• 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?

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</>.

CM_EHENV_CDEF_CHK026 - Details

• 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
