Welcome to the communtiy of Information Steward users!
Please make yourself familiar with the concepts and the product tutorials we have created for SAP Information Steward and made available here on the SCN:
SAP Information Steward 4.x Product Tutorials
Ther eis e.g. a Getting Started section with a tutorial on Create Connections, Import table metadata, Import file metadata, ...
Your start was perfect, you have create a user, a project and during installation you have created a IS repository (which stores all the IS project information, rules, calcualted scores etc.).
But for accessing any data (database tabels or files) to do a profiling or a data quality assesment task, you have to go first to the CMC and in teh Information Steward section you have to define the database connection TO YOUR SOURCE DATABASE (that includes e.g. dbuser, password etc.) and then in the "Add table" screen within the Information Steward you wil see on the left hand side the selection of the already defined database connections that are visible (granted by the administrator) for you as an IS user. There you will be able to select then the tables form the database that you want to add to your project.
Hint: After you have checked which tables you want to add to your project from that database connection please do not forget to press the "Add to Project" button on th eupper left corner. when you check the tables and just "Close" the window they will not be added.
