• What is the cause and solution for SAP error message CO166 - Maintain a number range for order type & ?

  The SAP error message CO166, which states "Maintain a number range for order type &," typically occurs when you attempt to create a production order or a process order without having a defined number range for the specified order type. This is a common issue in SAP when the configuration for the order type is incomplete.
  Cause:
  The error is caused by the absence of a defined number range for the specific order type you are trying to use. Each order type in SAP requires a number range to ensure that each order can be uniquely identified. If this number range is not set up, the system cannot generate a new order number, leading to the error message.

  Save Your Changes:
  
  After maintaining the number range, save your changes.
