Export DataSource: delta managing

Data loaded in <b>InfoCube 1</b> are currently updated in <b>InfoCube 2</b>, with a <u>delta</u> process.

InfoCube 1    ---->     InfoCube 2

Now I need to load<b> ODS 1</b> also from <b>InfoCube 1</b>, using a <u>delta</u> process as well:

InfoCube 1    ---->     InfoCube2
     |
     ------------>    ODS 1

Is this staging scenario feasible, even though <b>InfoCube 2</b> is <u>already provided with deltas</u> from <b>InfoCube 1</b>? (The scheduler has already got an init loading for that DataSource).

Thanks&Regards, Davide

    It should be feasible, note that it will probably deliver addictive delta so you'll have to care for this in update rules for ODS

    • Hi!

      1) Suppose I update the changes from <b>InfoCube 1</b> to <b>InfoCube 2</b>. As a consequence the next delta won't load any record in <b>InfoCube 2</b>.

      2) Then I initialize <b>ODS 1</b> without transferring any data. I need to request a delta to load it with some data.

      3) Now this very same delta will load lots of records in <b>ODS 1</b>, whereas no records will be loaded in <b>InfoCube 2</b> (see point 1).

      I'm wondering how the system can know which records needs to be updated in ODS 1 and which others in InfoCube 2 (none in this case). Is the process supposed to work in this way?

      Thank you, Davide
