Rescheduling of sale order

[Former Member]

We have following scenario in scheduling of sale order

1. When sale order is created for the first time , it runs the avl check & the Goods Issue date is determined based on the cAvl control paremeters set in OVZ9 . At that point of time , we don't have any stock & planned receipts .Hence order gets scheduled based on TRLT set in material master

2. When a planned receipt is created later in system , its date is generally scheduled beyond TRLT of the material .e.g. TRLT of material is 7 days & the planned receipt may be expected to arrive adter 21 days

3. In such cases , we have to change the Goods Issue date in sale order by running the avl check again .

Problem : When we run the avl check in sale order again , it takes the TRLT into account & doesn't change the date as per planned receipt date , which is a more confirmed element than TRLT

How we can achieve this

Normally the TRLT is longer than any other supply element; this is the basic idea behind it.

In your example, I don't think hat regular ATP will be enough. You may ned to employ a user exit or use APO/GATP engine.

Alternatively, use the normal TRLT logic, and make it longer; anyway, how does it look for the customer when you confirm delivery in a week based on TRLT, and a couple of days later you call him to reschedule to 21 days!!!

Isn't it better to schedule for a month in the first place (TRLT), and then call the customer to anounce that you managed to shorten it to 21 days?
