For point 2 is a straight yes
For point 1, I would recommend you to get a delegation from offer marketing to make sure both side of the data are in line
For Indent Item the purchase and sales have to make sure the offer is sync so we give good information to customer and to the market.
Otherwise the following may happen
(1) generate excess stock in country
Eg: Y102A, Rounding Value = 10 and Delivery Unit = 1, customer order 3 will make Thailand carry 7 pcs of Excess stock
(2) down-graded Schneider Offer to customer
Eg: Y102A, Rounding Value = 1 and Delivery Unit = 10, customer wanted to order 3, but Schneider say no to the order as the offer does not allow the order of 3 to go through. At the end customer turns to buy, for example, Legrand product
Both of the situations generate no advantage to Schneider. So what I would recommend is to tell the offer marketing that you will be updating as-is what it is in PRODAT every week
