Repro Steps:
Navigate Accounts receivable -> updates -> update order lines and quotation lines.
Update order lines
Update quote lines
Navigate accounts receivable -> all sales order -> create new with item and check the dates.
Change requested ship date and save it
Choose update ship and receipt dates yes and recalculate delivery dates
Lines date remains same. (which is correct behaviour)
Navigate sales and marketing -> All sales quote-> create new and check the dates
Delivery date control is ATP
Change requested ship date and save it
Update quote lines. We have only update request ship and receipt lines. (Different with sales order. We cannot recalculate delivery dates)
After updating sales line is getting change. ATP is not considering on sales quote.

Actual Result:

Sales order delivery date updates and sales quote update are different. In sales order it is working as expected. But in sales quote while update delivery dates it is not considering ATP. We cannot recalculate delivery dates on sales quote.


Expected Result:
Sales order and sales quote delivery date updates should not be different. In sales order it is working as expected. But in sales quote while update delivery dates it is not considering ATP. We cannot recalculate delivery dates on sales quote.
