Sort orders are stored at the Workspace level. They should be applied to the data category which is first defined in the Schema and View Editor module. The sort order should be defined for the Word list view (Section 2.2.2.1) (the sort order will define the placement of words in the word list in the Lexicon Editor). In the Schema and View editor, go to the Schema element tab, and in the tree in the left frame, select the data category to which you want to apply a sort order. Once the data category is selected, in the bottom part of the right frame select a sort order. Save through File> Save.
