MFG routings and standard hours for accounting vs demonstrated for scheduling

Hi,

This may be a cross-functional question.  We are on JDE Enterprise One 9.1 using process manufacturing.  We're running into a situation where routings are updated by accounting with "standard" run speeds that may or may not reflect "reality" for the shop floor scheduling process.  The schedulers are now requesting some type of change or alternate process to reflect true run rates for both scheduling and capacity.  Accounting is tasked with establishing what the acceptable rates should b.  I would like to think there is a way to create a "costing" routing that would be different from the standard manufacturing (M)
