String cannot be converted into NmCommandBean

[SHRI_HARI]

I was trying to get data from ServiceEffectivity to a String and I tried to convert it to NmCommandBean as shown in the figure. When I tried to compile it I am now getting a error as String cannot be converted into NmCommandBean. How should I solve this problem?
