Engineered Labor Standards
You use this function to define the times that are required to execute an activity in the warehouse. The system calculates engineered labor standards (ELS) when:
● Creating a document, when the system generates planned workload
● Confirming a document, when the system generates executed workload
The system saves the labor standards in the planned workload as planned duration, and in the executed workload as an adjusted planned duration.
The final data is only available when you have confirmed the document, as only then is the executing resource known and therefore also the:
● Speed of the resource
● Last position of the resource prior to executing the activity
● Travel distance allowed for the resource
The system uses this additional data for the travel distance calculation. It saves the results of the travel distance calculation in the planned and executed workload. You can include a formula or condition as parameters when defining the engineered labor standards.
● For the speed, the system uses the slowest resource (pessimistic approach).
● Instead of using the exact position of the resource, the system uses the default distance. The default distance is the distance traveled to reach the first item of a storage type.
● The route network, which contains all defined routes without resource type restrictions.
● Operational planning of the planned workload
● Evaluating employees by comparing the measured time with the planned time stored in the workload
You can influence the results of the engineered labor standards in BAdI /SCWM/EX_ELS, in enhancement spot /SCWM/ES_ELS, by using the following two methods:
● START_DEFAULT
You can use this method to deactivate the implementation for engineered labor standards delivered in the standard SAP system. This may be appropriate for performance reasons if the calculation is done customer-specifically.
● CHANGE_ELS_RESULT
You can use this method to change or overwrite the result (planned time, unit of time) of the ELS calculation.
For more information about this BAdI, see the Implementation Guide (IMG) for Extended Warehouse Management (EWM) under Business Add-Ins (BAdIs) for Extended Warehouse Management → Labor Management → Engineered Labor Standards → BAdI: Changing Standard Time Determination.
● To save the ELS result in the planned and executed workload, you have activated Labor Management.
● You can use the result of the travel distance calculation for the engineered labor standards.
● You can use the planned time calculated via the engineered labor standards in operational planning.
● You can evaluate employees by comparing the adjusted planned time with the actual execution duration.
● You have activated Labor Management.
● You have defined formulas in the formula editor and conditions in the condition editor.
● You have defined engineered labor standards in Customizing for EWM, by choosing Labor Management → Determine Engineered Labor Standards.
