Scheduling dependecies in SAP HANA

Hello Experts,

We have created flowgraphs in SAP HANA. How can we handle dependencies for scheduling. For example:

I have three flowgraphs : A, B, C. I want to first schedule A and B should start only if A has successfully completed and the same case for C.

Hello Nishanth,

in the new XSA based WebIDE you can create a Task Chain in a Data Warehouse Project ( https://help.sap.com/viewer/6d568ed106704106914ab3971505811d/2.0.1.0/en-US/67da3a67b91d4d4c98d04d570cba7243.html ) and schedule your flowgraph dependencies, as the flowgraphs are one of the available task types there.

You could builds something like this:

Start -> Flowgraph 1 \

-------------------------------Last -> Flowgraph 3

Start -> Flowgraph 2 /

This would execute Flowgraph 1 and 2 and when both are (successfully) finished it will trigger the execution of Flowgraph 3.

Kind Regards,
Timo Wagner

Hi Timo,

this requires Data Warehousing Foundation (DWF) or?

Brand new, HANA 2.0 SPS01.

Does or should that work completely independent of ABAP BW 7.50? Could not test yet, hence I am not sure. Some slide show that making DWF independent of ABAP BW on roadmap, others do not.

Thanks, Clemens

Hi Clemens,

AFAIK the NDSOs that the DWF provides are by itself independent and the logic has been implemented in XSA.
If you just need the NDSO or scheduling capabilities you don't need an existing ABAP BW running on the landscape.

Kind regards,
Timo Wagner

Hi Timo,

Thank you for your reply. We are not using new WebIDE, the reason for not using new WebIDE is that we don't have option to create file in the flowgraph. Can I import the flowgraph I have created using HANA studio or workbench in new XSA based WebIDE?

Thank you,

Nishith
