ADempeire 361 maintenance asset meter error - need simple step to modify

Hi all
I was trying to set maintenance on ADempiere 361 with FAM and maintenance
set by https://groups.google.com/forum/?fromgroups#!topic/idempiere/j4nBYQ-2f4c
(http://erpinfosystems.blogspot.com/2012/12/adempiere-361-final-with-maintenance.html
and :
1) asset_meter its error by datetrx on mp_assetmeter table which could be set as
DEFAULT CURRENT_TIMESTAMP
2) a_asset_disposed -  column isapproved should be set as default 'Y'
then it should be save Asset meter, disposed and meter log as addition
for assets regards preventive and corective maintenance.

If its posible, should be fine that this simple correction post on
official code repository, or if it's not posible, future users can simple change
this from database.

 table 1: asset_meter its error by datetrx on mp_assetmeter table which could be set as
DEFAULT CURRENT_TIMESTAMP

table 2:a_asset_disposed -  column isapproved should be set as default 'Y'
need restart application, (re login) and all should wrk fine.
log in as 
super user (Administrator)  and Application Dictionary-Window tab & field
and on WORK ORDER  found  field : Document Status when un set Read only could be writable. After that all maintenance module working perfect.
