Key Figure Planning Levels for Supply Planning

Hi All,

I tried to take a unconstrained supply plan after modifying planning levels for certain key figures which were input/output to supply planning e.g. Production.

I am getting the below error now. Thus wanted to understand the flexibility provided by IBP in modifying the key figures related with supply planning. I wanted to aggregate the key figure data to a different planning level and thus modified the planning level. Is the below error occuring because of that? Any inputs on this will be highly helpful
