Fixed Query update DATETIME issue

Question

I'm trying to convert a VARCHAR value to a DATETIME value in a table in a SQL database with the following Fixed Query Details:
update SAPQNJDB.MPM_AFKOL
set GSUZS =  CONVERT(Datetime,'2012-03-28 11:10:00.000')
where AUFNR = '000001000648'
But I receive the error as below:
SQL error has occurred on query The SQL statement "update SAPQNJDB.MPM_AFKOL
set GSUZS =  CONVERT(Datetime,'2012-03-28 11:10:00.000')
where AUFNR = '000001000648'" contains the syntax error[s]: - 2:14 - Intermediate-SQL syntax error: CONVERT or TRANSLATE function not allowed
- 2:30 - SQL syntax error: the token "," was not expected here
- 2:30 - expecting "using", found ','
SQL Version is 2008
SAP MII Version 15.0 sp 0 patch 0
Type: Querytemplate
Datasource Modes: Command
A normal select query on the same tables just works fine.

Issue is solved.
Changing the datasource from DataSource(SQL) to IDBC(SQL) did the trick
