Formula and Condition Editor 
Use
You can use this
function to define or change 
formulas and conditions
that you then use in the following functions:
● Planning and Simulation
Formulas and conditions can be part of other formulas and conditions if:
● They belong to the same formula or condition type
● The formula is not part of itself (recursive)
● The formula or condition is active
By using formulas or conditions in other formulas or conditions, you can use these in the warehouse as general parameters, for example to always plan with a weight > 3.
Prerequisites
In Customizing, you have activated Labor Management.
For more information, see the Implementation Guide (IMG) for EWM under Labor Management ® Activate Labor Management.
Features
In the formula or condition editor, you can create, change, copy, and delete formulas and conditions.
You define a formula or condition using:
● A four-digit number
● Description
● Formula or condition type details
The formula or condition type decides which fields you can use for the formula or condition, and whether the formula or condition is valid for preprocessing, planning, or calculating the engineered labor standards.
Conditions for the preprocessing item and formulas for planning goals also require an external process step. This identifies the formula or condition that the planning or preprocessing uses for a particular step.
Formulas and conditions are connected to the transport system. They are transported as Customizing transports. The transport is optional for planning goals; for all other formulas and conditions, it is client-specific. If you have set the indicator Include in Transport Request for a planning goal, you can no longer delete it.
You can set the active indicator in the formula or condition. The system only considers active formulas or conditions in preprocessing, planning, or engineered labor standards.
When saving the formula or condition, the system checks the correctness of its syntax. If the formula or condition is not correct, the system automatically sets the indicator to inactive, and issues an error message.
You can also specify units of measure in the header of the formula or condition. By default, the system uses the units that you have defined for the warehouse number in Customizing for EWM. You can also use a different unit of measure here.
Activities
You define formulas and conditions on the SAP Easy Accessscreen, by choosing Extended Warehouse Management ® Settings ® Labor Management ® Condition Editor or Formula Editor.

Example
Example of a Planning Goal
● Formula 0001: total cost
● Ext. step: PICK
● Formula type: F Planning goal
● Weight unit: KG
● Unit of length: M
● Volume unit: M3
● Unit of time: MIN
Formula: (Planned duration of a workload record * fixed costs per minute * 100) / performance level
The system uses this planning goal to calculate the total cost for external step PICK.
This formula consists of the:
● Planned duration of workload record, which the system receives from the workload
● Fixed costs per minute, which are determined using a calculated measurement service
● Performance level that is specified in the processor
