Key Figure not found in Query Designer

Hi Experts,

I never faced this situation and still trying to understand the logic behind this mystery. Using a query for more than 2 years and was working fine until recently. One of the key figures is not found in the Query Designer (which was there all the time). This Key Figure is an attribute of 0PROFIT CENTER. Recently, business changed the hierarchies of profit center and ever since this Key Figure is  not found in the Query Designer, completely disappeared from under Key Figures folder. As a result the query is throwing an error. 

Hope someone has gone through a similar situation.
