Hi,
You can amend your old PP as per the new calculation provided above..
But curious to know why you cannot take SB tax on separate line? what nature of business your dealing with?
Coming to you point:
1. When there is no Swachh Bharat Cess
When there in no SB tax then don't maintain the value in VK11 or manually.
2. When SBC is required in separate line item.
For separate line you you need top configure new PP.
But why point to will come in your case when business don't want to take the credit of SB tax as mentioned by you earlier.
In case business is asking to for both option for SB tax then you need to make them understand this is not a good business practice.
Thanks
Sumeet
