    Hello,

    DATASOURCE

    A DataSource is a set of fields that provide the data for a business unit for data transfer into BI. From a technical viewpoint, the DataSource is a set of logically-related fields that are provided to transfer data into BI in a flat structure (the extraction structure), or in multiple flat structures (for hierarchies).

    INFOSOURCE

    Definition

    A non-persistent structure consisting of InfoObjects for joining two transformations.

    Use

    You use InfoSources if you want to run two (or more) sequential transformations in the data flow, without storing the data again.

    If you do not have transformations that run sequentially, you can model the data flow without InfoSources. In this case, the data is written straight to the target from the source using a transformation.

    However, it may be necessary to use one or more InfoSources for semantic or complexity reasons. For example, you need one transformation to ensure the format and the assignment to InfoObjects and an additional transformation to run the actual business rules. If this involves complex inter-dependent rules, it may be useful to have more than one InfoSource.

    Regards,
