  The SAP error message /IAM/CONFIG050 indicates that there is an issue with the use of certain special characters in a key field. Specifically, the error states that the characters *, +, %, and @ should not be used in the key specified by &1. This error typically arises in the context of configuration settings or when defining keys for certain objects in SAP Identity Management (IAM) or other related modules.
  Cause:
  The error is triggered when a user attempts to create or modify a key (such as a user ID, role name, or other identifiers) that includes one or more of the restricted special characters. These characters are often reserved for specific functions or operations within SAP and can lead to unexpected behavior or conflicts if used in key definitions.

  Identify the Key: Determine which key is causing the error by checking the message details where &1 is mentioned. This will give you the specific key that is problematic.

  Re-attempt the Operation: After modifying the key, try to save or execute the operation again to see if the error persists.
