Hi Guru's

Please let me know how to find the deleted line item in the component tab of maintenance order before saving.

for eg. The user creates the following line item in the component tab of the maintenance order.

Before saving he deletes the line item 20.

Item component qty

20 100003 20

Please let me know where exactly the deleted status is stored, before saving for the line item
