2) Create Data store 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

  1. Extractors in 4.0
  2. Tables
  3. Function module
  4. Hierarchies
  5. /docs

The above metadata can be extracted & loaded unto SAP

BW and any DB

 

Create Data Store in SAP HANA

 

Log on DS designer with local reposting credentials

In Local object Library go to data store (tab)

Right click add select row

Provide Data store name

  •  Data store type as SAP applications
  •  Application Server
  • Username
  • Password
  • System no
  • Working directory on SAP Server              Screenshot_24 D:/ usr / sap / trans
  • Application path to the shared directory Screenshot_24  D:/ Usr / sap / trans
  • Data Transfer Method                                 Screenshot_24Shared Directory
  • Security profile                                               Screenshot_24SAP – ALL
  • NO of connections                                        Screenshot_24 3
  • ABAP Execution option                               Screenshot_24Generate & 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

Cerebrate & 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 generated and reminds at SAP APPL servers

DS uses 4 different data transfer methods

  1. a) Direct directory Screenshot_24Using DS Using RFC can
  2. b) Shared directory Screenshot_24Using SAP Transports
  3. c) FTP                         Screenshot_24Using Remote Server
  4. d) Custom TransferScreenshot_24Using Auto Execute Program

 

Note

When you don’t provide surety profile DS will take SAP-ALL

If we want to restrict we need to create seared profile and provide here

Ok

After creating DS we can create metadata

  1. a) Extractors Screenshot_24[Set of data source provided by B1 content / custom]
  2. b) Functions Screenshot_24[Set of functional mapping to ERP system is achieved by ABAP code this is reformed as function module which can be extracted & loaded dumped into any forget SAP BW/Data based]
  3. c) Hierarchies Screenshot_24[During preparation of source system you map functional data to the SAP ERP system with hierarchy

EX: – Cost centre, GL amounts, eh, custom data store

  1. d) IDocs Screenshot_24are preferred to load the data into target system when we used to transfer the data file it is Sinclair to on-directed staging area
  2. e) Tables Screenshot_24[SAP R3 DB tables]
