"Computer says no". :) I'm inclined to believe SAP in this case, sorry. You might be missing something in calculations. There was the exact same question asked before and possibly more information can be found on Google and in the SAP notes.

Switch to ALV Grid output, if possible.

P.S. I'm not sure what are the magical numbers under the signature here but please be aware that sharing personal contact info in the questions is neither wise in general nor encouraged on SCN.

I tried Switch to ALV Grid, still facing the same issue, i already done the google, but i couldn't found the correct one, then only posted into SCN. Checked all the calculations by myself and one of my team met also. Please any one suggest, where i did the mistake. Please don't suggest do google and all.


Check for the SAP notes in case it's an already known bug (try ANST transaction for that). You can also try debugging to see where the message occurs exactly.

Otherwise at least post more details, like the exact steps and screenshots. Not sure what else can be said based on the limited information available...
