Code for Excel import by choosing file in Axapta

This is a very useful code for importing excel into DAX table. Developer can add/modify their logics while importing excel into DAX table. This is a simple and compact code. Developers have to change this code as per their requirements.
Note: Here excel file will be 3 columns, 1. Vendor Code, 2. vendor Group and 3. vendor Currency. You can add or less fields in excel but same incorporation should be done in this job (bold area). While you incorporate this type of procedure then I recommend to all do this code into a class instead of job.
