95 Values Returned : None
96 Description : Acts as a cover procedure to change_ses_date.
97 Inserts or updates a row into FND_SESSIONS for the
98 current session. If the p_effective_date parameter
99 is provided the row will be modified with
100 a truncated version of that date. If p_effective_date
101 is set to null then trunc(sysdate) will be used.
102 If p_do_commit is set to true this procedure will
103 issue a commit when required. If p_do_commit is set
104 to false this procedure will not issue a commit.
105 It is then the calling code's responsibility to issue
106 a commit as soon as possible. Otherwise there is
107 a risk of the internal package global variables
108 getting out of synchronisation with the
109 FND_SESSIONS column values.
