Ah, then this is the (Trytoin internal) ID.
Then we need an additional field “customer’s Blanket Order Number” which contains the number (or string) the customer gives for this Blanket Order, and which has to be printed on the documents, resp. transmitted in the EDI message.

It is not the ID, I’m talking about number.
Anyway this is very minor detail that has no point to be discussed here as long as nobody is actually implementing it and have proposed a review.
In general when discussion on blueprint starts to talk about such detail, I just leave it (like [Association blueprint](https://discuss.tryton.org/t/association-blueprint/1282)). The blueprint is about discussing the general idea.
