## Description: function Update_Approval_DB
## This function updates the approval database with the

## Author: T.Baron
## PARAMETERS: categformatDAM: variable used to compute the category
## of the document from its reference

"""
This function updates the approval database when a document has
just been approved or rejected. It uses the [categformatDAM]
parameter to compute the category of the document. Must be called
after the Get_Report_Number function.
Parameters:
* categformatDAM: It contains the regular expression which
allows the retrieval of the category from the
reference number.
Eg: if [categformatDAM]="TEST-<CATEG>-.*" and
the reference is "TEST-CATEG1-2001-001" then
the category will be recognized as "CATEG1".
