Unexpected behavior of available to reserve API after creating Hard Reservation

Summary:

Creating hard reservation in oracle scm gives 0 as Available to Reserve Quantity (ATR ) using the rest api for fetching the available to reserve qty

API URL:

/fscmRestApi/resources/11.13.18.05/availableQuantityDetails

This is the sample payload that i pass

{

"OrganizationCode" : "",

"ItemNumber" : "",

"Subinventory" : "",

"Locator" : "",

"Lot" : ""

}

What happens is when i update or create the reservation then available to reserve qty is reserved and i can see that in Oracle Fusion UI but its showing as 0 ATR qty if fetched using the above API.

But as soon as i pick release the line, then again i am able to fetch the ATR qty using the same API.
