In SAP Note1914010 http://service.sap.com/sap/support/notes/1914010
MRP Live has defined as follows:
MRP Live on HANA (MD01N) was implemented to improve MRP performance on HANA. This has been achieved by implementing application logic in SQL-Script which runs on the database server. That is, the MRP transaction has been completely re-implemented. This is a large project and the plan is to pursue a step-by-step approach: Every quarter, additional planning features are implemented in SQL-Script. However, the aim is not to re-implement the complete scope that is currently covered by the classic MRP transaction. The classic MRP run (MD01) also runs on HANA (parallel to MD01N) with exactly the same functionality as on any other database.
All restrictions and comments were made based on SAP_APPL component in this note. Now I decided to see how it will work with new component called S4CORE, because this component has Logistics and Financial db simplifications and new code-line.
First of all I want to check if my materials are available or compatible for MRP Live. So I run the program PPH_CHECK_MRP_ON_HANA
I have seen that all MRP related materials are subject to MRP Live.
Now it is time to tun MRP on HANA by MD01N
I have run for all Materials for plant 1000 (only 4 )
I really like the way it runs, on the left bottom, there is an information progress bar, shows the low-level calculation code progress.
Once the MRP Run finished, Performance log appears: If MRP Levels button is clicked then detail log can be seen.
Stock/Requirement list is used to see the summary of the MRP Run.
And the detail list shows the requirements and created PurReqs
MRP Live on HANA by S4CORE component is stable and runs well without any runtime errors despite logistics simplifications.
