RCM transactions

Reverse charge mechanism (RCM) transactions are posted for a vendor that is marked as a goods transport agency (GTA). Additionally, the transactions are marked to indicate that the reverse charge percentage was updated to 100 percent in the tax document. However, the value of the Is reverse charge applicable field isn't updated to Yes on the GSTR 2 report.

To fix this issue, when you create a new posting type for a tax payable in a tax configuration, select Tax in the Tax accounting provider field and Tax payable in the Tax Posting Type field.

Tax accounting provider and Tax posting type fields in the Posting type dialog box.

For more information, see RCM transaction for GTA vendor does not show as "Y" in RCM column in GSTR2 report.
