search/find in internal table.

Hi all,

I have an internal table that is filled with data to update business partners. We want it also to be possible to clear a certain field when updating fields. Those fields are filled with an #.

How can I search/find which table entries are filled with #?

I already tried the

 find all occurrances.... 

method, but that returns only the offset. I rather would see the fieldname of the internal table, so I can clear it.

regards,

Ron.
