In Scheer PAS Designer you have two options to use data in your UML activity 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 persited data in your execution model.

How to Persist Data

If you want to persist the data of an object, you need to perform the following steps:

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

For further information about objects on the execution canvas see page Adding Variables.

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

You can change the name of persisted objects 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 object.

Persisted Object with Default Value

A persisted object 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 objects via section Persisted. Click on the   icon to display the list of available persisted objects.

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

Select the object you need to use.


MultiExcerpt named persisted_object_added was not found -- Please check the page name and MultiExcerpt name used in the MultiExcerpt-Include macro

MultiExcerpt named second_persisted_object was not found -- Please check the page name and MultiExcerpt name used in the MultiExcerpt-Include macro

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

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.
