How can i remove some fields of product edit page in vendor cpanel?

From version 1.1.0.2 you can customize the add product form easily: Customize the Add product form of vendor

Edit this file: app/code/local/VES/VendorsProduct/etc/config.xml

Search this code

<product_attribute_restriction>
    <vendor_id />
    <approval />
    <group_price />
    <tier_price />
    <msrp_enabled />
    <msrp_display_actual_price_type />
    <enable_googlecheckout />
    <group_price />
    <sku />
    <!-- Put the attribute which you want to remove here -->
</product_attribute_restriction>

Add the attribute which you want to remove to above code.

You can also create a custom module and add a code like the above code to your config.xml

This solution works with Marketplace V1.0.0.6 or newer
