  The SAP error message /SAPAPO/OM_TS291 Time series: Empty pattern chain not allowed typically occurs in the context of SAP Advanced Planning and Optimization (APO) when working with time series data. This error indicates that there is an issue with the pattern chain configuration for a time series, specifically that an empty pattern chain is not permitted.
  Cause:
  
  Empty Pattern Chain: The error is triggered when a time series is expected to have a defined pattern chain, but it is found to be empty. This can happen if the configuration for the time series does not include any valid patterns or if the patterns have been incorrectly defined or deleted.
  Incorrect Configuration: The configuration settings for the time series or the planning area may not be set up correctly, leading to the absence of a valid pattern chain.
  Data Issues: There may be issues with the underlying data that the time series is based on, such as missing or incomplete records.

  Ensure that a valid pattern chain is defined and that it is not empty. You can do this by navigating to the relevant planning area and checking the pattern definitions.

  If no patterns are defined, you will need to create and assign appropriate patterns to the time series. This can be done in the SAP APO system under the relevant configuration settings.
  
  
  
  Review Data:
  
  Check the underlying data for the time series to ensure that it is complete and correctly formatted. Look for any missing entries or inconsistencies that could lead to an empty pattern chain.
  
  
  
  Reprocess Data:
  
  If changes are made to the configuration or data, you may need to reprocess the time series data to ensure that the changes take effect.
