• What is the cause and solution for SAP error message TAN_TCC1052 - Monotone convex interpolation is not permitted for DCS-based curves ?

  The SAP error message TAN_TCC1052, which states "Monotone convex interpolation is not permitted for DCS-based curves," typically occurs in the context of SAP's Advanced Planning and Optimization (APO) or similar modules where demand planning and forecasting are involved. This error is related to the interpolation method used for demand curves, particularly when dealing with DCS (Demand Chain Solutions) based curves.
  Cause:
  The error arises when the system attempts to apply a monotone convex interpolation method to a DCS-based curve, which is not allowed. Monotone convex interpolation is a method that ensures that the interpolated values do not create any local maxima or minima, which is not compatible with the characteristics of DCS-based curves. DCS curves are often used for more complex demand patterns and may not adhere to the constraints required for monotone convex interpolation.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Curve Type: Verify the type of curve you are using. If you are using a DCS-based curve, ensure that the interpolation method is appropriate for that curve type. You may need to switch to a different interpolation method that is compatible with DCS curves.
  
  
  Adjust Interpolation Settings: In the settings for the demand planning or forecasting model, look for options related to interpolation methods. Change the interpolation method to one that is suitable for DCS curves, such as linear interpolation or another method that does not impose monotonicity constraints.
  
  
  Review Data: Ensure that the data being used to generate the curve is valid and does not contain anomalies that could lead to the need for monotone convex interpolation. Clean up any outliers or incorrect data points.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on the types of curves and interpolation methods supported in your version of SAP. This can provide insights into best practices and configurations.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for further assistance. They may have additional insights or patches that can resolve the issue.
  
  
  Related Information:
  
  SAP APO: Advanced Planning and Optimization is a tool used for supply chain management, and understanding its functionalities can help in troubleshooting related errors.
  Interpolation Methods: Familiarize yourself with different interpolation methods and their applicability to various types of data curves.
  DCS Curves: Understanding the characteristics and use cases of DCS curves can help in making informed decisions about data modeling and forecasting.
  
  By following these steps, you should be able to address the TAN_TCC1052 error effectively.
