I've an export procedure that will call the QWVRCSTK api to

when calling from a RPG program. However, it failed (Returns
value of N in Information-status field) when it is call from
a sql UDF. Any idea why?

I believe that is the result of the SQL UDF running in its own thread. There is a clause on the CREATE FUNCTION which can minimize the chance the function will run in its own thread; IIRC it is the NOT FENCED clause which will encourage, but not require, that the SQL should run the function in the primary thread. The function runs in\from the LIC, thus no stack information will be available. If the primary thread of the job is being retrieved instead [of the thread dedicated to the function], then a similar origin [per threading] may be the cause, but it would most likely be that the primary thread is initially busy down in the LIC [e.g. starting new threads] such that repeated attempts might be required to obtain the information.
