• What is the cause and solution for SAP error message EC336 - All keys in this area have been assigned ?

  The SAP error message EC336, which states "All keys in this area have been assigned," typically occurs in the context of configuration or master data management within SAP. This error indicates that the system has run out of available keys for a specific area, such as a number range or a key assignment for a particular object.
  Cause:
  
  Exhausted Number Range: The most common cause is that the defined number range for a specific object (like a material, customer, vendor, etc.) has been completely utilized. This means that all possible keys (numbers) in that range have been assigned to existing records.

  Extend the Number Range:
  
  Go to the transaction code SNRO (Number Range Objects).
