Step by Step how to change the table name

I have trouble each time. I have a table named tableA i wrote the crystal report against this. THen I found out this name is used in another database in our system. So I want to change tableA to tableACR.

I cannot RENAME at database expert because it removed all the program coding.

I have added tableACR and tried to ignore tableA but this too does not work.

Can someone list the steps how to simply change the name of a table in a current Crystal Report without losing all your coding?
