In the ITEMS section, I have listed my Raw materials (Say RM1 - For Mild Steel Pipes). 

Once I raise a PO to buy these Raw materials, and close the PO by raising a Bill and recording a Payment, the Raw material gets updated in my Stock-Inventory.

RM1 - Mild Steel Pipe 6meter in Length - Initial Stock count - 10Nos

WIP1 - Mild Steel Pipe 6meter in Length with Drilled holes - 0 Nos

Now I perform a value addition on 3  Nos (cutting, drilling, notching etc), which will convert the RM1 to WIP1 (Work in Progress-1).

After drilling holes in 3 Pipes, my updated Stock count -

RM1 - Mild Steel Pipe 6meter in Length - UPDATED Stock count - 7 Nos

WIP1 - Mild Steel Pipe 6meter in Length with Drilled holes - 3 Nos

I wish to generate a Job Work task (or any other event) on Zoho Inventory, which will reduce my RM1 count, and increase my WIP1 count in the system.

RM1 -> Job Work -> WIP1

Please suggest how I can achieve the same on Zoho inventory.
