• What is the cause and solution for SAP error message AJ666 - DPC-ESTB: Original category of current period is not unique ?

  The SAP error message AJ666, which states "DPC-ESTB: Original category of current period is not unique," typically occurs in the context of the SAP Controlling (CO) module, particularly when dealing with actual or planned data in the context of cost center accounting or internal orders.
  Cause:
  This error usually arises when there are multiple entries for the same category in the current period, which leads to ambiguity in determining which entry should be used for processing.

  Adjust Entries: If duplicates are found, you may need to adjust or delete the unnecessary entries. Ensure that each category has a unique entry for the current period.
  
  
  Review Configuration: Check the configuration settings in the controlling area to ensure that the settings for categories and periods are correctly defined. This includes verifying that the settings for the original categories are appropriate and do not allow for duplicates.
