Identify the export/filter in question

Does the export/filter come from the base or from one of the joins?

Deactivate multiple query parts at once

Hold down Control (Windows) or Command (Mac) and click an export to select it and as many others of the same kind as you want, then click the Deactivate icon at the right and confirm.

You can also use Control/Command + Shift to highlight every export, filter, sort or join in a sequence.  

Check the underlying data

• Does the data actually exist on the record? Use the GUID, Reference ID, or Key filter on the base to identify a specific record you know has the appropriate data to help streamline the troubleshooting process.

• Do the appropriate export values exist? If you are selecting export values, do the associated prompts all have appropriate export values?

Have the field settings changed?

Have any of your users recently changed any of the settings on the associated custom field? These changes can break existing exports/filters and is noticeable when only some of your records export data but others do not.

Are there any additional restrictions imposed by the query base?

The most common example is a population-aware query base where a user's permissions affect which applications they are able to query.

Slate limits all query rows to 64KB, so make sure your exports aren’t returning extremely large values.
