Hello,
If I have a rule that calculates a value for Jan and then in February, I STET that rule for Jan. Will the calculated values be retained?

In theory no, in practice they may well be buffered. But the behaviour when you add and subtract rules has the potential to be version specific. Note what Lotsaram said recently about a change that he encountered in 9.5.1, though this is the opposite of what you're doing:

To be safe, if you're changing the rules in this kind of fashion it's much safer to reboot the server after doing so. If you absolutely cannot do that, it would be wise to at least create a view of the area that used to contain the values, and explicitly zero that out.

What do you mean "retained"? As Alan mentions they may well continue to float around in the back of the back end of TM1, but there is no way that a user will be able to get to them. The new rule will set it to stet, so they user will see an inputtable field.
