• What is the cause and solution for SAP error message 5E621 - Hashed-type table not supported ?

  The SAP error message 5E621: Hashed-type table not supported typically occurs when there is an attempt to use a hashed table in a context where it is not supported. Hashed tables in ABAP are designed for fast access to data based on a unique key, but they have certain limitations regarding their usage in specific scenarios.
  Cause:
  
  
  Unsupported Operations: The error often arises when trying to perform operations that are not compatible with hashed tables, such as:
  
  Using hashed tables in certain types of function modules or methods.
  Attempting to pass hashed tables to certain ABAP statements or constructs that do not support them.
  
  
  
  Incorrect Table Type: The program may be incorrectly using a hashed table when a standard or sorted table would be more appropriate for the operation being performed.
  
  
  Solution:
  
  
  Change Table Type: If the hashed table is not necessary for your use case, consider changing the table type to a standard or sorted table. This can be done by modifying the declaration of the internal table in your ABAP code:
  DATA: lt_table TYPE STANDARD TABLE OF your_structure.
  
  
  Review Code Logic: Check the logic of your program to ensure that the use of a hashed table is appropriate. If you need to maintain unique keys and fast access, ensure that you are using the hashed table correctly.
  
  
  Use Appropriate Operations: If you must use a hashed table, ensure that you are only using operations that are supported for hashed tables, such as:
  
  Accessing entries using the key.
  Adding or deleting entries using the key.
  
  
  
  Debugging: If you are unsure where the error is occurring, use debugging tools to step through the code and identify the exact line or operation that triggers the error.
  
  
  Related Information:
  
  Documentation: Refer to the official SAP documentation for more details on internal tables and their types. Understanding the differences between standard, sorted, and hashed tables can help you choose the right type for your needs.
  Performance Considerations: While hashed tables provide fast access, they may not be suitable for all scenarios. Consider the performance implications of using different table types based on your specific use case.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates related to this error message.
  
  By following these steps, you should be able to resolve the error and ensure that your ABAP program functions as intended.
