I recently converted my database from RootsMagic 6 to 7 so this problem could have existed prior to RootsMagic 7. I have turned on the option to include RINs when viewing people.
When running a source list report I notice that persons' RINs are missing from the report output when the event/fact is "Alt Name". For example,
Sims, Irena (Name). FamilySearch.org; www.familysearch.org; Union County, Indiana||Union Co., Ind.; Harmony Township; pp. 759-760 (penned), pp. 717-718 (stamped); 1156; 1164; John Symms [Sims]; downloaded; 22 August 2013; 176
Should be
Sims, Irena-294 (Name). FamilySearch.org; www.familysearch.org; Union County, Indiana||Union Co., Ind.; Harmony Township; pp. 759-760 (penned), pp. 717-718 (stamped); 1156; 1164; John Symms [Sims]; downloaded; 22 August 2013; 176
That is, her RIN, 294, is missing from the output of the Source List report. It's like that for other persons on the report as well.
