I have an expression rule/function getgroupsformemberuser(ri!username). I believe this will return Group ids of that user (example: test: username: jsmith output: Group:[xxxen-USTelligent Community 12https://community.appian.com/thread/20316?ContentTypeID=1Wed, 15 Jul 2015 20:31:10 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:e8f4be92-dad6-455e-9b84-7069f02100f1batirbekmBah! It is working. I had space after semicolon! Thank you mschmitt! :)<div style="clear:both;"></div>https://community.appian.com/thread/20315?ContentTypeID=1Wed, 15 Jul 2015 20:22:54 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:ebf40bcd-1efe-4a02-b0ef-1a9928b63df7Mike SchmittWhen I test the same code in expression editor (using 2 valid usernames separated by a semicolon and no space), i get both users&#39; groups appended to one long list of groups. I&#39;m not sure why it wouldn&#39;t be working in your case but you might try checking to make sure nothing&#39;s been overlooked.<div style="clear:both;"></div>https://community.appian.com/thread/20314?ContentTypeID=1Wed, 15 Jul 2015 20:17:17 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:f6094462-1dc0-403a-8e61-99076345c398batirbekmYes, here is a sample code: <br />parameters: username, type text, multiple.<br />apply(fn!getgroupsformemberuser, ri!username)<br />Test: jsmith; asmith.

Is it still not working for you? If not, maybe you can post some example code here?<div style="clear:both;"></div>https://community.appian.com/thread/20308?ContentTypeID=1Wed, 15 Jul 2015 19:03:54 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:822b5a4c-7b0d-432a-9989-fc7b083310b0Mike SchmittIf you have a variable containing multiple users (ri!users for example) - off the top of my head, you can do this easily using apply() functionality, such as:<br />apply(fn!getgroupsformemberuser, ri!users)<br /><br />As a basic explanation, the apply() function takes another function and calls it once for every member of an array you feed it; the output is another array containing the results.<div style="clear:both;"></div>https://community.appian.com/thread/20301?ContentTypeID=1Wed, 15 Jul 2015 18:23:03 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:8c310bb7-980b-4fe3-b12e-388030c18016batirbekmRule input defined to be multiple - yes! No, I am not doing anything else. I see, I am using Type: Text not User. My output from my previous node is type text. I need to convert text to user object and then use this function. <br />Thank you again for your help, joshl!<div style="clear:both;"></div>https://community.appian.com/thread/20300?ContentTypeID=1Wed, 15 Jul 2015 18:09:22 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:85f32bc1-996d-499f-b2bc-466b7cbb75cdJoshThis works for me: &quot;apply(getgroupsformemberuser(_), ri!users)&quot; Is your rule input defined to be multiple? Are you doing anything else in your expression rule?<div style="clear:both;"></div>https://community.appian.com/thread/20299?ContentTypeID=1Wed, 15 Jul 2015 18:03:56 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:28ca01f2-e719-41bd-b896-525cd8040a2dbatirbekmThanks joshl!!! I tried to use apply function and it returns first user&#39;s group id. test: asmith; bsmith; output: only returns asmith&#39;s group ids.
