RG119 - Overview

• Message type: E = Error

• Message class: RG - BW generation tool: Messages

• Message number: 119

• Message text: Hash algorithm '&1' is not supported for generating UUID

What causes this issue?

To convert an application key into a hash-based UUID (Universally Unique
Identifier), only the hash algorithms '&V2&' and '&V3&' are supported.

System Response

The call of function module RSS_UNIQUE_CONVERT_TO_ID25 was terminated
with exception INVALID_INPUT.

How to fix this error?

Pass a valid hash algorithm in parameter I_HASH_ALGORITHM when you call
function module RSS_UNIQUE_CONVERT_TO ID25.

• What is the cause and solution for SAP error message RG119 - Hash algorithm '&1' is not supported for generating UUID ?

  The SAP error message RG119 indicates that the hash algorithm specified for generating a UUID (Universally Unique Identifier) is not supported. This error typically arises when the system is configured to use a hash algorithm that is either deprecated or not available in the current environment.
  
  Cause:
  
  Unsupported Hash Algorithm: The specified hash algorithm (e.g., SHA-1, SHA-256) is not supported by the version of SAP you are using or is not available in the underlying Java or ABAP environment.
  
  Configuration Issues: The system may be misconfigured, leading to the use of an unsupported algorithm.
  Missing Cryptographic Libraries: The necessary cryptographic libraries that support the specified hash algorithm may not be installed or properly configured.
  
  
  Solution:
  
  Check Supported Algorithms: Verify the list of supported hash algorithms for your version of SAP. You can refer to the SAP documentation or the system's configuration settings.
  Update Configuration: If the hash algorithm is incorrectly specified in the configuration, update it to
