  The SAP error message RS_B4H_PREPARE_APD055 indicates that there is an issue with the aggregation type being used in a calculation or query in the context of HCPR (HANA Calculation and Planning Runtime). Specifically, it suggests that the aggregation type specified for a particular field is not supported.
  Cause:
  
  Unsupported Aggregation Type: The error typically arises when the aggregation type specified for a field in a calculation view or query is not compatible with the HANA Calculation and Planning Runtime. This can happen if you are trying to use an aggregation method that is not allowed for the data type or context of the field.
  Field Configuration: The field in question may not be configured correctly in the underlying data model, or it may not support the specified aggregation type due to its characteristics (e.g., it might be a non-aggregatable field).
  Data Model Issues: There could be issues in the data model design, such as incorrect joins or relationships that lead to unsupported aggregations.
  
  Solution:
  
  Check Aggregation Type: Review the aggregation type being used for the field in question. Ensure that it is one of the supported types for the HANA Calculation and Planning Runtime. Common supported types include SUM, COUNT, AVG, etc.
  Modify Field Configuration: If the field is not meant to be aggregated, consider changing its configuration to avoid aggregation or use a different field that supports the desired aggregation.
  Review Data Model: Examine the data model for any inconsistencies or errors. Ensure that the field is correctly defined and that the relationships between tables are properly set up.
  Consult Documentation: Refer to the SAP HANA documentation for a list of supported aggregation types and any specific limitations related to the HCPR.
  Testing: After making changes, test the query or calculation view again to ensure that the error is resolved.
