Why some options are missing in new product

Question

I am using Magento 1.7 and problem is this I have already some product in Magento admin when I edit any product then I find all options in inventory section but when I create new product then I couldn't find some options please see attached screenshots

This is following screenshot of product edit

Answer 1

this is because when you add product of screenshot then you have enabled managed stock from admin -> system -> configuration -> inventory -> product stock options -> manage stock set to YES but when you try to add new product then according to screenshot1 then this option is set to no please enable manage stock from admin for reenable all options

Answer 2

The difference between screenshot 1 and 2 is that in screenshot 1 the 'Manage stock' option is set to no following your global config.

If you set it to yes for that product by unselecting 'use config settings' or change the global default in the system > configuration > catalog > stock > settings productstock > manage stock you well get all the options in screenshot 2
