HOW DO I REASSIGN A PACKAGE VARIABLE VALUE FROM WITHIN JAVA BEANSHELL PROC

Question

Hi all
I am trying to something that I would consider quite normal in programming applications.
create a variable - systemId
create a procedure that runs some code (Java BeanShell), and then sets the varable to a value depending on that code
create a second procdure that runs some code(Java BeanShell), but uses the value of the variable set from the previous stage
In the package editor I have created a declare variable step, two procedures, and a flow: declare variable -> procedure 1 -> procedure 2
If I declare the variable with a vue of 10 initially then try #systemId = 400, I get an error along the lines of '10 = 400'
I am probably doing something basically wrong
regards

My friend it depends on you. What ever you mentioned that can be achieved in package level but in procedure level.
For example:
Odi procedure: Java beanshell techonlogy
<@
String empname="ALEX";
@>
odivariable1: refresh mode in package
select sal from emp where empname='<@=empname@>'
Package diagram:
ODIprocedure------ok--->ODIvariable inrefreshmode
if you will execute this then the odivariable will have value 2000( alex salary)
Till now it was easy to achieve. But tell me how to assign the alex salary inside the 1st procedure without taking the help of a package. You just have to execute only the procedure.Hmmm nail on your head ? you might be thinking of something like this #odivariable=<@=empname@> which is not correct.
In this scenario you have update the snp_var_data table. So that the underlying value can be updated. Another approach could be to generate a scenario of the odi variable given above and invoke the scenario inside the procedure(this way you can refrsh it without using a package)
Ok my friend. Seems to be a long explanation.
Let me know if it is helpful or not.
