• What is the cause and solution for SAP error message /STMC/CR_LOG196 - &1: Different data types cannot be compared ?

  The SAP error message /STMC/CR_LOG196 &1: Different data types cannot be compared typically occurs in the context of data processing or reporting, particularly when there is an attempt to compare or evaluate fields of different data types. This can happen in various scenarios, such as during data extraction, transformation, or when running reports.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that the system is trying to compare two fields that have incompatible data types. For example, comparing a string with a numeric value or a date with a string.
  Incorrect Field Mapping: In data transformation processes, if fields are incorrectly mapped or if the data types are not aligned, this error can occur.
  Database Views or Queries: If a query or view is constructed that attempts to compare different data types, it can lead to this error.
  Custom Code: If there is custom ABAP code or logic that performs comparisons without ensuring data type compatibility, this error may arise.
  
  Solution:
  
  Check Data Types: Review the data types of the fields being compared. Ensure that they are compatible. For example, if you are comparing a numeric field with a string, convert the string to a numeric type or vice versa.
  Modify Queries or Views: If the error occurs in a query or view, modify it to ensure that the fields being compared are of the same data type.
  Data Transformation Logic: If you are using ETL (Extract, Transform, Load) processes, ensure that the transformation logic correctly handles data type conversions.
  Debug Custom Code: If the error is coming from custom ABAP code, debug the code to identify where the comparison is happening and ensure that the data types are compatible.
  Use Type Casting: In some cases, you can use type casting functions to convert one data type to another before performing the comparison.
