# Cue Table

Cues are the second usual application of the Singleton Table pattern in Dynamics NAV, after Setup Tables.

Context: The user gets overview information about the business on the Dynamics NAV Role Center page.

Figure 1 - Cue information in Dynamics NAV shows cue information seen by the user on the Sales Order Processor role center.

The overview information consists of summed-up numbers, calculated from business data, like for example how many sales orders are still open, how many shipments are ready to go, or partially shipped, how many documents are waiting for approval etc.

Problem: NAV stores data in tables. By definition, a table is a repetitive structure containing multiple lines, each line having a different piece of the information. But sometimes this repetitive information needs to be summed-up or otherwise synthetized, and presented as an overview.

Solution: Store overview information in a singleton table.

There are two ways of calculating overview information in NAV.

1. By using a FlowField. This applies for simpler calculations, like filtered or unfiltered counts, sums etc.
2. By writing C/AL code to perform custom calculations. Use this when:

- - The way to calculate the overview is too complex for flow fields, or
- The data needs to be pulled from an external system (like Dynamics CRM, QuickBooks or any external integration).

The implementation of Cues is already described in detail on MSDN, in Creating and Customizing Cues and in Walkthrough: Creating a Cue Based on a FlowField.
