How to remove NULL values from PI Message mapping

Hi! PI Guru's

I have been facing a problem of NULL Values being inserted when I get values back from RFC Look up Function Module.

When my RFC look up come backs with multiple look up (Designed RFC Function Module to pass multiple entries and return multiple enteries based on the link below)

I referred Shabarish Blog and designed the mapping accordingly.

However, the RFC is returning a set of NULL values between every result set - hence the mapping is insert BLANK values for alternate sets of look up values.

Is there any way I can remove these set of BLANKS result set so that the mapping does not map blank values and RFC values get returned correctly.

Not sure, if there is anything I can do in the RFC Function Module - so that these blanks dont appear at all in the first place whenever the RFC look up returns result set.

It will be of great help if you can let me know if can handle this in the PI mapping - by REMOVING the NULL values using node functions in PI mapping itself.

Your helps is greatly apprecaited!!

Thank you,

    try like this. Consider input is returned in the rfc output.

    input→ equals → not→if without else → Output

    Constant[] →

    Give input to if without function to be passed to output.

    If you get suppress in the output use the remove context node function.
