Hi, i assume that i know.
i configure two places in customizing:
SAP Multiresource Scheduling - Sources of Demand - PM/CS Orders - Control Automatic Assignment Creation (ERP)
and
SAP Multiresource Scheduling - Sources of Demand - PM/CS Orders - Define Search Strategy for Automatic Assignment Creation (ERP)
as it says in help http://help.sap.com/saphelp_mrs900_erp/helpdata/en/88/93b698d5b84aba93ec602bb2429255/content.htm?frameset=/en/6d/21cad912e249479e35188d2d608d1b/frameset.htm
but in "Define strategy" i can not set nothing but "Conc. Slot" (Flag to search availabiltiy for Concrete Assignment).
when i set anything else (deactivate Conc. Slot), i recieve error - "Partner is not available".
