• What is the cause and solution for SAP error message /SAPAPO/SDP226 - Function is not possible; periodicty must be unique, and 'T', 'W' or 'M' ?

  The SAP error message /SAPAPO/SDP226 Function is not possible; periodicity must be unique, and 'T', 'W' or 'M' typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with planning books or data views that involve time series data.
  Cause:
  This error indicates that there is an issue with the periodicity settings in your planning book or data view. The periodicity must be set to one of the following values:
  
  'T' for daily (time-based)
  'W' for weekly
  'M' for monthly
  
  The error arises when:
  
  The periodicity is not set to one of the allowed values.
  There are multiple periodicities defined for the same planning object, which leads to ambiguity.

  Solution:

  Check Planning Book Configuration:
  
  Go to the planning book configuration in the SAP APO system.

  Review Data View Settings:
  
  If you are using a data view, check its settings to ensure that the periodicity is consistent with the planning book.
  Ensure that the data view is not trying to combine different periodicities.
  
  
  
  Adjust Time Series Data:
  
  If you are working with time series data, ensure that the data is structured correctly according to the defined periodicity.
  Check for any data entries that may not conform to the expected periodicity.
  
  
  
  Recreate Planning Book or Data View:
  
  If the issue persists, consider recreating the planning book or data view from scratch, ensuring that you set the periodicity correctly from the beginning.
