Hi raj
we have to use formulas in the workcentre to calculate following data in costing,scheduling and capacity planning:
Costs for operations
Execution times for production orders
Internal processing times for networks and maintenance orders
Capacity requirements.
To calulate cost of the operations we have to define formulas in costing Tab.
1.based on this formuals, time required to complete the each operation in the routing is calculated , using standard values in routing
2.system uses, this time and activity type which u have already assigned in casting Tab , to calculate cost.
3.before that u have assigned activity type to cost center, where u have defined the value for operation like 100 Rs/Hour.
SCHEDULING FORMULA:
let say example,
suppose one opretaion has following standard values,
Machine time : 6 Mins
operation qty : 10 Nos
base qty of the operation : 1 nos
for scheudling u have to define the formula in the workcenter scheduling tab.
Formula= machine time * operation qty/ base qty of operation.
= 6*10/1 = 60 Mins.
so cost of the operation is 100 Rs.
what i have given is for example, like wise u can use standard formula or u can create your own formaula.
To create work center formula GOTO SPRO -> OP17,OP21
reward the points if it helps to clear ur doubt

eg : To calculate capacities in work centre
1) setup formula : SAP005 (setup x operation splits)
2) Processing formula : SAP006 ( Machine x operation quantity/ base quantity)
3) teardown formula : SAP007 (labor x operation quantity/ Base quantity)
Formulas for scheduling in Work centre
1) Setup formula : SAP001( Setup)
2) Processing formula : SAP002 (machine x operation quantity/base quantity/operation splits)
3) Teardown formula : SAP003 (labour x operation quantity/base quantity/operation splits)
and so on these were just examples of predefined formulas in SAP. It takes the values from the data that you have maintained in the routing.
