Diference between Standard DSO and Direct Update DSO when using planning-Enabled, BPC 11.1, HANA 2.0

[cristina_ungureanu]

Hello Experts,

Which is the difference between Standard DSO and Direct Update DSO when using planning-Enabled?

It is wrong to use Standard DSO with planning-Enabled?

I have designed a model using standard DSO and we have some memory issues in hana, the Pool/PlanningEngine get blocked, the memory is not released after save and close of the workbook. Can be related with the type of the ADSO?

I will appreciate the answer of an expert.

Thank you in advance,

Cristina

Hi Cristina, how is the planning on Standard aDSO going? Do you still use it? Do you see any benefits over the Direct-Update aDSO?

Hi Cristina,

Are you still seeing the issue?
If yes, have you checked SAP note ##1999997 - FAQ: SAP HANA Memory.
In this note, it provides more details about this allocator and some possible solutions.

Best regards,

Hello,

The post is very old, but I hope it can help others in the future: I have redesigned the model by switching to a Direct Update DSO, and it works perfectly.

Technically, it’s not wrong to use a Standard DSO with planning-enabled functionality. However, it’s not optimal in terms of performance. The activation and change log processes can lead to performance issues, particularly in scenarios with high-frequency data updates, like planning.

Best regards.
