To be able to plan for cost elements, you first need to define <DS.GLOS.planning_layout>planning layouts. In the planning layout, you specify the format of the planning screens.
In the standard SAP System, planning layouts are found only in client 000. To use them as models for user-defined planning layouts, they must be taken from client 000 and imported to your production client. Use the IMG General Controlling under the section Prepare Production Startup -> Transport System Settings -> Transport Planning Settings -> Import Standard Planning Layouts .
After installing a new release or update, you should repeat the import of standard planning layouts from client 000 in order to access the latest layouts.
Procedure for Creating Planning Layouts
For the transport of planning layouts, an individual function is available in Customizing under Controlling -> General Controlling -> Production Startup Preparation -> Transport System Settings -> Transport System Settings -> Transport Planning Layouts.
