If you are using EBS 12 as a data source, you do not need a source adapter.
You simply choose to register a source system and select the type as EBS12 from the drop down and enter your ODI Context Code (GLOBAL) and save.
You can refer to the FDMEE 220.127.116.11.200 Administrator Guide for information on setting up the EBS 12 source system
Sorry for my bad description. I am not talking about the adapter. I'm asking the table name and column name in the Source Column area where is at the bottom of the page Source Adapter after saving the adapter follow your suggestion.
As Jeff mentioned, source adapter is not needed if you are using out of the box integration with EBS GL.
When you use a source adapter (for example Open Interface Adapter), you can select which columns of the table are going to be extracted and therefore you can use them in the import format. You can also assign an alias so you have a more readable name.
That meams nothing need to be input in both table name and column name, right?
They are already filled by default.
You would change if you had a custom adapter built.
Which source adapter are you working with?
