12:08, 11 December 2017 The {{UBIK}} WinX clients supports data replication mechanism so that users can create and maintain data more efficiently. For example, a user can quickly replicate a local branch and create multiple copies of it in other parts of the hierarchy.

On way to replicate data is through the copy & paste mechanism. A typical use case is as the following.
* Navigates to the branch that should be replicated;
* Brings up the bottom app bar and press {{key press|Copy}};
* Navigates to the destination where the branch should be replicated;
* Brings up the bottom app bar and press {{key press|Paste}}.
In principal, the usage is comparable to the copy & paste mechanisms in any other apps out there. However, there are some unique {{UBIK}} details worthing mentioning.
=== Regarding copy ===
When copying, an entire branch is involved. This includes
* The branch root object and all its local children (direct or indirect);
** [[QUERY|Queries]], [[SYSCLS_OFFLINE_QUERY|offline queries]] and all their children are ignored;
* Files of all (in)direct child documents. However, there are exceptions to this, namely
** if a file download fails;
** if the app is in offline mode.
* The data of the above mentioned objects: Display strings, user rights, etc.;
* The properties of the above mentioned objects: Their values, user rights, validations, etc.;
** All data users can interact with (e.g. values, validations) will only be copied if the [[MetaProperty]] allows.
The {{key press|Copy}} action is only available when the app initialization is complete and there is something to copy in the specified branch.
{{Hint|Validity of a copy: After triggering a copy, users can paste the same branch as many time as they want until
* either users log out;
* or another copy is triggered, which overrides the old copy;
* or the copied branch is no longer available (E.g. deleted)}}
=== Regarding paste ===
When pasting, an entirely independent copy of the specified branch is created and added as a child of the destination object.
The {{key press|Paste}} action is only available when
* The user has triggered a copy and it is still valid (see [[#Regarding_copy|Hint|Validity of a copy]]);
* And the destination object allows modification. In other words, it is not locked due to [[User_Rights|user rights]], [[MRO_Objects_(UBIK_WinX)#Organisational_Status|MRO status]] or [[SYSCLS_UNLOCK_BY_SCAN|scan status]];
* And the destination object allows the root of the copied branch as a child object. Namely the creation of the branch root's [[MetaClass]] should be allowed in the destination MetaClass. (See [[HowTo:Create_a_new_MetaClassScope|step 8]]).
