Maintenance events can be connected to one structure or to many.
Therefore QGEP uses a intermediary RE_table to model the n:m relationship (re_maintenance_event_wastewater_structure)
To avoid an error when adding a new Maintenance Event, you have to enable Buffered Transaction Groups in menu Project > Transaction mode
With the Identify Features tool you can select wastewater_structures or reaches by selecting their corresponding layer (vw_qgep_wastewater_structure or vw_qgep_reach).
The respective form will open. Change to the Maintenance tab.
Create a new maintenance event with the Add child feature button.
Edit the new record in the vw_qgep_maintenance form, then click OK

Attention
There is only the record in the RE-table deleted. The maintenance event record himself is not deleted and can by linked with other wastewater structures.
There is in the moment no tool to create or to link a maintenance event to a selection of reaches or wastewater structures. If you open the form in multi edit mode, the Maintenance tab is empty.
Multi edit with linked tables is not implemented in QGIS.
