[Anonymous]

Hi  am doing left join in my script but while loading am getting error like problem in prefix ,what could be the reason?

Could be the reason for different combination. If possible, will you able to provide sample code

Hi,

If you encounter 'illegal combination of prefixes' make sure you are not using noconcatenate function while joining or mapping.

Or if you use crosstable with leftjoin refer here illegal join on a crosstable - how do I makeit ... | Qlik Community
