In Analytics, for each Data Feed, Data Source and Datamart there should be a couple of Data Loads created automatically. If any of those are missing, try the following solutions.
Solution 1 – Deploy
Deploying (or re-deploying) the Data Source or Datamart should create the default Data Loads. If this does not help, try Solution 2.
Solution 2 – System Command
If the missing Data Loads are related to the default Data Sources and Data Feeds (Currencies, Calendar, Customer, Product, UOM etc.), ask Support to run a system redeploy command for you.
