there are two different types of Engineering Sales Orders (ECO) in ByD:

  • Single Date Orders

The difference is not explained in the help. What is the exact difference? Which different processes are triggered by that selection?

Thank you for your answer in advance

    Dear Klaus,

    An engineering change order (ECO) is an identifier that allows you to bundle changes to the content of input products in a variant. ECOs also allow you to specify a date on which changes become valid.

    There are two types of engineering change orders:

    • Single date orders

      When an engineering change order of type Single-date is created, a validity is automatically created with it. Only this validity is allowed. A Single-date engineering change order may be created and saved only when the valid-from date is set.

    • Single date validity orders

      You can create Single date validity orders if you have a requirement for changing validity parameters of a change order. This type of order can only be created with reference to an existing released or completed change order.

      You might need such a change for an isolated object or for some objects of one change order, especially for manufacturing purposes.

      The validity order inherits the validities from the referenced order. They can be changed, but cannot be deleted. You can change their status to Block.

      The validity order may be created only, if the referenced order has:

      • at least one released validity
      • at least one change group object reference with changed objects
      • the status Completed, if it is a normal engineering change order.

    You can use an ECO in one or more production BoM variant, as long as the input products associated with the ECO become valid at the same time. However, when you complete an ECO you prevent any further changes taking place in the variants associated with the ECO.

    For example, you have two variants with input products that are valid on the same date. However, you need to change input products in variant one while you need to start production on variant two. You should then use two separate ECOs even though both ECOs will have the same validity date.

    Kindly refer to the Production Model Document from the Help Center.

    Thanks & Regards,
