SAP's Accuracy

How Accurate Was SAP on MRP Performance on HANA?

Executive Summary

  • For years SAP has said MRP ran far faster on HANA than any other database.
  • In this article, we review the accuracy of this claim. 

What SAP Said About HANA Running MRP Faster than On Any Other Database

A primary argument put forth by SAP is that processor intensive activities, such as running MRP, would run faster on HANA.

See our references for this article and related articles at this link.

Hasso Plattner stated that due to HANA that there would be no more batch processes. This means that MRP should run instantaneously no matter what the size of the system. Hasso Plattner further stated that S/4HANA with HANA reduced the processing time of MRP for a Chinese company from 24 hours to 2 hours (although still not to zero minutes, which is what “no more batch processes” would mean).

What Really Has Been Happening with MRP on HANA?

There are several problems with this. The first is timing. We created a project plan to calculate that a period of 18 months would have elapsed from Dr. Plattner’s statement about the Chinese company to the date on which a company could run MRP in S4.

But there is a second problem. Information from the field, as well as lab results, show that HANA has performance problems in supporting MRP and underperforms MRP run on older versions. Purely row oriented versions of Oracle, IBM and MS. This is covered in the article MRP Performance Problems with HANA.

From our estimation, the story provided by Hasso about the Chinese company did not happen. It actually could not have happened. Furthermore, S/4HANA has performance problems with MRP at the time this research is published.

In numerous reports from the field, we have found HANA not only has no performance benefit over previous generation databases but significant performance problems running MRP.

This we covered in the article How to Interpret MRP Performance Problems HANA.

As is covered in the article why HANA is a mismatch for S/4HANA, and ERP, HANA is a poor match for ERP systems because it has shown to be inferior to previous versions of Oracle and IBM and Microsoft for transaction processing.

Conclusion and Calculation

SAP receives a 0% accuracy rating on MRP being either faster on HANA or MRP having taking no processing time with HANA.
