Documentation on reorder: Auto Creation of Material Request

Will be happy to help if you have more questions after referring to these links.

I have set the product A reorder level to 15, reorder quantity to 20 and the entry stock only 10
after that i have create an sales order to this product A which sell 15 unit.

I have not seen material request is created automatically. but when i click pick list from the sales order, it tells the product A is not enough

My question is what do i need to do to make it automatically create a material request ?

Does it suppose to create a material request for me right now but it didnt ?

The scheduler checks the Inventory Level once at midnight by default.
If it finds that the Quantity is below the Reorder Level, it will create a Material Request equal to Reorder Quantity.

So it will only create material request once a day when checking at the midnight ?

it is possbile to make it create the material request whenever out of stock ?

Yes the system will check for the Quantity at midnight and create a Material Request if required.
The event of checking for Inventory levels is done at certain interval which is set as midnight currently.
