Scenario II – The Workflow
• For each trip:
– The applicant should fill a Meeting Application form
– Once submitted the application is handled over to the
respective Unit-Leader (or to the Directors for unit leaders)
– If the applicant is travelling for a project that does not belong
to his research unit the application has to be approved also
by the unit leader owner of the project
– Once returned from an approved trip, the applicant should fill
the Travel Refund form
– The Travel Refund form is verified by the Financial
Department
– In case of problem the applicant is required to make
correction till the final approval by the Financial Department
