This page explains how to add, edit and delete complementary activities for Mobility of youth workers (KA153-YOU) projects in My projects.

Complementary Activities are side activities adding a value to the project and contributing to increase its impact (e.g. seminars, conferences, coaching) and are encoded under the specific tab in Mobility Tool+.

The indirect costs of complementary activities cannot be higher than 7% of the direct costs. The grant covers up to 80% of the total costs (direct + indirect), and the amount of the total eligible cost cannot be higher than 10% of the project costs. The total eligible amount is displayed in the budget tab and is added to the Final Beneficiary Report.

Take note

Questions or fields may vary depending on the action type of you project. Please read the onscreen information carefully to complete the relevant fields and sections.



  • Only the contact person of the beneficiary organisation with edit rights on the project is able to perform these actions.
  • A grant agreement has been signed for the project, and it is visible in My projects.
  • To update the project it must have the status Project Ongoing.

Detailed Steps

1. Add a complementary activity

1.1. Access "Complementary Activities" in the Content menu

In your project, click on Complementary Activities in the Content menu.

The complementary activities screen is displayed. All the complementary activities that you add will be shown here. Initially, the complementary activity list is empty.

1.2.  Click on "Create" 

Click on the Create button at the top right of the list to open the Complementary Activity details screen.


1.3. Fill in the complementary activity details

In the details screen fill in the fields as required. Mandatory fields are marked with a red asterisk (*).

Note the following:

  1. The Complementary activity ID is generated automatically as you add each complementary activity and is unique for each activity.
  2. The indirect cost you enter must be at most 7% of the direct cost. Otherwise an error message is displayed and you must adjust this value accordingly.
  3. The total cost for the complementary activity is calculated automatically, as 80% of the sum of the direct and the indirect costs. This value cannot be changed manually. If the total cost related to all complementary activities added in the project exceeds 10% of the total project costs, an error message is displayed under the field, and you must adjust the values for direct and/or indirect costs.
  4. The amounts entered in the budget fields can have one decimal at most, e.g. "100.4"

1.4. Click "Save"

Once you have filled in all the mandatory information, the Save button at the bottom right corner of the screen becomes available. Click the Save button to save the complementary activity details for your project.
A success message is displayed, and you are redirected to the Complementary Activities list, where the newly added activity is now listed.
