A data record in the MDM is a component or an order unit with a distinct order or article number and a corresponding description. In the MDM each data record exists only once.
If in the following activities are described that are relevant for data consistency and safety, this attention signal will alert the user to it.
In all structure views the data records assigned to the respective structure elements are listed in a table via the tab “Approved components“. The lines contain one complete data record each and the columns the corresponding data fields. The columns can be edited according to the well-known Excel functionality, data records can be sorted, selected and grouped via the data fields.
If a selection arrow appears at the right end of the field, the field contents can be viewed in a table stored there.
The field names for “Designation“, “Technical description“ and “Comments“ are highlighted selection buttons; a mouse-click on these buttons opens a window with entries in the selectable languages German, English, French and Hungarian.
The contentwise related data fields are summed up in the window „Component details“ in the individual tabs. The register contains the following data:
