• What is the cause and solution for SAP error message WZ150 - *** 150 - 199 Reserved for test utilities ?

  SAP Error Message:
  
  WZ150 *** 150 - 199 Reserved for test utilities
  
  Cause:
  The message WZ150 with the text 150 - 199 Reserved for test utilities indicates that the message number range from 150 to 199 in the message class WZ is reserved internally by SAP for test or system utilities. This means that these message numbers are not intended for regular application use or custom messages.
  If you encounter this message during development or runtime, it usually means that:
  
  Your program or a custom development is trying to trigger or use a message number within the reserved range (150-199) of the message class WZ.
  The system is warning you that these message numbers are reserved and should not be used for normal application messages.
  It might also appear if a test or utility program is running that intentionally uses these reserved messages.
  
  
  Solution:
  
  Avoid using message numbers 150 to 199 in message class WZ for your custom or application messages.
  If you are developing or maintaining code, choose message numbers outside the reserved range (e.g., below 150 or above 199) for your messages.
  If this message appears unexpectedly during runtime, check if any custom code or user-exits are incorrectly calling or raising messages in this reserved range.
  If the message appears during testing or system utilities, it can generally be ignored as it is part of SAP's internal test framework.
  
  
  Related Information:
  
  SAP message classes often reserve certain message number ranges for internal use or testing.
  The message class WZ is typically related to workflow or system utilities, but the exact usage depends on the SAP module.
  To view or maintain message classes and messages, use transaction SE91.
  For custom messages, always use your own message class and avoid reserved ranges.
  If you need to define new messages, create your own message class and assign message numbers starting from 001 upwards, avoiding any reserved ranges documented by SAP.
