APDs and Open hubs Sending SAP

BW Data to 3rd

Party

Applies to:

NetWeaver SAP BW 7.0. For more information, visit the EDW homepage.

Summary

There are occasions when we need to send data to 3rd

party systems such as Teradata or Datastage from SAP BW system.

To achieve this, SAP has provided Open Hubs wherein we can define the containers to store data, i.e., either a flat file or a database table, and facilitate the extraction of data to 3

rd party systems through these systems.

In addition to this, certain requirements mandate sending status details along with the actual data to 3rd

party systems. One such scenario is described here along with the solution devised.

Introduction

There are occasions when we need to send data to 3rd

party systems such as Teradata or Datastage from SAP BW system.

To achieve this, SAP has provided Open Hubs wherein we can define the container to store data, i.e., either a flat file or a database table, store data in these containers and facilitate the extraction of data to 3

rd party

systems through these systems.

In addition to this, certain requirements mandate sending status details to 3rd

party systems along with the actual data.

One such scenario is described here along with the solution devised:

Requirement:

Facilitating the status details for the latest load into the Master data Open Hub for Profit Center. In other words, we have an Open Hub defined, ZPFT_CTR, to send the profit center master data from SAP BW to 3

rd party.

Now 3rd

party also requires SAP BW to send the latest load details such as:

1. Request ID for the latest DTP run which extracts data from SAP BW target and stores it into the Open Hub.

2. The no of records extracted with the latest run. 3. Calday 4. OHD Name

Solution:

To cater to the above requirement, we can use a combination of APD and Open Hub. APD: The Analysis Process Designer is a graphical tool for modeling multilevel "Analyses Processes". It is an interactive modeling (drag & drop) workbench for multilevel Data Analysis Processes APDs empower us to do the following: 1. Creation of new information out of existing data 2. Transformation of data 3. Writing back new data to BW database or operational system (CRM) With APDs Different kinds of sources allow the possibility of ad-hoc analyses. We are going to leverage this feature by taking a standard SAP table as a source and storing the data in a DSO.

APD: This APD will take the standard SAP view for DTP, RSBKREQUEST_V, as source and store data in a direct update DSO (APDs only support direct update DSO) or Flat file.

Note: We could also use table RSBKREQUEST for DTP details but not all fields in this table are linked to data elements which is a mandate for using this as a source in APD.

Thereafter we can send data from the direct update DSO or flat file to another Open Hub which will store the status information for the 3

rd party.

Therefore in essence, we need to create the following objects in BW: 1. Z info-objects for direct update DSO. 2. Direct update DSO 3. APD 4. Open Hub for status details

Step by Step Solution:

Step 1: Create Z info-objects for direct update DSO.

Here we need to create 3 Z info-objects:

a) ZDTPREQID – This will store the latest DTP request ID. Data Type NUMC

Length 10 (The length of DTP Req in RSBKREQUEST_V view is 4510).



© 2011 SAP AG 5

b) ZOHDNAME – This will store the OHD name. Data Type NUMC

Length 45 (The length of target object in RSBKREQUEST_V view is 45)

c) ZOHRCDTRS – This will store no of records transferred to OHD Aggregation will be default (Summation)



© 2011 SAP AG 6

Step 2: Create a direct update DSO which will act as the target for APD.

We need to create a direct update DSO with the Z info-objects created.

DSO: ZPFCT3PR Key field: ZDTPREQID (As this would be unique with every load) Data fields: ZOHDNAME, 0CALDAY, ZOHRCDTRS

Step 3: Create APD.

Now we will create an APD which will take the data from the view RSBKREQUEST_V and store in the direct update DSO ZPFCT3PR

Tcode: RSANWB 1. Create an new APD under the Generic folder:

2. We will drag and drop the “Read Data from Database table” icon to the right panel.

3. Provide the description and the database view name:

4. Now we need to inform the APD as to which DTP requests it has to pick.

For that we need to drag a filter, connect it with the DTP View – RSBKREQUEST_V and provide details (right click -> properties)

While providing details for this filter, we need to transfer the field, TGT – Name of data target for DTP, from the list of fields to the selection and provide value as ZPFT_CTR.

Actually what this is doing is that it is selecting only those records from the RSBKREQUEST_V view where the target is the profit center open hub. In essence the DTP which is feeding the Open Hub for actual profit center master data.

5. Now we need to select the latest run details for the DTP. To achieve this we will be sorting the data which is picked after the filter restriction: For that we need to drag the sort data icon, connect it with the OHD Name filter and provide details (right click -> properties)



© 2011 SAP AG 8

While providing details for this sort, we need to transfer the field, REQUID – Request ID for DTP, from the list of fields to the selection and check the box for the descending option.

This will bring the latest DTP run record on the top.

6. Now we need to write drag the ABAP Routine icon, connect it with the sort and write a small routine which will extract only the top row from the table.

Before providing the details for the routing, drag the DSO icon, provide details and connect it with the routine, this will ensure that both source and target structure for the routine are connected to it.



© 2011 SAP AG 9

Here are the routine properties: Source Fields: REQUID, TGT, LINESTRANSFERRED, TSTMP_FINISH Target Info-objects (Direct update DSO Info-objects): ZDTPREQID, ZOHDNAME, ZOHRCDTRS, 0CALDAY

ABAP Code: Please see the ABAP code at the end.

7. Now assign the target info-objects to the source fields in the transformations from routine to the DSO

8. Now the APD is ready to be activated. Save and Activate the APD:

While saving please provide the technical name and description: Tech Name: Z_APD_MSRT_DAYA_3RD_PRTY Description: Profit Center (Attribute) Load details for EDW



© 2011 SAP AG 10

Step 4: Create an OHD for storing data for the latest DTP run.

This OHD will extract data from the direct update DSO ZPFCT3PR. Select database table as destination type.

Select database table as destination type.

Step 5: Create the Transformation and DTP from the Direct Update DSO to the Status OHD.



© 2011 SAP AG 11

Step 6: Test by Executing the APD and Checking Data.

For this first we will trigger the DTP which loads data from Profit center master data to the Open Hub - ZPFT_CTR.

This DTP generated Req ID – 111213 No of data transferred = 2462 Day of run - 22.04.2011 Target OHD – ZPFT_CTR



© 2011 SAP AG 12

Let’s trigger the APD and check the data in the OHD

Now execute the DTP from the direct update DSO ZPFCT3PR to the Open Hub ZPFCT3PR

Let’s check the data in the OHD table /BIC/OHZPFCT3PR We can see that data is accurately transferred from RSBKREQUEST_V view :

Now 3rd

party can access these details. These details can be used for reconciliation purposes such as comparing no of records extracted from the main OHD and no of records extracted from this status OHD.
