  Go to the configuration of the planning area and ensure that the settings for time bucket generation are correct. This includes checking the time profile and the settings for the planning version.
  
  
  
  Use Transaction Codes:
  
  Use transaction codes like /SAPAPO/TSO (for time series objects) or /SAPAPO/SDP94 (for planning book) to review and manage time buckets.
