15 -- Description:
16 -- This procedure controls the actual dml insert logic. The processing of
17 -- this procedure are as follows:
18 -- 1) Initialise the object_version_number to 1 if the object_version_number
19 -- is defined as an attribute for this entity.
20 -- 2) To set and unset the g_api_dml status as required (as we are about to
21 -- perform dml).
22 -- 3) To insert the row into the schema.
23 -- 4) To trap any constraint violations that may have occurred.
24 -- 5) To raise any other errors.
25 --
26 -- Pre Conditions:
27 -- This is an internal private procedure which must be called from the ins
28 -- procedure and must have all mandatory attributes set (except the
29 -- object_version_number which is initialised within this procedure).
30 --
31 -- In Parameters:
32 -- A Pl/Sql record structre.
33 --
34 -- Post Success:
35 -- The specified row will be inserted into the schema.
36 --
37 -- Post Failure:
38 -- On the insert dml failure it is important to note that we always reset the
39 -- g_api_dml status to false.
40 -- If a check, unique or parent integrity constraint violation is raised the
41 -- constraint_error procedure will be called.
42 -- If any other error is reported, the error will be raised after the
43 -- g_api_dml status is reset.
44 --
45 -- Developer Implementation Notes:
46 -- None.

109 -- Description:
110 -- This private procedure contains any processing which is required before
111 -- the insert dml. Presently, if the entity has a corresponding primary
112 -- key which is maintained by an associating sequence, the primary key for
113 -- the entity will be populated with the next sequence value in
114 -- preparation for the insert dml.
115 --
116 -- Pre Conditions:
117 -- This is an internal procedure which is called from the ins procedure.

120 -- A Pl/Sql record structre.

122 -- Post Success:
123 -- Processing continues.
124 --
125 -- Post Failure:
126 -- If an error has occurred, an error message and exception will be raised

128 --
129 -- Developer Implementation Notes:
130 -- Any pre-processing required before the insert dml is issued should be
131 -- coded within this procedure. As stated above, a good example is the
132 -- generation of a primary key number via a corresponding sequence.
133 -- It is important to note that any 3rd party maintenance should be reviewed
