with anything, giberrish will do as shown below 
) and hit the Condition Info button.
We are again prompted to select the desired condition,
now we see a screen with no mandatory fields
and on execution of the same.. TaDa !
We have the list of all the values maintained in the condition record. For further beautification click the ALV button on top and we have options to search and extract this data.
Hope you find this as useful as I do. Would love to hear back from you on this and all else 
Wishing you a good life !
