• What is the cause and solution for SAP error message STREX187 - Unexpected attribute type for ABAP type N. Take &1 as in CompDescr Table. ?

  The SAP error message STREX187 indicates that there is an unexpected attribute type for an ABAP type N (which stands for numeric). This error typically arises when there is a mismatch between the expected data type and the actual data type being processed in the context of a data structure or table.
  Cause:
  
  Data Type Mismatch: The error usually occurs when the system expects a certain data type (like a character string or a different numeric type) but encounters an ABAP type N instead. This can happen in various scenarios, such as when reading from a database table or when processing data in an internal table.
  Incorrect Field Definition: The field in the CompDescr table may be defined with an incompatible data type or length that does not match the expected format for the operation being performed.
  Data Conversion Issues: If there are implicit or explicit conversions happening in the code, they may not be handled correctly, leading to this error.
  
  Solution:
  
  Check Data Types: Review the data types of the fields in the CompDescr table and ensure they match the expected types in your ABAP program. If a field is defined as type N, ensure that it is being used in a context that expects a numeric type.
  Adjust Field Definitions: If necessary, modify the field definitions in the database table or the ABAP program to ensure compatibility. For example, if a field is expected to be a character type, change its definition accordingly.
  Data Conversion: If you are performing any data conversions, ensure that they are done correctly. Use appropriate conversion functions or methods to convert between types safely.
  Debugging: Use the ABAP debugger to trace the execution of the program and identify where the error occurs. This can help you pinpoint the exact location and context of the type mismatch.
  Consult Documentation: Refer to SAP documentation or the ABAP programming guidelines for more information on handling data types and structures.
  
  Related Information:

  Database Table Definitions: Review the definitions of the database tables involved in your program to ensure that they are correctly defined and aligned with the ABAP data types.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context or solutions.
