to set global variables

[former_member587006]

Hi All,

In my scenario I am using a global variable wherein i ahve to subtract a source field value from the global variable and set the global variable to that value.also return the same value.

How can i do it?Can any one help me writing the source code(UDF).

regards,

Vikram

Hi Karanam,

you can define global variables in message mapping.

Below Design/Test/Messagest tabs, we have some icons.

click on the right most icon (Edit Java Sections).

Here you can declare your global variables.

for ex String b;

below that you can initialize the variable like

b= "2";

and you can use this in your UDF.

for example if you say " return b; " in your UDF, it will return the value of b.

if you want to modify the value of b using the UDF as well.

for example, if you write,

b = "aaa" + b;

return b ;

it will return "aaa2".

dont forget to award points

Karanam,

I don't know whats ur initial Global Container Variable Value, Lets assume it as "10" and we will continue.

UDF:<b> Set Initial Global Variable.</b> //No Input parameters, map this UDF to root node of target

GlobalContainer gc= container.getGlobalContainer();

gc.setParameter("MyValue","10");

UDF: For your any target node u want to subtract.//No Input parameters

GlobalContainer gc= container.getGlobalContainer();

Integer local= Integer.parseInt(gc.getParameter("MyValue"));

int node_subtract = (int) local -2;

String setgc ="node_Subtract";

gc.setParameter("MyValue",setgc);

return ""node_subtract"";

Hope it helps!! Since the above code is not compiled, I just wrote in the fly u might get some object conversion-I think. But the logic is correct, repl back if u hav any queries.

Best regards.

Hi,

This helped me to some extent.

But i want to check the global variable once the value of that variable has been set.

in my scenario the file has to be sent for n number of times and after each transaction the global variable has to be set to a new value i.e,

(Global variable - a source filed value)

where the value of the global variable is the value set during last transaction.

Hope you understood my requirement.

Vikram,

<i>in my scenario the file has to be sent for n number of times and after each transaction</i>

Are u sending files to target system multiple times, and after each transaction u want to decrement am I right? If yes its not possible vikram.

Hi,

I can suggest you some unconventional ways of doing this.

you can store this value in some table on abap stack of XI.

In your mapping you can write a udf to do a JDBC to fetch the value and update the value directly.

Else,

you can also create a fn module which in has an input and output parameter.

you can pass the input value to update the filed and export to get the value of that field..

I mean you can do whatever you want

and call that in your UDF to return that value.

If you need to have relation between different transactions in the process, you need to use BPM.
