• What is the cause and solution for SAP error message RESCSU018 - SU for costs posted directly to REC/RO, therefore apport. rule invalid ?

  The SAP error message RESCSU018 indicates that there is an issue with the allocation of costs in the context of a cost center or internal order. Specifically, it suggests that costs have been posted directly to a revenue account (REC/RO), which makes the allocation rule invalid. This typically occurs in the context of cost accounting and internal order management.
  Cause:
  
  Direct Posting to Revenue Accounts: The error arises when costs are directly posted to a revenue account instead of being allocated through the appropriate cost centers or internal orders.
  Invalid Allocation Rule: The allocation rule being used does not accommodate the direct posting to the revenue account, leading to inconsistencies in the cost allocation process.
  Configuration Issues: There may be configuration issues in the allocation structure or rules that do not align with the current postings.
  
  Solution:
  
  Review Posting Entries: Check the entries that have been posted directly to the revenue account. Ensure that costs should not have been posted directly to this account.
  Adjust Posting Method: If costs need to be allocated, consider using the appropriate cost center or internal order for posting instead of directly to the revenue account.
  Modify Allocation Rules: If necessary, review and modify the allocation rules in the configuration settings to ensure they can handle the types of postings being made.
  Repost Costs: If costs were incorrectly posted, you may need to reverse those postings and repost them correctly to the appropriate cost centers or internal orders.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific guidance on how to handle this error in your system context.
