In MIRO screen, if clicked on 'TAX' tab error 'Entry of tax not allowed in

Question

Hi,
In MIRO screen, if clicked on 'TAX' tab  error 'Entry of tax not allowed in current account line' is displayed. Message number FF847. What may be the reason for this error message?
Entry of tax not allowed in current account line
Message no. FF847
Diagnosis
If you enter a tax amount in the current account line, the system does not allocate the amount to one tax code, but instead to all tax codes that exist in the document. In this case, the amount needs to be split up using the rule-of-three procedure. The sum of the computed taxes of all tax codes is used as the comparison basis. If each of the computed tax amounts of all tax codes equals zero, the system uses the sum of the tax base values as the comparison basis.
System Response
If the respective comparison basis equals zero, the system issues an error message.
Procedure
Go to the tax screen or tax tab page and enter the appropriate tax amounts for each tax code.

Hi,
Please check SAP Note- 1551857  for the same.
Other terms
FF707, FF716, FF796, FF847, FB70, SAPLTAX1
Reason and Prerequisites
There is a program error.
Solution
Implement the program corrections.
When you choose "Cancel" on the tax screen during posting or simulation, the system returns to FB60 or MIRO again.
The message FF 847 on the "Basic data" tab page is suppressed for company codes with jurisdiction codes if no expense items exist.
Hope this will resolve your query.
