• What is the cause and solution for SAP error message WE245 - Prefix & ('&') is defined in Customizing ?

  SAP Error Message:
  WE245 - Prefix & ('&') is defined in Customizing
  
  
  Cause:
  This error occurs when the system detects that a prefix containing the ampersand character (&) is defined in the IDoc number range or message type customizing. The ampersand (&) is a special character in SAP used as a placeholder or variable indicator in various contexts, and its presence in prefixes can cause conflicts or unexpected behavior during IDoc processing.
  Typically, this happens if in the IDoc number range intervals or message type configuration, a prefix with & is maintained, which is not allowed.
  
  Explanation:
  
  In SAP, IDoc numbers can have prefixes defined in customizing to distinguish different IDoc types or sources.
  The prefix should be alphanumeric and should not contain special characters like &.
  The & character is reserved for variable substitution in SAP scripts and other areas, so its use in prefixes is prohibited.
  
  
  
  Solution:
  
  
  Check the IDoc Number Range Intervals:
  
  Go to transaction WE30 or WE21
