In Strobbo you can not only make Dimona declarations, but also Dimona updates and annulations.
You can make a Dimona update in the following way:
Choose in the menu for Schedule - Dimona.
Click on the left on the 'edit icon' (pencil) of the row you want to update.
Adjust the data of the Dimona and if necessary enter a 'Reason for change'.
Click on 'Update'.
Click at the end of the row on the 'send icon' (which turned black again after step 4)
Attention: it is possible to automate step 2-4 by linking our time entry clock to Dimona. More information on these automatical modifications in this article.
