IDOC and Invocation ID

[tomato]

the situation is like this:

In Server A, my job is trying to deliver 60k record into a IDOC stage (with an invocation id "ABC" for example), after more than 24hr, it is still waiting at the line as below:

<Jobname>.<IDOC stage name> : Using NLS map ISO8859-1

Eventually i stopped the job, and try with only 10 records in Server B (with same invocation id, "ABC"), it was working fine.

Then i export the job from Server B and import into Server A, and try to run for the same 10 records file, invocation ID "ABC". It hangs at the same line as before.

But when i run the job with the same 10 records file, but with invocation ID "EFG", it was ok!!!

How do i solve this? Please give me a hand as i am totally helpless here...

Thanks in advance....

P.S. both IDOC stage in Server A and Server B is pointing to the same SAP client.
