What EHP Is My HR On?

Hi Guys,

I've read through the different discussion and SCN blogs but I'm still confused with the EHP version that my client's SAP HR is on. Below is the info that I pulled down from SPAM. In it I know that system wise and for the Logistic component they are on EHP6. But yet when I see SAP_HR it shows 604 which means HR is on EHP4? But EA-HR shows 606 which means EHP6?

So in the end am I correct to say that for HR the client is on EHP4?

Would very much appreciate your kind help and advice guys.

Thanks and regards,

Danny
