From details :

2015-09-18 03:52:31 ERROR OGG-01920 Missing COMPARECOLS column <column_name> in before image, while mapping to target table <schema.table_name>. Add the column to GETBEFORECOLS.

Reviewing the Extract Report file, the configuration looks good. Supplemental Logging is enabled on all Columns.

When checked on the table DDL, there are virtual columns

TEST1 VARCHAR2(80) GENERATED ALWAYS AS ( SUBSTR("SPCL",INSTR("SPCL",'_',(-1))+1) ) VIRTUAL,
TEST2 VARCHAR2(4) GENERATED ALWAYS AS ( SUBSTR("ABC",1,1) ) VIRTUAL,
TEST3 VARCHAR2(480) GENERATED ALWAYS AS ( NVL(SUBSTR("ABC",1,INSTR("REA",';',1)-1),'ACT') ) VIRTUAL,
