SAP BW IP= Sales and Production Planning

Hi ,

If manual changes are made to sales planning through the input-ready Sales query, these changes are also visible in the Cross query. The Cross query is defined on aggregation level Cross ALVL which also contains the sales InfoCube.

The customer has implemented planning function Simulate, which specifies the relationship between the different key figures in the Sales, Production, and Profit and Loss InfoCubes. This function copies any changes to sales planning to the Production and Profit and Loss planning.

For this which type of Planning function i need to use? and Can any one explain the steps ?

Thanks in advance.
