Hi guys , 

I created one report definition in Assign-Worklist class. same report definition to fetch another value I joined work class and another class also.  

work class I mentioned prefix as CIN.

Same report definition I used as a table source. 

I used same property in table. 

property name CIN.Amount , that time column alignment is center but now requirement is left alignment. 

Now i need to change the left to center i am getting error message from pega end 

"Property reference CIN.Amount is invalid, as property Amount is not defined in class Assign-Worklist".

Actually, i created table and report definition long back ago in pega version 8.3.4

Now we upgraded 8.3.4 to 8.7.5 after upgrade i am facing issue. 

Please help me how to resolve this issue, i need to change lot of tables. every table having same issue.
