MIRO - Duplicate Invoice check for Fiscal year

Hi Guys,

I have a requirement, where I need to give the error/warning message ,if invoice in MIRO is posted with same Reference number ,same amount , same PO and same Company Code , but with other date in the same fiscal year .

Right now if date is in another fiscal year , then also it is providing the message .

e.g

Already posted Invoice :

Refrence : DEVTEST3

Amount : 2 000,00

PO : 2050664973

Company Code : 1226

Date   05.12.2015

If trying to post the invoice in next fiscal year , then it should not give the message .

Refrence : DEVTEST3

Amount : 2 000,00

PO : 2050664973

Company Code : 1226

Date   22.03.2016

Kindly let me know , how to achieve it.

Thanks,

Sachin Sharma
