Create Data Store in SAP HANA

 

Scenarios

Create Datastore for MYSQL DB

Login to DS Designer with local repository credentials

In Local object, worry go to Datastore (Tab)

Right-click and select new Provide DST Name  DSI Datastore

DST Type is a database.

DB Type MSSQL 2005

DB Server name DB

Name

User id

Password

Apply

OK

So will get stored procedures, physical tables, and template table

Double click on the physical table will get a list of tables which are related to our source database

Note: - We need to import only required tables rather than all tables to increase the performance

We can convert template tables to physical tables.

Create Datastore for SAP R3 ERP system

SAP ERP is recognized in DS as SAP Application DST. From SAP Application DS we call use metadata which is in the form of

• Extractors in 4.0
• Tables
• Function module
• Hierarchies
• /docs

The above metadata can be extracted & loaded unto SAP BW and any DB

   

Log on DS designer with local reposting credentials In Local object Library go to the data store (tab) Right-click add select row Provide Datastore name

•  Datastore type as SAP applications
•  Application Server
• Username
• Password
• System no
• Working directory on SAP Server                D:/ usr / sap / trans
• Application path to the shared directory      D:/ usr / sap/trans
• Data Transfer Method                                 Shared Directory
• Security profile                                            SAP – ALL
• NO of connections                                      3
• ABAP Execution option                               Generate & execute / execute Preloaded

NOTE:- Normally when you read the data from SAP R3 system it is recommended to use ABAP dataflow Over normal dataflow If we want to store ABAP programmers in SAP systems we can select execute preloaded Celebrate & execute option the system generated ABAP code resides on DS and it will be reused for executions Whereas if you select execute preloaded then the ABAP code will be generated and reminds at SAP APPL servers DS uses 4 different data transfer methods

a) Direct directory    Using DS Using RFC can

b) Shared directory  Using SAP Transports

c) FTP                       Using Remote Server

d) Custom Transfer   Using Auto Execute Program

Note When you don’t provide a surety profile DS will take SAP-ALL If we want to restrict we need to create a seared profile and provide here Ok After creating DS we can create metadata

a) Extractors   [Set of the data source provided by B1 content/custom]

b) Functions   [Set of functional mapping to ERP system is achieved by ABAP code this is reformed as a function module which can be extracted & loaded dumped into any forget SAP BW/Data based]

c) Hierarchies [During the preparation of the source system you map functional data to the SAP ERP system with a hierarchy

EX: - Cost center, GL amounts, eh, custom datastore

d) IDocs are preferred to load the data into the target system when we used to transfer the data file it is Sinclair to an on-directed staging area

e) Tables [SAP R3 DB tables]
