I'm working with SAP / Informix and I want to be able to open an external informix database to get some data and process them in SAP with Native SQL.
Use ABAP EXEC SQL, to make the connection to your SQL database, and grab the information that way. To set this up will require working with your SAP Basis team to give SAP appropriate rights to your database. There are notes on what to do in OSS. Search for keyword DBCON in OSS.
