I am unable to view the TCS collection code in BUSY. How can I find and apply this?
You can only view the TCS collection code in the sales voucher in which you have applied the TCS.
Step 1: Click on Transactions
Step 2: Then Sales
Step 3: Then Modify
Step 4: Select the voucher in which applied the tcs and when you save the voucher then TCS window will get open and check it Collection code R for sale of goods and E for Scrap.
