120 -- Description:
121 -- The Lck process has two main functions to perform. Firstly, the row to be
122 -- updated or deleted must be locked. The locking of the row will only be
123 -- successful if the row is not currently locked by another user.
124 -- Secondly, during the locking of the row, the row is selected into
125 -- the g_old_rec data structure which enables the current row values from the
126 -- server to be available to the api.
127 --
128 -- Prerequisites:
129 -- When attempting to call the lock the object version number (if defined)
130 -- is mandatory.
131 --
132 -- In Parameters:
133 -- The arguments to the Lck process are the primary key(s) which uniquely
134 -- identify the row and the object version number of row.
135 --
136 -- Post Success:
137 -- On successful completion of the Lck process the row to be updated or
138 -- deleted will be locked and selected into the global data structure
139 -- g_old_rec.
140 --
141 -- Post Failure:
142 -- The Lck process can fail for three reasons:
143 -- 1) When attempting to lock the row the row could already be locked by
144 -- another user. This will raise the HR_Api.Object_Locked exception.
145 -- 2) The row which is required to be locked doesn't exist in the HR Schema.
146 -- This error is trapped and reported using the message name
147 -- 'HR_7220_INVALID_PRIMARY_KEY'.
148 -- 3) The row although existing in the HR Schema has a different object
149 -- version number than the object version number specified.
150 -- This error is trapped and reported using the message name
151 -- 'HR_7155_OBJECT_INVALID'.
152 --
153 -- Developer Implementation Notes:
154 -- For each primary key and the object version number arguments add a
155 -- call to hr_api.mandatory_arg_error procedure to ensure that these
156 -- argument values are not null.
