Update is not happening in Golden Gate

I have configured GoldneGate and Extract, Data pump and Replicat everything is working fine. However Update is not happening. Below are my Extract, Data Pump and Replicat file.

Extract File:

extract ext3
userid ogguser, password ogguser
exttrail /u01/app/oracle/product/11.2.0.4/ggsrc/dirdat/lt
DDL INCLUDE MAPPED
table gg01.t2;

Data Pump File:

extract dpump1
userid ogguser, password ogguser
rmthost targetGG, mgrport 7810
rmttrail /u01/app/oracle/product/11.2.0.4/ggtrg/dirdat/rt
passthru
table gg01.t2;

Replicat File:

replicat rep3
assumetargetdefs
userid ogguser, password ogguser
map gg01.t2, target gg01.t2;

Let me know, what parameters need to be configured to get update working.

Error which i get:
