• What is the cause and solution for SAP error message >U284 - Year of asset value date &1 for asset &2 not unique (reconcil. key &3) ?

  The SAP error message U284 indicates that there is a problem with the uniqueness of the asset value date for a specific asset in the context of reconciliation. This typically occurs when there are multiple entries for the same asset and value date combination, which is not allowed in the system.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that there are duplicate entries for the same asset and value date in the asset accounting tables. This can happen due to incorrect data entry, system errors, or issues during data migration.
  Reconciliation Key Conflicts: The reconciliation key mentioned in the error message may also have conflicting entries that are causing the uniqueness constraint to be violated.

  Check for Duplicates: 
  
  Use transaction codes like AS03 (Display Asset) or S_ALR_87011963 (Asset History Sheet) to review the asset records for duplicates.

  Review Reconciliation Keys:
