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?
