colObjs = Session.Source.GetCollection(qOBJ)Using uow As IUnitOfWork = Session.StartUnitOfWork()For Each colElement As IEntity In colObjscolElement.PutValue("Property1", "TouchedByTestScript")uow.Put(colElement)Nextuow.Commit()End UsingWill result in the following Error:Trace: VI.Base.ViException: Values in read-only objects cannot be set.

Causa
The "GetCollection" function is missing a "EntityCollectionLoadType.Bulk " parameter.
This parameter is required for 'Unit Of Work' (UOW). This can also be referenced in One Identity Manager's OOTB Scripts which are using UOW.

colObjs = Session.Source.GetCollection(qOBJ,EntityCollectionLoadType.Bulk)Using uow As IUnitOfWork = Session.StartUnitOfWork()For Each colElement As IEntity In colObjscolElement.PutValue("Property1", "TouchedByTestScript")uow.Put(colElement)Nextuow.Commit()End Using
