  The SAP error message FINS_RECON738 with the description "COSS_BAK differs from COSS in attrib.- &1 &2 &3" typically relates to inconsistencies in the cost accounting data, specifically between the original cost object (COSS) and the backup cost object (COSS_BAK). This error often arises during reconciliation processes or when trying to post transactions that involve cost objects.
  Cause:
  
  Data Inconsistency: The primary cause of this error is that the attributes of the backup cost object (COSS_BAK) do not match those of the original cost object (COSS). This can happen due to manual changes, incorrect postings, or data corruption.

  Solution:
  
  Check Data Consistency: Use transaction codes like KSB1 (Cost Centers: Actual Line Items) or KOB1 (Order: Actual Line Items) to review the cost object data. Look for discrepancies between COSS and COSS_BAK.
  Reconcile Data: If discrepancies are found, you may need to reconcile the data. This could involve correcting the attributes of the cost objects or re-posting transactions to ensure consistency.
  Use Transaction Codes: You can use transaction codes like CKM3N (Display Material Cost Estimate) to analyze the cost estimates and see if there are any issues with the cost object attributes.
  Check Configuration: Review the configuration settings in the controlling module (CO) to ensure that everything is set up correctly. This includes checking the settings for cost elements, cost centers, and internal orders.
