Why am I unable to push certain transactions that are labelled as failed?

You might not be able to push transactions to the GST portal due to the following reasons:

• The credit notes have values that are less than or equal to zero.
• The transactions in the Documents Issued tab, has special characters other than alphabets, numbers, / and -.
• The HSN has more than 8 characters.
• The amounts in the transaction round off to 3 decimals.
• Incorrect Shipping Bill Port Code and Shipping Bill Number.
• Incorrect GSTIN format.

You will have to update the transactions with the correct values or formats and push them again.
