In this video we will look at the function – ApplyMap() along with Mapping Load in QlikView. This function works similar to VLookup() in Excel. There are few things to remember before you start using ApplyMap() function.
- Use this function when you wanted to extract only one field from a lookup table
- First column should be lookup value or preferably unique id and second column is the output column you wanted to fetch
- Mapping table will only exist in the load statement
I am going to demonstrate a practical example on how to use both ApplyMap() and Mapping Load together to add additional field. I hope this helps! I recommend you to read Steve Dark’s post on ApplyMap() which covers in more detail. Please note there is a typo error on Unknown (not uknown).
