You can write data to InfoSources when you run a PowerCenter workflow. The PowerCenter Integration Service can load data into two types of InfoSources:
InfoSource for transaction data.
Load data that changes often and is dependent on master data into an InfoSource for transaction data. For example, you can assign transaction data about sales development to a vendor’s master data and use the transaction data to determine the total sales of a vendor.
InfoSource for master data.
Load frequently-used data that remains constant over a long period of time into an InfoSource for master data. For example, the master data of a vendor may contain the name, address, and bank account information for the vendor. Create an InfoSource for master data when you want to load data into an SAP BI hierarchy.
