• What is the cause and solution for SAP error message CKMLMV354 - Product cost collector &1 already exists ?

  The SAP error message CKMLMV354 indicates that a product cost collector (PCC) with the specified identifier already exists in the system. This error typically occurs when you attempt to create a new product cost collector for a material or production order that already has an existing collector.
  Cause:
  
  Duplicate Entry: The most common cause is that a product cost collector with the same identifier has already been created for the material or production order.
  Incorrect Data Entry: There may be a mistake in the data entry process, leading to an attempt to create a collector that already exists.
  System Configuration: In some cases, system settings or configurations may lead to unexpected behavior, causing the system to think a collector already exists.
  
  Solution:
  
  
  Check Existing Collectors: 
  
  Use transaction code CKMLCP (Product Cost Collector) or CKMLMV (Product Cost Collector Overview) to check if a product cost collector already exists for the specified material or order.
