Hi all,

how to fetch the value of my current fields as my default value when creating new records.

let say in my product model i have existing value of my fields which is field1 = 5 and field2 = 10 period Jan 1- 7, 2014.

what I want to achieve is on the next period dated Jan 8 - 14, 2014 or the next enter of the new inventory record for product1 else product2. I want to fetch previous value of field1 and field2 as the default value of my new field1 and field2.

currently i have custom product and inventory modules and 2 reserve fields in inventory module but Im stuck. I dont know how to implement. is very complicated because that 2 fields always been change, my Idea is to update that fields but I think I cant go back to my previous reports after created the new inventory records for the specific product because the value is changed. 

anybody here who can give Idea on how to do it and best way to implement this?.

This for custom weekly period monitoring inventory to my custom product

Thanks for reading
