I believe they store a hash-table of the selected keys (ObjectiDs?). These seem to disappear when the layer is changed, so then everything is selected. I have never heard of the wrong records being selected, but it would make sense that that happens sometimes too.</P><P></P><P>Next time, you could try exporting the keys of your chosen records to a file, then using a join to do your selection from your original file. This is kludgy, but reliable.</P></BODY></HTML> Wed, 02 Mar 2016 01:23:12 GMT https://community.esri.com/t5/mapping-questions/repair-data-source-to-selection-layers/m-p/75772#M902 DanaNolan 2016-03-02T01:23:12Z Re: Repair Data Source to Selection Layers https://community.esri.com/t5/mapping-questions/repair-data-source-to-selection-layers/m-p/75773#M903 <HTML><HEAD></HEAD><BODY><P>Yeah, I believe I just quickly created layers from selected features. Thank you for the tip, I definitely learned my lesson!</P></BODY></HTML> Wed, 02 Mar 2016 16:55:11 GMT https://community.esri.com/t5/mapping-questions/repair-data-source-to-selection-layers/m-p/75773#M903 CamillaKaramanlis 2016-03-02T16:55:11Z
