Can not create a goal diagram using Diagram Manager in SSM

When creating a strategy plan using Diagram Manager in SSM, the diagram is not saved.

The steps done are:

1. In SAP SSM Administrator Interface acces to Set Strategy Defaults and selected the context.

2. In Create or edit Goal Diagrams I clik on Edit Gola diagram 1 and the Diagram Manager runs.

3. The auto-layout is showed then I save and I publish the diagram. Then I exit the Diagram Manager.

4. In SAP SSM Administrator > Set Strategy Defaults I click on Save button, it shows the message window "Update complete" but the Publish date column shows "Not published" message instead of the actual date.

Good advice would be welcomed

Thank you very much
