Text for VAT line item in MIRO

Hello,

While posting a MIRO, if we select 'calculate tax', the line item for input tax is generated directly in the accounting document. There's no way to enter text (SGTXT) for this line item since it's automatically generated and appears nowhere while doing MIRO/MIR7.

Need your help to understand if there's a way to add text, for line item belonging to tax, while parking/posting the invoice in MIRO/MIR7 or is this a limitation of SAP?

Thanks & Regards,

Suresh
