The problem occurs when a field filter is not specified in a LOAD statement that gets data from a .parquet file.
This simple script provides an example where the issue can occur:
TEST:
LOAD *
inline ['docCode','docName','docStatus'
'A1', 'Description A1','S',
'A2', 'Description A2','S',
'A3', 'Description A3','N',
'A4', 'Description A4','N',
'A5', 'Description A5','S',
];
Store TEST into [lib://test (domain_administrator)/test.qvd] (qvd);
TEST:
LOAD
docCode,docName,docStatus
FROM [lib://test (domain_administrator)/test.qvd] (qvd)
WHERE docStatus = 'N';
You get the error message if you remove ,docStatus from the latest LOAD.
The problem does not occur if you store the content in a QVD file.
Resolution
The problem is fixed in Qlik Sense May 2024.
A possible workaround is to specify the docStatus field in the LOAD statement and then drop the field after the filtering, like in this example:
LOAD *
inline ['docCode','docName','docStatus'
'A1', 'Description A1','S',
'A2', 'Description A2','S',
'A3', 'Description A3','N',
'A4', 'Description A4','N',
'A5', 'Description A5','S',
];
Store TEST into [lib://DataFiles/Ptest.parquet] (parquet);
Drop Table TEST;
TEST:
LOAD
docCode,docName, docStatus
FROM [lib://DataFiles/Ptest.parquet] (parquet)
WHERE docStatus = 'N';
Drop Field docStatus;
