In Scheer PAS Designer you have two options to use data in your execution diagram:

  • Local data are only available for use within the current execution.
  • Persisted data are usable in all executions of the BPMN model.

On this page we explain how to persist data in the Designer and how to use the persisted data in your execution model.

How to Persist Data

If you want to persist the data of a variable, you need to perform the following steps:

Drag a type from your library and drop it in section Persisted on the execution pane.

For further information about variables on the execution pane see page Adding Variables.

By default a persisted variable gets assigned the name of its type.

You can change the name of persisted variables to one of your own choice by double-clicking the name. A list shows the names already in use.

Draw an object flow to assign a value to the persisted variable.

Persisted Variable with Default Value

A persisted variable can have a default value. If this is the case, you can find the field Default Value in the Attributes Panel.

Use the field if you want to change the initial value.

The default value can be changed for every deployed service because it is a setting on the BRIDGE.

See page xUML Service Settings in the BRIDGE User Guide to know more about xUML service settings in general and how you can change them.

Using Persisted Data

You can access all available persisted variables via section Persisted.

Click on the   icon to display the list of available persisted variables.

You can use the search to narrow down the content of the list.

Select the variable you need to use.


The variable is added to the execution pane.

Once a variable is defined as to be persisted, it is available in all executions throughout the BPMN model.
If you drag out the same type again, a second persisted variable is created that is independent of the first. A consecutive number is appended to the name automatically as variable names must be unique.

Now you can connect the persisted variable with the corresponding pin of the operation call.

This applies to input as well as to output pins.

Detailed information about the handling of pins can be found on page Adding Operation Calls.
