To transport planning model objects to another system, you can use the BI transport connection and BEx transport requests (see Planning Business Data with BW Integrated Planning).
Variables and filters that you have created in Planning Modeler behave like the corresponding query elements. You have transport object ELEM.
Unlike BEx objects however, planning objects are written to the BEx transport request or requests, even if the standard transport system is activated.
This applies to the following object types from the planning area:
ALVL (aggregation level)
PLCR characteristic relationships
PLDS data slices
PLSE planning function
PLSQ planning sequence
PLST planning function type
More information: Transport-Relevant Object Types.
Follow the procedure outlined under Transporting BEx Objects.
