Sequence Number in XI Mapping

Question

Hi All,
I have scenario where a sequence number when mapping is done. Consider the example:
In the source message I have one header and 10 line items in the message. The line item in the target message has a field called sequence number. When i map the source message to the target message each of the target line items hould have a sequence number in the order 1, 2, 3..10.
How can this be done? Is there a feature in XI which lets us have a global variable which can be incremented for each line item or a java class which can generate new sequence number for each line item or something.
I'm using message mapping. Java mapping is not used.
Could you please help me?
Thanks,
Sandeep

Hi Sandeep,
u can follow these steps to generate a sequence no using global container.
-> define a global variable by clicking the JAVA_SECTION_TOOLTIP icon on the design tab of source message type of ur message mapping.
enter the following in the GlobalVariables Section
Integer counter =0;
-> define a user defined function (<b>SeqGen</b> let's say)
write the following code in it.
Integer seq = 0;
GlobalContainer globalContainer = container.getGlobalContainer();
a = globalContainer.getParameter("counter");
seq = globalContainer.getParameter("counter");
seq = seq + 1;
globalContainer.setParameter("counter",seq);
return a;
now use this user defined function (SeqGen)in all ur mappings to the sequence no of ur line items.
Hope this helps.
