Is your system prepared to take advantage of MRP on HANA?

As I have explained on my previous blog MRP on HANA: What’s new?, as of SAP Enhancement Package 7 for SAP ERP 6.0, MRP was completely redesigned to take full advantage of the SAP HANA architecture.

Now there is a new MRP mode called MRP Live, which is executed on a different transaction and that can be much faster than the classic MRP. The new MRP Live is fully executed on HANA and, since it was built from the scratch, there are some scenarios that are still not covered by MRP Live. A complete list of these scenarios can be found on note 1914010.

As explained on my blog MRP on HANA: What’s new?, when MRP Live is executed and system finds one of these restrictions, it will automatically change to the classic MRP, where the database reading was optimized to be executed on HANA, but further processing is carried out on the old ABAP logic.

It means that all the materials can be planned on MD01N, even though they cannot be totally planned on HANA. However, in order to achieve the optimal performance on the MRP Live, we must try to avoid those restrictions, so that we can plan as many materials as possible directly on HANA.

In order to help you to estimate how many materials can be planned by MRP Live and exactly which restrictions do you have on your system, SAP delivered note 1975704, which contains report PPH_CHECK_MRP_ON_HANA.

This note is valid as of release 600 and this report is delivered on a support package, even on systems that are not using HANA. With this report, you can estimate the effort to improve your master data focusing a better performance on MRP Live after an upgrade.

The report provides a compact display, with the total number of materials that can be planned by MRP Live by low-level code, and also specifying the number of materials that cannot be planned by MRP Live for a specific restriction.


The report also provides a detailed display, where all the materials are displayed. Here, the report will tell you if the material will be planned in HANA or in ABAP and it will also tell you if there is any specific restriction for this material.


Therefore, if you are considering to use MRP on HANA, you can use this report to improve your master data and reduce the number of restrictions, focusing a better performance on MRP Live.

I also suggest you to take a look on the following note, which provides more information about the MRP on HANA performance:
