As mentioned above,
a)The wage types need to be changed in V_512W_D proc cl 10 to a value 9.
b)I would suggest you do not change the standard PCR's or schemas. Standard practice is to copy/create a customer PCR or schema with a Zxxx name. For example XPP2 is copied as ZPP2 and changed as required. When a pcr is changed, the schema which calls is is customized, then all the sub-schemas above and the main one.
