Here is the setting of my routes which is activated in Product A
Product A:

1. MTO

2. Warehouse A: Resupply from Warehouse B

3. Buy

Current Stock:
Warehouse A/Stock = 39

Warehouse B/Stock = 10

I noticed that if I open a sale order where the quantities of product A = 49 it display this error:
There is no matching vendor price to generate the purchase order for product [026-0105] ไม้เส้น 026 (no vendor defined, minimum quantity not reached, dates not valid, ...). Go on the product form and complete the list of vendors.

And it would create RFQ automatically if I have entered vendor price, even though when we combine the stock it would have been enough.

However, if current stock of Product A is the following:

Warehouse A/Stock = 10

Warehouse B/Stock = 50

When warehouse B has enough stock there would be no error.

Is there a way to configure the route such that it could split the picking into two locations (like pick from warehouse B 10 units -> move to warehouse A and pick another 39 units)

Thanks in advance
