Thanks

Hi Narayana,

the differnece is the simple UDF take a values with occurance 1of type string as input and process and produces a tring value as output.

Advanced UDF takes entire queue as input and writes the value to this queue.

Simple function : Simple functions without paramters work like constants and produce the target element exactly once for each context.

if I use simple Functions (Which should be called every time and context, the target field should be build - in a single context) and advanced function(which should identify, depending on the result of the actual simple function call values from queued source fields) in a single element

Advance function : Advanced functions with paramters seem to produce the target element for each context

If you use advanced Functions, its little more complicate, then you have allready to provide a queue, which tells the advanced function - how many times to run and how how many result entries to create, 'cause these must match with the number of occurency of your target element (in simple words: you control the number of runs, that your single field mapping is processed)
