I am running a process in FME 2014 to translate some data from an Excel to a PostgreSQL database. My created table needs to have two primary keys (thus a composite key). I have selected from the writer properties the columns which I want them to be PK but when I run the translation I get:
"Multiple primary keys specified in definition for table 'bom'. Only one primary key can be specified per table. Discarding primary key request for column 'item_code'"
How can I define composite keys in FME? Is it possible at all? If not, what are the alternatives?
