Deletion of records in One Identity manager

Question

I am Using V8 version of One IM, I want to know that I have duplicate records in an outofthebox table and I want to delete those record from object layer so that it is transferred to all the child instances. 
 I figured out that marking xmarkedfordeletion as ready for deletion will do so,but how can I do so from object layer i.e changing the value of xmarkedfordeletion as ready for deletion?? 
 As this field is disabled to edit in object layer.

The basic principles of the inner workings of the Object Layer are explained here https://support.oneidentity.com/technical-documents/identity-manager/8.1.1/configuration-guide#TOPIC-1250313 
 Table 3: Lifecycle of an object mentions the method MarkForDeletion. 
 You will find a sample of it in the SDK on the product delivery "<OneIM>Modules\QBM\dvd\AddOn\SDK\ScriptSamples\03 Using database objects\17 Delete.vb" 
 We also have a complete video series around scripting and using the object layer on our official YouTube channel.
