• What is the cause and solution for SAP error message RS_HCPR_MODEL143 - Complex aggregation level '&1' not supported as PartProvider ?

  The SAP error message RS_HCPR_MODEL143 indicates that a complex aggregation level is not supported as a PartProvider in the context of SAP BW (Business Warehouse) or SAP HANA modeling. This error typically arises when you are trying to use an aggregation level that has complex characteristics or hierarchies in a context where only simple aggregation levels are allowed.
  Cause:
  
  Complex Aggregation Level: The aggregation level you are trying to use has characteristics that are either too complex or not supported in the context of the PartProvider. This can include multiple hierarchies, calculated key figures, or other complex structures.
  Modeling Restrictions: Certain modeling scenarios in SAP BW or HANA have restrictions on the types of aggregation levels that can be used as PartProviders. This is often due to performance considerations or limitations in the underlying data model.
  
  Solution:
  
  Simplify the Aggregation Level: Review the characteristics and key figures in the aggregation level. Try to simplify it by removing complex hierarchies or calculated key figures that may not be supported.
  Use a Different Aggregation Level: If possible, switch to a simpler aggregation level that meets the requirements of the PartProvider. Ensure that the new aggregation level is compatible with the data model you are working with.
  Check Documentation: Refer to the SAP documentation for the specific version you are using to understand the limitations and supported configurations for PartProviders and aggregation levels.
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error or provide guidance on how to resolve it. SAP Notes often contain patches or workarounds for known issues.
