Checking status of cube behavior – BW4HANA

For overview on this topic and BW classic related specific information see following post: Checking status of cube behavior – BW classic.

In BW4/HANA based system there is no information about real-time behavior persistently stored in database like is in BW classic. Instead, the behavior (whether it is loading/staging or planning mode) is evaluated on the fly while user request the change of the behavior. For example if user triggers the behavior change system checks what real-time behavior is set currently and subsequently is changes it to opposite one.

Behavior change in t-code RSMNG:


Behavior change in BW Cockpit:


As the current mode is not stored persistently in database, it is hard to read it without access either to t-code RSMNG or to BW cockpit. However there is a way how to do it. To find out of aDSO is in planning or loading mode, query table RSPMPROCESS with selection:

 

PROCESS_TYPE                = PLAN

PROCESS_ID                    = */CPMB/ARI* //your planning enabled aDSO object

 

Then sort a result set via field PROCESS_TSN and check value of PROCESS_STATUS field. If it is Y means PLANNIG request is active in the aDSO thus whole aDSO is in PLANNIG mode. If the PROCESS_STATUS field has value G (Finished) means there is no open yellow planning request in the aDSO thus it is in LOADING mode. Logic that handles flipping of aDSO mealtime behavior is coded in ABAP class: IF_RSPLS_ADSO_API~SET_PLANNING_MODE (CL_RSPLS_ADSO_API).

From SAP NetWeaver to ABAP Platform

This post can be simply called as how SAP got from SAP NetWeaver (approx. 1997-2020 even till end of 2030 if we count extended maintenance) to ABAP Platform (2018 or 2019 onwards). This includes relations between all NetWeaver components like SAP Kernel, NetWeaver/BASIS/ABAP component/ABAP platform and corresponding ERP version (on-premise only).

In past there was an SAP term SAP NetWeaver, which was (still is) an umbrella term for SAP’s software stack. It represents an underlying technology component that provides a runtime environment for many SAP applications. Its roots goes back to year 1997 where it started as an internet portal technology (JAVA stack). Afterward an ABAP stack was added into NW Application Server. Other components were added meanwhile too (e.g. Business Warehouse (BW), Enterprise Portal (EP), Process Integration (PI)/Process Orchestration (PO), Master Data Management (MDM), etc.). Thus, it can be called as product family term. Over the years its name was changing. From SAP Web Application Server (although Application server is just a component of NW, this was during a times of SAP R/3 Enterprise) to just SAP NetWeaver. Then to NetWeaver 2004 (mySAP ERP 2004, SAP ECC Core). Subsequently to NetWeaver 2004s (SAP Business Suite). Followed by a name NetWeaver 7.0 (SAP ERP 6.0). The NetWeaver 7.0 had its versions: 7.01, 7.02, 7.03 and 7.31. Next major releases was NetWeaver 7.4 and NetWeaver 7.5. From 7.5 was first release to be used for next generation of *4 products like S/4 (SAP S/4HANA), BW/4 (SAP BW/4HANA). The NetWeaver 7.5 has its versions: 7.50, 7.51 (Innovation Package) and 7.52.

The SAP NetWeaver reached its maturity level and now it is not being developed any more. Instead, it is being transitioned to ABAP Platform. The new ABAP Platform is the foundation of the S/4HANA products starting with S/4HANA 1809.

For details on how long classic SAP NetWeaver will be supported refer to my blog post Life after life of SAP NetWeaver and Business Suite/ECC.

Below is an overview table that depicts a relations between SAP Kernel, NetWeaver / BASIS  / ABAP component  /ABAP Platform and corresponding ERP version with almost all its versions. Notice that are on-premise versions only.
