Goal

The customization/Custom code starts only after the data is populated in MRP_ATP_DETAILS_TEMP table.
We are trying to populate the MRP_ATP_DETAILS_TEMP table using the standard ATP API.

The issue I'm trying to address here is and I need Your help on is ,

The mismatch in data in the MRP_ATP_DETAILS_TEMP table between the following 2 options.

Option 1 :
Responsibility : Order Management Super User
Navigation : Scheduling > ATP Inquiry

Demand Class - A
Org - US2
Item - BB
Qty - 999999
Request Date - 24-JUN-2016

Hit 'ATP Details' button.
Once You are in the ATP Details window,
Help > Diagnostics > Examine and pick the SESSION_ID

Now try to query the MRP_ATP_DETAILS_TEMP table with the SESSION_ID.
It will return few rows. Check the CUMULATIVE_QUANTITY for each PERIOD_START_DATE.

Option 2 :
Run a Program calling the ATP API and pass the same set of parameters,
Demand Class - A
Org - US2
Item - BB
Qty - 999999
Request Date - 24-JUN-2016

Now pick the SESSION_ID from the log file of the program and query the MRP_ATP_DETAILS_TEMP table.
The CUMULATIVE_QUANTITY for PERIOD_START_DATE is different in this case.

The only difference is , We are passing 1000 Items into the API to get the output.This is done to handle the performance.

We are using details from the MRP_ATP_DETAILS_TEMP to build custom report on large numbers of items and need the correct information as seen when using the ATP Inquiry form.
