How to link a planning function to the input ready query
I am quite new to Integrated planning. I have created a planning function (repost) in IP modeler. I have created a workbook which enabled input ready query(which is working fine). Now my issue is how to link the created planning function(repost) in the workbook.
1) Can we do this through BEx. If yes, kindly let me know the 'how' process
2)I am to write a code that validates the key figures. Please let me know if once code is writted, can I call this code(formula) from the BEx.
