==== Locked objects ====
In some cases it might be useful to lock objects until the user varifies to be near to these objects. This can be done with the [[SYSCLS_UNLOCK_BY_SCAN]] classification ({{Version/AndroidSince|2.5.2}}). Instances of MetaClasses implementing this classification can only be edited after the object gets unlocked. The unlocking can currently happen by scanning any type of code (QR-Code, Barcode, ID-Marker, RFID, OCR) which is related to the according object. After a given amount certain period of time (default 15min) the object gets locked again.
Take care that objects which have the classified by [[SYSCLS_UNLOCK_BY_SCAN | SYSCLS UNLOCK BY SCAN]] classification also need the corresponding properties(e.g. QR-Code Propertyproperty) allowing such that the user is allowed to unlock these objects.<br/>If an object is locked, it is not possible to edit its properties. Furthermore , context actions like redlining or editing of documents, geo teach-in and deletion of the object on the server is not possible.Basically the locking is the same for all types of objects, except for work packages – unlocking them also means unlocking all underlying items (Tasks, Commissioning Checkschecks) as well.
