Depends.

I know that if B and C are pseudo (not real), no work order will be  
created.  We use this for assemblies that are logically grouped  
(handle assembly, side panel) but are assembled on line.  We don't  
actually build, put in inventory, pull from inventory, then attach a  
handle assembly.  This may be similar for you.  Do you have completed  
Bs and Cs sitting around?

My opinion is that the B and C should probably be added as lines on  
the original work order, so you can keep them together, but I don't  
think this happens currently.  If you want, please let me know any  
other details or options, I'll try to add this in.

Depends.
If you're not using workflow, you don't get much choice of status, the  
options are:
- Pending: Entered, but no start date
- Scheduled: Start date entered
- Completed: Finished production
This is because without workflow, pERP cannot track your work order  
through your production process.  It all happens at once, "In  
production" lasts about 0.2s as all inventory is consumed and the work  
order is completed.  This works fine for small shops, where the  
overhead of keeping the status up to date isn't worth it.

If you are using workflow, see this reference:
http://www.projecterp.org/mediawiki/index.php/Setting_Up_Workflow
After you're set up, you can move your work orders through the process  
with the 'Move To' dropdown on the Work Order List.
I hope to get a more automated solution (line scanners) done soonish.
