  switch and options are just like codes
  say parts/lines and fields
  they work on the conditions like if the voucher is a sales voucher then use optionsA (Those options will have the same codes but with a different setup/data etc)
  Same way switch are like the switches we use in our homes for electricity like a switch for fan, tube light etc.
  Concept was to give an idea about what switches and options are. there can’t be special projects on switch/options. because they are using in the projects as a part of projects they can’t become an independent project on its own.

In our company Tally uses full fledged with inventory & taxation module. I have learned a lot in our organization. I do share one interesting event happened while doing service. Tally had launched one scheme for students ‘Earn while Learn’. I have participated & done more that 10 activations while learning Tally on that scheme. Its given inspiration to my career in Tally. After successful completion of my 8 years service, I have decided to move Pune. When I have decided to move Pune, I have two options shall I go with again service or business. I have decided to go with the business. But again so many questions in front of me which business, etc?. With the help of my ‘Guru’s, My Family Members, Friends I have chosen my career in Tally World & I have become Tally Partner recently. I am a knowledgeable person in the field of Tally.ERP9 but again If you want to survive in the field of Tally, you should know TDL.
