SAP Error Message - Details

• Message type: E = Error

• Message class: CM_EHENV_CDEF_CHK -

• Message number: 026

• Message text: Type of input variable "&1" does not match the expected data source type

What causes this issue?

You created a calculation setup using an equation from a compliance
requirement. However, an input variable of the expression is not defined
correctly in the setup.

System Response

The data source type defined for the input variable in the
<ZH>calculation setup</> does not match to the data source type
pre-defined in the compliance requirement <ZH>equation</>.

How to fix this error?

Make sure that the data source types that you specify for the input
variables in the <ZH>calculation setup</> correspond to the data source
types that are defined for these variables in the compliance requirement
<ZH>equation</>.

• What is the cause and solution for SAP error message CM_EHENV_CDEF_CHK026 - Type of input variable "&1" does not match the expected data source type ?

  The SAP error message CM_EHENV_CDEF_CHK026 indicates that there is a mismatch between the type of an input variable and the expected data source type in a context, typically in the context of a data model or a calculation view in SAP HANA or SAP BW.
  Cause:
  This error usually occurs due to one of the following reasons:
  
  Data Type Mismatch: The input variable is defined with a specific data type (e.g., integer, string, date) that does not match the expected data type of the data source it is being compared or used with.
  Incorrect Variable Definition: The variable might be incorrectly defined in the context of the data model, leading to a mismatch.
  Changes in Data Source: If the underlying data source has been modified (e.g., changes in the structure or data types), it may lead to this error when the input variable is still referencing the old structure.
  Inconsistent Metadata: There may be inconsistencies in the metadata definitions between the input variable and the data source.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Input Variable Definition:
  
  Go to the definition of the input variable that is causing the error.
  Verify the data type of the input variable and ensure it matches the expected data type of the data source.
  
  
  
  Review Data Source Structure:
  
  Check the structure of the data source that the input variable is referencing.
  Ensure that the data types in the data source are as expected and have not changed.
  
  
  
  Adjust Data Types:
  
  If there is a mismatch, adjust the data type of the input variable to match the expected data type of the data source.
  If necessary, create a new input variable with the correct data type.
  
  
  
  Rebuild or Refresh:
  
  If changes were made to the data source or input variable, consider rebuilding or refreshing the data model to ensure that all components are synchronized.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, test the data model or calculation view to ensure that the error no longer occurs.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on input variables and data types in the context of your specific SAP environment (e.g., SAP BW, SAP HANA).
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and to find additional solutions or workarounds.
  Debugging Tools: Utilize SAP debugging tools to trace the execution and identify where the mismatch occurs in the data flow.
  
  By following these steps, you should be able to identify and resolve the cause of the CM_EHENV_CDEF_CHK026 error in your SAP environment.
