⟩ When looking at the join types in Crystal - what does it mean when you coose Enforce and Enforce To or Enforce From?
Version 10 introduced the capability to enforce link created in report. Enforcing a link between two tables ensures that the report's respective SQL uses this link, regardless of whether fields are required from one or both the involved tables.
The default setting is unenforced links, meaning that Crystal Reports uses the link only if the report's respective SELECT statement requires it.
You can access the different enforcement option by right-clicking on a link and selecting the link Options menu item.
