• What is the cause and solution for SAP error message RESCSU109 - &1: From-date of cost object SU cannot be before that of parent SU ?

  The SAP error message RESCSU109 indicates that there is a date inconsistency between a subordinate cost object (SU) and its parent cost object in the system. Specifically, the error states that the "From-date of cost object SU cannot be before that of parent SU." This typically occurs in the context of controlling and cost accounting modules where cost objects are structured hierarchically.
  Cause:
  
  Date Mismatch: The subordinate cost object's start date (From-date) is set earlier than the start date of its parent cost object. This violates the logical structure of cost objects, as a child cannot start before its parent.
  Incorrect Data Entry: During the creation or modification of cost objects, incorrect dates may have been entered.
  System Configuration Issues: There may be issues with how the cost objects are configured in the system, leading to inconsistencies.
  
  Solution:
  
  Check Dates: Review the From-date of both the subordinate and parent cost objects. Ensure that the From-date of the subordinate cost object is equal to or later than that of the parent.
  Modify Dates: If the subordinate cost object's From-date is incorrect, update it to a valid date that is on or after the parent cost object's From-date.
  Data Validation: Implement validation checks in your data entry processes to prevent this error from occurring in the future.
  Consult Documentation: Refer to SAP documentation or your organization's guidelines for managing cost objects to ensure compliance with best practices.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like KSB1 (Cost Centers: Actual Line Items) or KOB1 (Order: Actual Line Items) to review cost object details.
  Cost Object Hierarchy: Understanding the hierarchy of cost objects in your organization can help in managing and structuring them correctly.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message, as there may be updates or fixes provided by SAP.
  User Roles: Ensure that users have the appropriate roles and permissions to create or modify cost objects, as this can also lead to errors if not properly managed.
  
  By addressing the date inconsistency and ensuring proper data entry practices, you can resolve the RESCSU109 error and maintain the integrity of your cost object structures in SAP.
