How to lock objects in a workbench request

Hi All,

I am creating certain objects in the system in my own program. These objects are WD components, programs and FM's. The user can run this application and create his own objects. The question is, while creating an object, when the user is prompted to enter a package name and a transport request number, how do I make sure that the object that is getting created gets locked under the particular workbench request?

Regards
