I would like to bring your attention to the efforts required to address this requirement. The steps in sequence and the efforts are:
a. Business logic: pending (Vsmt to look for replacement of KPMG K. Guin) to amend GL posting rule
b. Data flow changes: 2-3 days by KC to change data flow
c. ETL: ? days by Vsmt change the ETL according the changed data flow
As you can see, we need only 2 or 3 days to get this done but Vsmart needs to appoint an accounting firm to come up with the GL posting rule, and only upon the rule has been accepted by GSB, we can then carry out the work to change the data flow and then depend on your team to amend the ETL rules. This might takes months.
It is a lot of cost and effort to address a requirements that GSB does not need at this point in time.
Appreciate if you can have a word with your team to verify the information above and if you can have a word with K.Boonson, that will definitely help to ensure the project get signed off on time.
