CHANGING PLANNING LEVELS OF A KEY FIGURE

Hi,

I created a planning level at the MTHPRODLOC level and copied that planning level to create PERPRODLOC (Month weight distribution)

I assigned MTHPRODLOC to a key figure and loaded values to it. I changed the baseplanning level of the key figure to PERPRODLOC. After which, my data was lost. I'm trying to switch back to the original planning level. Could you advise me on how to retrieve that data?

Thank you!
