Description When you perform a &ldquo;DeleteAll&rdquo; when there is nothing to delete, it will still perform a lock. When you for example perform a DeleteAll on an empty table, it will result in a table lock. Therefore it&rsquo;s good practice to always check if the table is empty when performing a DeleteAll.

Bad code EmptyTableWLD.SetRange(Code, &#39;AJ&#39;); EmptyTableWLD.DeleteAll(true); Good code EmptyTableWLD.SetRange(Code, &#39;AJ&#39;); if not EmptyTableWLD.IsEmpty() then EmptyTableWLD.</description></item><item><title>Subscriber Codeunits</title><link>https://alguidelines.dev/bcbestpractices/performance/subscribercodeunits/</link><pubDate>Mon, 01 Jan 0001 00:00:00 +0000</pubDate><guid>https://alguidelines.dev/bcbestpractices/performance/subscribercodeunits/</guid><description>&lt;Created by waldo, Described by waldo&gt;

Description In general, subscribers have to be put in codeunits. There are a few performance considerations that you should keep in the back of your minds, when designing such a codeunit.
|
|
Keep the codeunit as small as possible Work with a single instance codeunit only subscribe when necessary Avoid generic OnInsert/OnModify/OnDelete Let&rsquo;s discuss all points
|
|
Keep the codeunit as small as possible Every time a subscriber gets called, a new instance of the codeunit is being loaded in memory, which takes memory and processing power.</description></item></channel></rss> |
