Mass Work Order creation for Model item Assembly & sub assemblies

Hi,

We have requirement of creating Work order for Model item assembly & sub assembly.

For example, User wants to automatically create Work orders for all the assembly and sub assembly of Model item.

Program should get all the assembly and sub assembly (all level) of particular Model item and create Work order for all ass/sub assembly.

How can we achieve this?

If anyone has the query for getting all the assembly and sub assembly components for Model item for WO creation, please provide.

any pointers will be helpful.
