Exp() substitution with steady_state operator

Steady state
1

Dear all,

How do perform an exp() -substitution of gov rule correctly

G/STEADY_STATE(G)=((G(-1)/STEADY_STATE(G))^(gammaG))((BPI*STEADY_STATE(Y)/(Y(-1)*STEADY_STATE(B))))^((1-gammaG)*phiG)*eps_G;

I tried to:
exp(G)/(STEADY_STATE(G))=((exp(G(-1))/STEADY_STATE(G))^(gammaG))((exp(B)exp(PI)(STEADY_STATE(Y))/(exp(Y(-1))(STEADY_STATE(B)))))^((1-gammaG)*phiG)*eps_G;

I understand that the steady state of G is not log-linearized form, but could not figured out how to change it. Could you please give some suggestions.

Here is something inconsistent.
G is a log-level and \exp(G) is the corresponding level.

You are dividing the level by the steady state of the log-level.

If you have a steady_state_model-block you could define a variable GG=exp(G); if you already have the steady state of the log-level. Then you could use GG in your steady_state operator.

I changed it as below and it worked
Before I also forgot to take exponential of the shock

exp(G)/(STEADY_STATE(exp(G)))=((exp(G(-1))/STEADY_STATE(exp(G)))^(gammaG))((exp(B)exp(PI)(STEADY_STATE(exp(Y)))/(exp(Y(-1))(STEADY_STATE(exp(B))))))^((1-gammaG)*phiG)*exp(eps_G)
