HI,
Whenever you will go for any custom PCR and want to place it in the schema then that schema should be copied to custom. Since in the future if you will try to refer the standard schema which will give you wrong information or some one others.
Regarding your question on my last reply that you have to pass the custom wage type not /3E7, /3E8 and /3E9...
