Configured ATO Item And Scheduling - Not Getting Right Results (Doc ID 2022635.1)

Last updated on MARCH 08, 2017

Applies to:

Oracle Global Order Promising - Version 12.1.3 and later
Information in this document applies to any platform.

Symptoms

12.1.3.9.1 in Production and Test
ATP based on planning data

PROBLEM
-------------
ATO Model with Flow line at Model level with capacity 10 / day
- model as Phantom Mandatory Component from feeder flow line that has capacity of 3/day - so this is the constraining resource.

When they enter the ATO model and configure and schedule, they get back the expected date - e.g. 15-APR
-- the order qty 3 was entered so that it used up capacity for date 15-APR on feeder Flow line
SO -- any new order entered for same qty 3 - would get ATP date of 16-APR and is fine.

BUT -- if they unschedule and reschedule the original sales order line, they also get 16-APR date and if you do this twice, then the date moves out another day to 17-APR


EXPECTED BEHAVIOR
----------------------------
Resources availability will be freed up and re-used if order is unscheduled and reschedule
OR IF order is unscheduled and new order is entered, then that resource availability will be available.

BUSINESS IMPACT
----------------------
getting wrong schedule dates and this can only be rectified by running collections and ASCP ATP plan.
