Business Function works on Fat Client but not Web

Opened a case but thought I would post this here also in case anyone else has had this problem:

For a custom extract I am doing I wrote a UBE and need to not have commas or semi-colons in the file as those are used as delimiters. To remove them I use B989460 - ReplaceValueInString and replace them with a space.

The business function works fine running it on a fat client in the DV environment and in PY after the project was promoted. It does not work on the web client.

In the debug log from the web you can see that it does not seem to have the data structure, D989460B, for the function. In the debug log for the fat client it does look like it is there.
