How to promote out of the box field from Child to Parent table?

[dvelloriy]

Hi Community,

I have an out of the box field "Version" on cmdb_ci_appl table.

We need to promote this field to cmdb_ci table. Any recommended way of doing that?

I know we have a method "GlideDBUtil.promoteColumn(sourceTable, targetTable, column) function call which i dont want to use as it is not recommended by ServiceNow and not sure if this would work in Madrid as per the below article.

Please advise.

Thanks in advance.

Did you happen to see the workaround options mentioned in the referenced KB article?

I am not sure I would recommend that given "version" exists on 236 extended cmdb_ci class tables.  Why do you need to move it up to the parent cmdb_ci table.  But regardless if you do create a new one it would be called "u_version" instead and you could create a fix script to populate the value from version into the u_version field and then have a BR that maintains both IF the version field exists in the extended class.

This is also a good "Idea" to submit in the Idea portal.

Please mark Michael Ritchie's reply as Correct. Even if it works, it is a bad idea to promote an out-of-box field.

hey hi

wanna try something as below:

function onBefore(current, previous) {

    //This function will be automatically called when this rule is processed.

  var parent = current.parent.getRefRecord();

  parent.u_version = current.u_version;// u will have to create custom field on parent table
   
  parent.update();


}

if this resolves your query do mark it correct n helpful
