This is a challenge as its unclear what the context is.

But here are my general tips:

• If anything, ensure you always update your TM's on the fly.
  Often this means Ctrl+Enter (although short cut can be customised)
  This means you are sure all your translations and efforts are saved into the TM
• It is best practice to always perform a finalise at the end of your project - just before you generate target translations.
  As this will ensure that all your final efforts are saved, including any that got amended during revision as well as generate the target translations
  During Batch Task - Update Translation Memory, ensure that you have all the required segments enabled for update
  As you may have left some segments with a draft status or in another state
