Which parameters in FME will enable the display and sorting capability based on the "alias" field in a shapefile?

Thanks David. I have been able to rename the attributes using the AttributeRenamer transformer in FME but ideally I would like to import the attributes directly from an ESRI shapefile using the alias field (screen shot attached)

Alias is also available using shapes. (I often do this, when I'm too lazy to reprocess the data...). Mostly when creating map-books with queries and map-queries for output.

But you can't access it trough a shape reader because afaik it is not information in the shape file but in the mxd.

So as per @cartoscro hint, you'll need to save the data into a geodatabase wich would make it accessible trough the gdb reader.
