• What is the cause and solution for SAP error message WW202 - Error allocating object to class SY-SUBRC = & ?

  The SAP error message WW202, which states "Error allocating object to class SY-SUBRC = &", typically indicates that there is an issue with memory allocation or object instantiation in the ABAP program. The SY-SUBRC variable is used in ABAP to indicate the return code of the last operation, and a non-zero value usually signifies an error.
  Causes:
  
  Memory Limitations: The system may be running low on memory, which can prevent the allocation of new objects.
  Incorrect Object Type: The program may be trying to instantiate an object of a class that does not exist or is not properly defined.
  Configuration Issues: There may be issues with the configuration of the SAP system that affect object allocation.
  Code Errors: There could be bugs or logical errors in the ABAP code that lead to this error.
  
  Solutions:
  
  Check Memory Usage: Monitor the memory usage of the SAP system. If the system is low on memory, consider increasing the memory allocation or optimizing the code to use less memory.
  Review Code: Look at the ABAP code where the error occurs. Ensure that the class being instantiated is correctly defined and that the instantiation logic is correct.
  Check Object Definitions: Verify that the class and its methods are properly defined in the system. Ensure that there are no typos or misconfigurations.
  Debugging: Use the ABAP debugger to step through the code and identify the exact point of failure. Check the value of SY-SUBRC to understand what went wrong.
  System Configuration: Review the system configuration settings related to memory management and object allocation. Consult with your Basis team if necessary.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide patches or updates.
  
  Related Information:
