MRS (Multi Resource Scheduling) - Running /MRSS/HCM_RPTWFMIF from HR box


We have HR on a different box than MRS. We installed MRS 610 SP06 on the HR box. The MRS implementation documentation says "...customizing settings for MRS do not need to be done in the HR system, since only the HR communication part of the MRS will be used" so we didn't do any customizing (other than the RFC pointing to our box with MRS) to include not bringing in the standard SAP delivered customizing. When we ran the Transfer Report (/MRSS/HCM_RPTWFMIF) in the HR box it dumped (runtime error DYN_CALL_METH_CLASS_NOT_FOUND, exception CX_SY_DYN_CALL_ILLEGAL_CLASS). We did a little poking around in the code and it appeared that the Transfer Report was looking to see whether the use of HR or BP was set. We configured the basic settings to indicate HR and, when we ran the Transfer Report again, it proceeded to another dump (CALL_FUNCTION_NOT_FOUND, function module /SAPAP0/LRP_RESOURCE_CREATE not found). This experience has caused us to wonder whether some basic configuration of MRS on the HR box is, in fact, required. Does anyone have any experience running /MRSS/HCM_RPTWFMIF on an HR box seperate from MRS and what you might have had to do to get it functioning (in addition to defining the RFC)?
