• What is the cause and solution for SAP error message 00671 - Internal session terminated with a runtime error & (see ST22) ?

  The SAP error message "00671 Internal session terminated with a runtime error" typically indicates that an ABAP program has encountered a runtime error, which has caused the session to terminate unexpectedly. This can happen for various reasons, including programming errors, resource issues, or data inconsistencies.
  Causes:
  
  Programming Errors: Bugs in the ABAP code, such as accessing null references, division by zero, or incorrect data types.
  Resource Limitations: Insufficient memory or other system resources can lead to runtime errors.
  Data Inconsistencies: Issues with the data being processed, such as missing or corrupted data.
  Configuration Issues: Incorrect settings in the SAP system or in the specific application module.
  Transport Issues: Problems with transported objects that may not have been properly adjusted in the target system.
  
  Solution:
  
  
  Check ST22: The first step is to check transaction ST22 (Dump Analysis) to get detailed information about the runtime error. This transaction provides a list of dumps that have occurred, along with their details.
  
  Look for the specific dump related to the error message.
  Analyze the short dump to identify the cause, which will include the error type, the program name, and the line number where the error occurred.
  
  
  
  Debugging: If you have access to the ABAP code, you can debug the program to identify the exact point of failure. Use transaction SE80 or SE38 to access the program and set breakpoints.
  
  
  Review Code: If the error is due to a programming issue, review the code for potential bugs. Common areas to check include:
  
  Data declarations and types.
  Logic that could lead to null references or invalid operations.
  Loops and internal tables that may not be handled correctly.
  
  
  
  Check System Resources: Ensure that the system has adequate resources (memory, CPU) to handle the processes being executed.
  
  
  Data Validation: Validate the data being processed to ensure there are no inconsistencies or corruption.
  
  
  Consult SAP Notes: Search the SAP Support Portal for any relevant SAP Notes that may address the specific error or provide patches.
  
  
  Contact SAP Support: If the issue persists and cannot be resolved internally, consider reaching out to SAP Support for assistance.
