LINQ Statement - what data is available to each company?

All of the data for our configurators is stored in our main company’s (200) UD01 table. Our other companies use this data in their configurators as well, since our products are the same across different companies/locations. This all works appropriately in our existing configurator.

I am rewriting some of the logic, but it seems that all of the data from UD34 (a new table for testing purposes) is unavailable in any company other than company 200 (where it was created), even though I do not use a company filter in my LINQ statements. Any ideas why this may be? The only major difference between the existing configurator and my logic is that UD34 uses extended UD fields while UD01 uses the standard field options (Number01, Number02, etc.).
