Where are other SAP applications headed with SAP S/4 HANA

Convergence of SAP Business Suite

SAP S/4 HANA is a simplification of SAP ERP. The product is not a complete replacement of ERP yet. It began with simplification of finance code of ECC, with Simple Finance. In other terms SAP has replaced the code meant for the finance piece in ECC with a code that takes advantages of the technical capabilities of HANA and ignores other databases. This means that that code will only work on SAP HANA database.

SAP is slowly simplifying other modules. Slowly the ECC part is being replaced by S4 Core.

Now that S/4 HANA is not a complete replacement of ECC, it will have the other modules using the same old code, written on ECC, compatible with all the DBs. This way S/4 HANA stays as a compete product as ECC is.

Does this mean that everything is being replaced? Apparently not. SAP has Succesfactors as its strategic HCM solution. So it will continue to develop HCM part in the compatible way (that works on AnyDB and HANA)

With the evolution of S/4 HANA, the other SAP products are also evolving. Some of the features will be implemented in S/4 HANA and for the parts not implemented, there is a target product.

The following diagram from SAP Teched depicts how the future SAP landscape is likely to change.

From Business Suite to S4 HANA

OS/DB Migration - CMD. STR, TOC, EXT, R3load, DDLDBS.TPL and more

Image
With increasing need to improve performance or reduce costs or vanishing support for operating systems/databases it becomes inevitable to migrate to a better OS or DB. We feel take a quick look at the primary ingredients of the tools for OS/DB migration handled by R3SETUP. Tools - R3load, R3ldctl and R3szchk R3ldctl creates STRucture files, TemPLate files by reading the technical settings for table/indexes in SAP data dictionary. R3szchk calculates the database size object sizes (EXTent files) for the target system based on the STR files created by R3ldctl. The EXT and STR files can be later split into smaller groups. The most crucial tool R3load is responsible for unloading and loading data from the database. R3load uses the files created by R3ldctl and R3szchk and dumps the data into compressed binary format as .001, .002 .. files. It uses cmd files to achieve the task. If the cmd files are not present, it creates on its own. Files Command files*.cmd  are created i

Fixing Inconsistent Table - Table activation fails due to inconsistency between DD and DB

If you find a table to be available on the database, but not active in ABAP dictionary, try calling SE14 as DDIC user, enter the table name and choose Table > Reconstruct, Execute. If this method fails follow these steps: Call transaction code SE37 and execute the function module  DD_TABL_ACTM with single test On the next screen, do not change any other field except the following and set them as shown below: MODE: 12 NTAB_PUTSTATE: N TABNAME: <enter the correct table name> Click on Execute The export parameter ACT_RESULT should show 0. To verify if the inconsistency is fixed, call transaction SE14 > Extras > Database Object > Check and  SE14 > Extras > Runtime object > Check.

301 Redirect Using SAP Web Dispatcher

301 redirects are typically used to redirect accesses that include www to non-www or vice-versa. Example, when you call http://blogger.com, the call is redirected to www.blogger.com. An end-user may prefer to call a URL in any manner. You must ensure that all these calls are redirected to relevant URLs with content. SAP web dispatcher can be configured to send a redirect (301) to the client. To enable redirection add icm/HTTP/redirect_<xx> to the web dispatcher's profile file. The parameter uses the following syntax: icm/HTTP/redirect_<xx> = PREFIX=<URL prefix>[, FROM=<pattern for URL>, FROMPROT=<incoming protocol>, FOR=<pattern for host name:port>,TO=<new URL prefix>, PROT=<protocol>, HOST=<host>, PORT=<port number/name>] Let's say you want to redirect all the HTTP requests on mysource.com on 80 port to mytarget.com on HTTPS 443 port icm/HTTP/redirect_0 = PREFIX=/, FROM=*, FROMPROT=http, FOR=mysource.com:80,
