in Ko88 getting error "settlement amount has an incorrect +/- "sign in sap

Hi Team,

I am trying to perform a negative capitalisation but SAP is not allowing

The process to follow is thus

I tick the box that allows me to post a negative value - I do this for tax and for Accounting values.

Then I add the negative amount in the settlement rule for the project

Next I run a settlement in KO88 - this is when I get the settlement error message below

please find attached screen shot for your reference.

kindly help.

Regards,
