How to remove SUPPRESS and null in mapping contexts

Hi,

I am trying to find a way to suppress context changes (SUPPRESS or <null>) in a mapping.

To understand, this is what I get in my context :

And here is what I want as a result (I modified the test data to get this) :

I tried many UDFs like this one but I can't have the result as expected.

The result of this kind of UDFs is that I have a <null> instead of SUPPRESS but still don't have the expected result :

As I have n values in different contexts, I can't use a simple "removeContext" and "splitByValue"...

I hope my request is quite clear and somebody can help.

Thank you,

Jeremy.
