Hi ,

     I need to access the relational table created by many to many field, is it possible to access the table?

Thanks in advance......

What is your exact aim? Whenever you call that field you will get the appropriate values, like the other fields.

Do you mean the id field of that relational table? Why do you need that? As soon as you will call that many2many field there will be browse record of the field against which you have created the relation.

Sorry, but I don't think that you need to know the "ID"(actual ID field) field of that relational table. You can have customer and product as many2many, what is the need? Lets say you got the ID, how and where do you use that ID field. If possible post your code here.

So yes, as soon as you will do "partner_id.products", (products is your field name) it will give you the browse records of only all those categories which are linked to that particular customer. Try this.

That is what I am saying once you will have the browse record of 'sale.order', you can get the product categories of customers as 'br_sale_order.partner_id.products'. Where do you want to match? With what you want to match it? You will only those product categories which are there in that particular customer not more than that.

When ever you will browse the sale.order model, you can use like this let's say your browse record is "br_sale_order", than you can use "br_sale_order.partner_id.products", which will give you the browse records of "product.category" model and you can iterate the loop on it.
