Delta datasource management in process chain

Hi experts,

I have the following problem with process chains.

I have one <b>Delta</b> infosource used to load two different infoproviders (ODS1 and 2).ODS 2 must be loaded only once ODS 1 is loaded and activated. The Delta process implies that the <b>2</b> ODS are datatarget for the delta infopackage.

In my process chain, I have :

'execute infopackage IFPCK1'

<i>(with 'only PSA' option and of course the two datatargets ODS1 and ODS 2 selected)</i>

then a first

'Read PSA and charge datatarget process'

<i>(with options : datatarget = ODS 1, execute infopackage IFPCK1)</i>

followed by

'Activate ODS' ODS 1

then a second

'Read PSA and charge datatarget process'

<i>(with options : datatarget = ODS 2, execute infopackage IFPCK1)</i>

...

Each time, I run the Process chain, I have the following message for <b>ODS 2</b>

"the request <b>(ODS1)</b> already exists in infocube/ODS; Not loaded."

It is as if the first Read PSA process tries to load both ODS instead of only one.

Any suggestion to help me slve this problem ??

Thanks in advance

    Hi Daniel,

    unfortunately there is no easy way around this. I would suggest to create an ODS 3 as exact copy of the info source and load ODS 1 and 3 in parallel and then ODS 2 from ODS 3.

    Best regards

    Dirk
