Since the platform 27 update the possibility to update product item numbers has been depreciated. Product numbers can still be updated however. As advised by Microsoft we want to keep our product numbers alligned with the item number of a product over all our entities. We have cases where we need to update the product number of a product. For example when a new product is added, a transaction is made and we find out the initital product and item number where entered incorrectly. As soon as there has been a transaction, we are no longer able to correct it. This is now no longer possible without creating discrepancy between the product number and the item number or by creating a totally new product in all entities.
