Configuring a Linear Call Sequence of Destination Systems

Procedure

  1. Create a new destination system of the type multiple call destination system.

    The Destination System Calls tab appears.

  2. To add a new step in the sequence of destination system calls table on the Destination System Calls tab, choose Add New Step. For more information, see Steps.
  3. In the newly created step, in the Destination System field, choose the destination system that you want to be called later.

    PCo displays the input and output variables of the selected destination system in the Assignment of Variables table.

  4. In the Description field, you can add a description for each individual step.
  5. Assign the variables of the multiple call destination system to the input and output variables of the destination system. You can do this in two ways:

    • In the lower screen area, in the Assignment of Variables table, choose Create New Variable to create a new multiple call destination system variable.

      The new multiple call destination system variable then receives the appropriate data type for the variable of the destination system. The system proposes the name of the destination system variable as the name of the multiple call destination system variable. You can subsequently change the name and data type of the multiple call destination system variable on the Variables tab.

    • Choose the Variables tab.

      You create an input, output, or local multiple call destination system variable here.

      Go back to the Destination System Calls tab and, in the Variable Name column, select, from the dropdown list, the multiple call destination system variable that you created earlier. Make sure that the data types of destination system and multiple call destination system variables are the same or can at least be converted into each other. If the data types are different, a data type conversion takes place at the runtime of the multiple call destination system, which can fail, depending on the current value of a variable.
