Has anyone used this API before? I am trying to use it to get a plannable quantity from a specific date, but I can’t seem to get the right numbers to calculate. I am guessing I am misunderstanding one or more of the input variables.

   contract_           IN VARCHAR2,

   part_no_            IN VARCHAR2,

   configuration_id_   IN VARCHAR2,

   include_standard_   IN VARCHAR2,

   include_project_    IN VARCHAR2,

   project_id_         IN VARCHAR2,

   activity_seq_       IN NUMBER,

   dist_calendar_id_   IN VARCHAR2,

   starting_balance_   IN NUMBER,

   available_balance_  IN NUMBER,

   picking_leadtime_   IN NUMBER,

   planned_due_date_   IN DATE,

   stop_analysis_date_ IN DATE,

   site_date_          IN DATE,

   source_             IN VARCHAR2,
