SAP R/3 -- PI -- Oracle DB SYNC (JDBC)

Question

What is the best approach to handle the following request:
We need to develop a synchonous call that will pass information from SAP R/3 through PI to an Oracle database can return the data.
For instance, we want to pass a material number from SAP R./3, and have all the related information stored in the Oracle DB returned immediately.
The data stored in Oracle will be retrieved via a JDBC connection.   If possible can you provide an example....thx

Answer 1

>> Just a simple query, no updating is required.
>>>  select f1 f2 f3....from ms_tbl where part = inbound-part
Then you dont need sql stored procedure . We can easily handle at pi side.
Step 1) create data type for proxy as per your need
Step 2)  Create the data type for  jdbc request side as similar below ...
<stmt>
    <Customers action="SQL_QUERY">
      <access> SELECT f1,f2,f3 from ms_tbl  WHERE PART ='$KEYFIELD$';</access>
      <key>
          <KEYFIELD>inbound-part</KEYFIELD>
      </key>
    </Customers>
  </stmt>
Note: use constant to populate values for action and access field in mapping area.
Step 3)
create data type for the  jdbc response side as below
<stmt_response>
<row>
<f1>
<f2>
<f3>
</row>
</stmt_response>
Step 4)
Then create Proxy response data type
Step 5) create message types and Service Interface.(outbound synchronous and inbound synchronous)
step 6)first map: Map step 1 messg type with step2 mesg type
step 7) second map:  Map step 3 mesg type to step 4 mesg type
Integration Directory: configure Jdbc reciever. Rest are all same.
That's  it.
