Incremental Load: And Field not found error

[helen_pip]

Hello

I am in the process of trying to write an incremental Load statement, but have 2 problems so far

The Errors

1)  I get an error message stating:

Field not found - <>>

SECOND_LOADS:

2) The rest of the script LOADS o.k, but it adds the totals together, but as I am new to Qlikview I do not know that if I sort out problem 1, problem 2 will cease to exist

The 2 QVDS

INITIAL_LOAD.qvd is loading in data between 01/05/2012 and 30/09/2012 (Results = 87427 rows)

SECOND_LOAD.qvd is loading in data from between 01/10/2012 and 30/09/2013 (Results = 218386 rows)

Both QVD's contain the same field names

The Aim

The aim is to concatenate SEOND_LOAD onto the end of INITIAL LOAD so I end up with 305813 rows (87427+218386)

Can anyone kindly help?

Concatenate

[#2]

Hello,

The last command could be unnecessary because qlikview will automatically concatenate 2 tables which have same columns unless if you don't use Noconcatenate command.

So maybe you should try without the last Concatenation part.

Try without this:

Concatenate
LOAD* FROM

Q:\DEVELOPMENT\HP\QVD\INITIAL_lOAD.qvd
(qvd);

Best.
