For example, Customers or Sales Orders each could have a series defined so that all new Customers or Sales Orders get a new number automatically.</p><p>The Number Series system serves a few ancillary roles:</p><ul><li>maintains the usage information to know when the last number was generated and on which date</li><li>allows for date driven structures, so that different periods may have different structures</li><li>allows control of if manual entries are or are not permitted</li><li>allow for incrementing in different steps (+1 each time or +1000 each time)</li><li>warn users as a series is running out of numbers</li><li>control if any gaps in a series are permitted (as some regional laws do not allow skipping)</li></ul><p>This is many roles, features, and controls for generation of a single field so the implementation of this can seem difficult at first.</p><div class="alert alert-info" role=alert><h4 class=alert-heading>Note</h4>One additional (and somewhat optional) feature in the Number Series engine allows multiple sequences per type, called <strong>Relationships</strong>. For example, different numbers for Items that are finished goods versus raw materials. This requires additional hooks on the Page.</div><h2 id=usage-in-data-entities>Usage in Data Entities</h2><p>To understand an example use in the Base App, the Customer data entity is a good choice.</p><p>Implementation to connect the Customer <strong><code>No.</code></strong> field to the Number Series engine is done at the table level. The Customer table contains:</p><p>A field to contain the number (typically the primary key), which will be of type <strong><code>Code</code></strong>, length of <strong>20</strong>:</p><div class=highlight><pre tabindex=0 style=background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-AL data-lang=AL><span style=display:flex><span><span style=color:#204a87;font-weight:700>field</span><span style=color:#ce5c00;font-weight:700>(</span><span style=color:#0000cf;font-weight:700>1</span><span style=color:#000;font-weight:700>;</span><span style=color:#f8f8f8;text-decoration:underline> </span>&#34;No.&#34;<span style=color:#000;font-weight:700>;</span><span style=color:#f8f8f8;text-decoration:underline> </span><span style=color:#204a87;font-weight:700>Code</span>[<span style=color:#0000cf;font-weight:700>20</span>]<span style=color:#ce5c00;font-weight:700>)
