Hi,
You may have different formulas depending on whats your bottolneck resource in terms of Capacity & Scheduling.
Again, If you have Operation split / Operation Overlapping, your capacity requirement may remain same but your scheduling would surely change as the Processing time has been split.
You may take a look at [Operation Split, Operation Overlap|http://help.sap.com/erp2005_ehp_03/helpdata/EN/7e/d419b7455911d189400000e8323c4f/frameset.htm].
Also see [Work Center Formula|http://help.sap.com/erp2005_ehp_03/helpdata/EN/b1/c0392e439a11d189410000e829fbbd/frameset.htm].
Eg. A work center has 2 machines to process the job and it is possible to split the operation, the Capacity & Scheduling requirement would be as follows (assuming that both the machines are identical):
Capacity : Setup * 2 (2 - since the set-up has to be done twice (Setup * Operation splits)) + Processing Time ( Machine * Operation quantity / Base qty)
Scheduling : Set-up time + Processing Time / 2 (Machine * Operation quantity / Base qty / Operation splits)
Hence, the need to have different formulas.

Hi,
Please try to understand the difference bet. scheduling and capacity requirements formula.
the formula for scheduling calculate the lead time of an operation while the formula for capacity calculates the capacity requirements to be generated for carring out the operations.
Hope the difference is clear.
Thanks & Regards,
