The import of model elements is only possible, if a global lock is set. This can be achieved by the Lock All For Editing option. Please refer to the section Locking all Lockable Elements of the chapter Locking and Unlocking Elements for detailed information on this option.
In case you try to import model elements without owning a global lock on the target model, the following error message requesting to obtain a global lock first is displayed:

If a process definition is not locked for editing, no elements pertaining to process definitions like activities, triggers, transitions or data paths, can be added, removed or edited in this process definition.
Process diagrams are not editable, if the parent process definition is not locked. You can open them in read-only mode, which means:
A diagram in locked state might contain model elements like participants, applications or data, that can be changed independently. In case these elements are locked for editing, they can be edited from within the diagram, like opening the property dialog, renaming and deleting, but their symbols have the same restrictions as all element symbols in a non-editable diagram.
In case you try to edit a model element pertaining to the process definition or another element, which is not in locked state, a message dialog opens to notify that the element has to be locked first:
Figure: Message Dialog requesting Lock on Element.
In case a model diagram is not locked for editing, you can open it in read-only mode, as described for process diagrams.
The behavior of the contained symbols pertaining to model elements is the same as described for process diagrams.
Property dialogs of model elements of a model in Concurrency Management Mode are displaying all control fields in read-only mode. To edit content, a button Lock for Editing is provided at the bottom of the dialog. Clicking this button will lock the corresponding model element or, if the model element to be edited is only part of a lockable element, its containing element.

In case the lock attempt fails, an according error dialog opens and all controls stay in readonly mode.

Property dialogs of elements pertaining to a process definition are not editable if the parent process definition is not locked.
In case model elements are copied to a model in concurrency mode, the new elements will be displayed as newly added elements in the Outline view and provided to be committed in the commit dialog. In case a diagram or process definition, where a copied element should be pasted, is not locked, a warning dialog opens to indicate that the target element has to be locked first.

Direct editing of symbol names, like using the F2 short key or a mouse click on the name, requires a lock for editing on the according element or a lock on the according process definition accordingly. Otherwise a message dialog opens to inform that a lock has to be achieved before.

If new lockable model elements are created, their according lock file will not be created and submitted immediately, this is done on commit. New elements pertaining to a parent node, for example a process definition, can only be created, if the parent node is locked for editing.
For all lockable element, the newly created element is indicated as new with an overlay icon displaying a plus sign in the right upper corner of the element icon:
Figure: Icon indicating an added model element.
A confirmation dialog open when deleting a lockable element:
Figure: Deletion Confirmation Dialog
To delete any element a lock must be obtained before the user can delete the element. Deleting activities or other elements pertaining to a process definition, requires a lock of the according process definition. In case the parent process definition is not locked, the Delete option is not available.
In case an element is deleted having symbols in a diagram, that is locked for editing, the symbols are also deleted. If the according diagram is not locked for editing, the symbols are not deleted, but replaced with undefined symbols.

In case a user deletes a lockable model element and commits this change, this is indicated in the appropriate model element in the Outline view to other users by an overlay icon representing a cross.

In the Outline view, the lock state of model elements are indicated in the lower right corner of the model elements icon. The following states are possible:
In case a model element is shared with the repository, but not locked, the following overlay icon indicates this state:
Figure: Shared Mode
In case a model element is locked for editing, a checkmark icon indicates that state:
Figure: Locked State
In case a model element is locked by another user, the following icon is indicating this state:
Figure: Locked by another User
Additionally the name of the user who locked this element is added to the right side of the model element name, e.g.:
Figure: Name of the User who locked the Element.
In case an already existing model element is imported from an external model resource, the original version will be replaced. A confirmation dialog opens, where you can choose to replace the existing element or to reuse the element in the model:
Figure: Replacement Dialog
The corresponding model elements have to be locked for editing before this action. Otherwise, an according error message requesting to lock the model elements before the import is displayed.
Please refer to the chapter External Model Resources for general information on working with external model resources.
