ATP API for ATO Models

Hi,

We are trying to call the ATP API through a custom program. we are on oracle 11.5.10 with ASCP and using mrp_atp_pub.call_atp for making ATP calls. Does anyone have a sample script for ATP API specifically for ATO model scenarios. We are facing some trouble with the results returned by the API as compared to the inquiry made from the sales order form > availability > ATP details. The child items are not being considered when making the ATP call through an API, hence the SSD is incorrect. We do not have the star item created yet.

I tried comparing the data being written into the table mrp_atp_schedule_temp when the ATP call is made from the front end and from the API. The noticeable difference is w.r.t two fields - componet sequence id and the component code. As per the ATP guide, these two should refer to the child item chosen under the model in the sales order. However, the dataset pertaining to the ATP call made from the sales order form has different data for these fields. Am I missing something or any other data has to be passed?
