a) Remove Contexts: - remove all higher level contents of
the source level message in order to map with the target
message field. So you can get the node contexts removal.

b) Split by value: - Insert Context change for an element
split by value is some as counter part of remove context.
Here instead of delivering the context you can insert a
context change in the source value queue.
c) Collapse contexts: - Copies first values of the all
contexts to one context empty context are replaced by empty
string.
d) Copy Value: - How many ever times I occur I am copied
just once". This is not a node function but I am explaining
it as it is used very frequently in real-time. Let us take
an instance of material group, which can occur as many
times as the item node. But since we are mapping it to the
header in the target node I just want to copy the first
occurrence of material group and map it to the header node.
CopyValue exactly does that.
e) Create if: - It will create a target node or element
based on some condition.
f) Exists: - Function to determine whether a particular
source field exists in instance to be processed. If it does
it gives true or else false.
g) Use one as many.
h) Replace value: - Replace the value I with the value that
you desired in the dialogue for function properties.
i) Sort: - Sorts all values of the multiply occurring
inbound field with in the existing or set context.
