DB2 Incremental dataload script error

[#1]

Hello Qlik gurus,

I am trying to configure DB2 incremental data load and having some trouble setting it up. I am using the following script. When I supply the time stamp the script works fine but when I use #$(LastExecTime)# then it gives me following error. Please help

The following error occurred:

Unable to get column information for the fields that are used in the query: ERROR [42S22] [Qlik][ODBC DB2 Wire Protocol driver][UDB DB2 for Windows, UNIX, and Linux]## NOT COLUMN OF INSERTED/UPDATED TABLE, OR ANY TABLE IN A FROM CLAUSE.

Script:

[VENDOR]:

SELECT "VENDOR_ID",

  "NAME",

  "ADDRESS_1",

  "CONTACT",

  "CITY",

  "PROVINCE",

  "POSTAL_CODE",

  "BUSINESS_PHONE",

    "ROW_TIMESTAMP"

FROM "TMWIN"."VENDOR"

// WHERE row_timestamp < '2016-01-27 00:00:00.000000'

WHERE ROW_TIMESTAMP > #$(LastExecTime)#;

Best regards,
