SAP GRC 10.0 on ECC

Hi Guys,

We are planning on implementing SAP GRC 10.0. Our Basis guy has suggested that we can use ECC (EHP 6) box for installing the add on(GRCFND_A) component for it. The reason for this is to avoid adding another system to the landscape and to reduce the cost of implementation

Are there any known issues using this approach?

Thanks in advance,

Silver
