  The SAP error message IS_ADEC851 indicates that there is an issue with the input format for Work Breakdown Structure (WBS) elements in a particular transaction or process. Specifically, the error states that parentheses () and intervals (like ranges) are not allowed for WBS elements. This typically occurs when users attempt to enter WBS elements in a way that SAP does not accept, such as using parentheses to denote a range or grouping of WBS elements.
  Cause:
  
  Incorrect Input Format: The user may have entered WBS elements using parentheses or intervals, which is not supported by the system.
  Data Entry Error: There may be a typographical error in the WBS element input.
  System Configuration: The system may be configured to restrict certain formats for WBS elements.
  
  Solution:
  
  
  Check Input Format: Ensure that you are entering the WBS elements in the correct format. WBS elements should be entered as individual identifiers without any parentheses or intervals.
  
  For example, instead of entering (WBS1, WBS2), enter WBS1 and WBS2 separately.
  
  
  
  Review Documentation: Consult the SAP documentation or help files related to the specific transaction you are using to understand the expected input format for WBS elements.
  
  
  Use Valid WBS Elements: Make sure that the WBS elements you are trying to use are valid and exist in the system. You can check this in the WBS element master data.
  
  
  Error Handling: If you are using a program or report that generates WBS elements, ensure that it is not generating invalid formats. You may need to modify the program logic to handle WBS elements correctly.
  
  
  Consult with SAP Support: If the issue persists and you are unsure about the correct format or if there are system-specific configurations, consider reaching out to your SAP support team or consulting SAP Notes for further assistance.
  
  
  Related Information:
