One of the issues using reservation functionality is the ability to calculate flexible whether a quantity is possible or not.
In this scenario, if I enter 13, I can see with assigned quantity that it actually assigned 13, but I could also see here on the warning that it’s not possible because some of it is reserved.
So, looking at the graphical profile for this cell total line I just entered, seems fine. So, we have enough items .
The problem is it’s already reserved, meaning if I go into the reservation entry, the engine, and try to auto-reserve, I can see it’s not possible.
So, the issue of changing this reservation is quite complex.
What I need to do is to open my item list.
So, I’m trying to change this with the standard functionality.
On my item list, I would look for the preservation entries. And here.
So, here I get a list of all the reservation entries for this specific item reserved up to many different sales orders.
And here I can select some of them.
I need to look at the dates and I need to cancel the reservation in here to be able to reserve to my new sales order line.
But I will also have to re-reserve all the sales orders that I just canceled.
And this is quite a complex exercise.
So, with assigned quantity, it’s possible to calculate if it’s possible or not, and not use the reservation entries.
