Creating a Parameter

Use Parameters to allow users to enter values during the definition or execution of a Load Set, Data Mart, Program, or Business Area. You must create a defined Parameter object for each parameter required and handle the user input in your source code.

Parameter definitions are usually contained directly in the Adapter Area. Alternatively, if you are creating multiple adapters for a single external system and more than one of them use the same Parameter definition, you may want to create the Parameter definition directly in the Adapter Domain.

Note:

If you are creating an adapter that must upload files, define a Parameter with its Parameter Type set to either BINARY_FILE or TEXT_FILE, as appropriate, and create an instance of it in the runtime Parameter Set (see Creating a Parameter Set.) Create a second Parameter called TMP_BLOB_ID, for example, and create an instance of it in the same Parameter Set. Write code to upload the file to a temporary location and store the ID for the file as the valueof TMP_BLOB_ID. Use this value in your pre-execution function and execution function.

For details, see the following:

• Call the Create Parameter API
  
• Save the Parameter ID for Future Use
