Hi,

You can replace existing access right in your custom module as follows:

Suppose if you have access right in account module as this:

access_product_product_account_user,product.product.account.user,product.model_product_product,group_account_user,1,0,0,0

and if you need to change this in your module, you can write as follows:

account.access_product_product_account_user,product.product.account.user,product.model_product_product,account.group_account_user,1,0,1,1

Just replace id with original_module_name.id .

Thanks
