• Message class: CM_EHENV_CDEF -

• Message number: 009

• Message text: Input variable "&1" must be aggregated first

What causes this issue?

You want to create a calculation of a given data period. However, the
data periods of the input variables do not match the data period of the
calculation result.
For example, you want to create a caclulation of monthly data period but
the input variables (collected or calculated data) were originally set
to daily data periods.

System Response

The system cannot calculate input variables of given data periods to
calculation result of a different data period. The input variables must
be aggregated to the calculation result data period first.

How to fix this error?

To aggregate input variables of given data periods to other data periods
you can use any of the following aggregation functions:
<NP>SUM(<LB>INPUT_VARIABLE</>)</>
<NP>AVG(<LB>INPUT_VARIABLE</>)</>
<NP>MAX(<LB>INPUT_VARIABLE</>)</>
<NP>MIN(<LB>INPUT_VARIABLE</>)</>
<NP>COUNT(<LB>INPUT_VARIABLE</>)</>
<NP>AVGW(<LB>INPUT_VARIABLE</>; <LB>INPUT_VARIABLE</>)</>

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message CM_EHENV_CDEF009 - Input variable "&1" must be aggregated first ?

  The SAP error message CM_EHENV_CDEF009 indicates that an input variable in a query or report must be aggregated before it can be used in the context of the calculation or analysis you are attempting to perform. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA when working with queries that involve input variables.
  Cause:
  The error occurs when:
  
  An input variable is being used in a context where an aggregation is required, but the variable has not been aggregated.
  The query or calculation expects a single value (aggregated) but receives multiple values (non-aggregated).
  The input variable is defined in a way that does not allow for direct use without aggregation.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Input Variable Definition:
  
  Review the definition of the input variable in the query. Ensure that it is set up correctly and that it is intended to be used in an aggregated context.
  
  
  
  Modify the Query:
  
  If the input variable is being used in a calculated measure or a filter, ensure that it is aggregated properly. You can use aggregation functions like SUM, AVG, COUNT, etc., depending on your requirements.
  
  
  
  Adjust the Query Logic:
  
  If the input variable is part of a selection criteria, consider modifying the logic to ensure that it is aggregated before being used in the query.
  
  
  
  Use Aggregated Key Figures:
  
  If applicable, use aggregated key figures instead of the raw input variable. This can help in avoiding the error by ensuring that the data is already in an aggregated form.
  
  
  
  Test the Query:
  
  After making changes, test the query to ensure that it runs without errors and returns the expected results.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on input variables and aggregation in queries.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
  Query Designer: Use the Query Designer tool to visually inspect and modify the query structure, which can help in identifying where the aggregation is needed.
  
  By following these steps, you should be able to resolve the CM_EHENV_CDEF009 error and successfully run your query or report.
