JDBC sender adapter - 3 calls in PO 7.4

Hi Experts,

I have a scenario to fetch database records from ORACLE database using SAP PO 7.4 - JDBC adapter

There are 3 calls to make in order to fetch the data

a) Call a procedure before the fetch

b) fetch the record

c) Call another procedure after the fetch

How can we achieve this ?

thx

mike
