    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi all !&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I'm trying to load some files with same structure (106 fields... ... ...) by using the Data manager. Each files contains data for a month.&lt;/P&gt;&lt;P&gt;Refer to &lt;A href="http://help.qlik.com/en-US/sense/3.2/Subsystems/Hub/Content/LoadData/managing-data.htm#anchor-8" title="http://help.qlik.com/en-US/sense/3.2/Subsystems/Hub/Content/LoadData/managing-data.htm#anchor-8"&gt;Managing data in the app with the Data manager ‒ Qlik Sense&lt;/A&gt;, there's no pb to do this.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I began by added 1st file.&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-size: 10pt;"&gt;Then I added added the 2nd file.&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;The result is :&lt;/P&gt;&lt;P&gt;2 sources&lt;/P&gt;&lt;P&gt;Each field is now prefixed by source name&lt;/P&gt;&lt;P&gt;Sense generate a Synthetic key with the 106 fields !&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;When analyzing the result with the data model, I understand what happend :&lt;/P&gt;&lt;P&gt;3 fields of this file are understand as geographical data =&amp;gt; At this time, no new fields appears with coordinates.&lt;/P&gt;&lt;P&gt;When adding the 2nd file, Data manager understand the 1st table WITH the futur new fields.&lt;/P&gt;&lt;P&gt;So Synthetic key, Prefixing fields, ...&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;My way to correct :&lt;/P&gt;&lt;P&gt;After loading the 1st file, I change the type of the 3 fields understanding as geographical data (I say that it's standard data).&lt;/P&gt;&lt;P&gt;When adding the 2nd file =&amp;gt; No pb ! Both files are concatenated.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I personnaly see that as an issue because this geographical data don't exists when preparating data..&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I hope I was clear and someone can tell me if I made a mistake or not.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;thanks for you attention !&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
