Container OperationLocate this document in the navigation structure

Use

You use a container operation () to set a value for a target container element at runtime (see also: Defining the Data of a Process in Containers ). The target container element and the assigned value must have the same data type. To specify the value, use the expression editor (see also: Using the Expression Editor .

You can:

  • Assign

    Assigns a value to a single line or multi-line container element. This value overwrites the previous value. You can use this container operation to count a counter variable, for example.

  • Append

    Appends a value to a multiline container element. For example, you can use this container operation to append individual messages to multiline container elements when gathering messages together.

Note

You cannot change a message by using a container operation. To change a message, use a transformation step .
