Why is the Order Requisitions page changing the Order Rate after selecting vendor

AI generated answer (using internal Slack threads):

The "Order Rate" in the "Order Requisitions" page is typically derived from the related item record. If the Purchase Price field is left blank, NetSuite defaults to showing the most recent purchase price for that item. If you want to set a specific price, you should enter it in the Purchase Price field. Leaving it blank can lead to unexpected values being displayed. In the case of the rate and amount of an item changing when the address on a vendor record is edited, this is not a standard behavior in NetSuite. The rate and amount should not change unless someone manually changes the item line rate. If such a change is observed, it's recommended to review the line history to see if someone made the change intentionally. For situations where the vendor wants the item rate to be a percentage of the sales price, this can be achieved through scripting. You can create a script that goes through the lines, gets the item rate, calculates the percentage, and sets the custom item rate. To make this process more flexible and scalable, you can add a field on the vendor record to store the percentage markup. This way, if you need to change it later or have another vendor who wants to do this, you can just update/add the value in that field and use that logic in your script. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
