• What is the cause and solution for SAP error message CM_EHFND_REQ043 - Input variables "&1" with data source type "&2" cannot be aggregated ?

  The SAP error message CM_EHFND_REQ043 indicates that there is an issue with the aggregation of input variables in a query or report. Specifically, it suggests that the input variable "&1" (which represents the name of the variable) with the data source type "&2" (which represents the type of data source) cannot be aggregated. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when working with queries that involve input variables.
  Cause:
  
  Incompatible Data Types: The input variable may be of a data type that does not support aggregation. For example, if the variable is a text or string type, it cannot be aggregated like numeric values.
  Aggregation Settings: The settings for the input variable may not allow for aggregation. This can happen if the variable is defined in a way that does not support aggregation in the context of the query.
  Data Source Type: The data source type may not support aggregation for the specific input variable. For instance, if the data source is a master data table, it may not be designed for aggregation.
  Query Design: The query design may have issues where the input variable is not properly linked to the data model, leading to aggregation problems.
  
  Solution:
  
  Check Data Type: Verify the data type of the input variable. If it is a non-aggregatable type (like a string), consider changing it to a numeric type if applicable.
  Review Variable Settings: Go to the variable settings in the query designer and check if the aggregation settings are correctly configured. Ensure that the variable is set to allow aggregation if it is supposed to be aggregated.
  Modify Query Design: Review the query design to ensure that the input variable is correctly linked to the data model. Make sure that the variable is used in a context that allows for aggregation.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the input variable and data source type you are using. This can provide insights into any limitations or requirements.
  Test with Different Data Sources: If possible, test the query with different data sources to see if the issue persists. This can help identify if the problem is specific to a certain data source type.
