I am unable to see the GST amount in the sales invoice. It is showing instead. How can I resolve this?

Here's a simplified step-by-step guide for resolving the issue where the GST amount is not showing correctly on your sales invoice: 
 Issue: The GST amount on the sales invoice appears as 0, but it should have a valid value. 
 Step 1: Check Tax Category for Your Products 
 Make sure that you have assigned a valid tax category to each of your products in your item master. 
 Step 2: Verify the Skip in GST Option 
 In the item master, check if the Skip in GST option is set to Y. This setting may prevent the GST from being calculated on the invoice, resulting in a 0 GST amount. 
 Step 3: Disable Skip in GST if the Product Isn't Used 
 If you have products that are not used in your current vouchers (invoices), you can disable the Skip in GST option for those products in the item master. 
 Step 4: If you do use a product that has the Skip in GST option enabled, you have two options: 
 a. Create a new product without the Skip in GST option enabled. 
 b. Remove the product from all your existing item masters, disable the Skip in GST option, and then enter your vouchers again. This step might be necessary to ensure the correct GST calculation.
