I stand corrected. :-)<br /><br />For this task, David&#39;s way is better.<br /><br />​​​​​​​Fernando

Instead of putting it in the structure, just use the expiration date on the article itself.<br /><br />Liferay will automagically expire it at that time and you won&#39;t need to do any custom coding.

Hi, <br /><br />I have to develop a module in Liferay DXP to delete journalArticles based on a structure field of those contents, the structure have a field called &#39;cancelationDate&#39; to determine when the Article is useless. From that date, the content won&#39;t show in the portal but will persist in BBDD. After a &#39;x&#39; days after that date, the article would be deleted from BBDD.<br /><br />I think about developing a cron job module to delete from BBDD those articles every sunday for example. I&#39;ve read the following post about cron jobs looking for some info:<br />https://community.liferay.com/blogs/-/blogs/liferay-7-ce-liferay-dxp-scheduled-tasks, but i don&#39;t know how to start.<br /><br /><ul style="list-style: disc outside;"><li>In the doRecive method is where i have to code the logic to find the articles to delete, right?
