Where do you maintain the data to determine the duration of an operation for production?

In SAP S/4HANA, the duration of an operation in production (e.g., for scheduling production orders) is determined by data maintained in:

Work center(A): The work center (transaction CR01/CR02, Capacity tab) contains capacity data and formulas (e.g., Setup Formula, Processing Formula) that calculate operation times based on machine or labor availability. The "Standard Value Key" (Basic Data tab) defines which time elements (e.g., setup, processing) are relevant, influencing duration.

Routing(C): The routing (transaction CA01/CA02) specifies operation details, including standard values (e.g., setup time, machine time) entered for each operation. These values, combined with work center formulas, determine the exact duration of the operation during scheduling (e.g., lead time scheduling in CO01).

Material master(B) provides in-house production time (MRP 2 view), but this is a high-level estimate for the entire material, not operation-specific.Production version(D) links BOMs and routings but does not directly store operation duration data—it references the routing. This is per SAP’s production planning master data structure.
