increase cross-object reference

I'm getting following error when creating a formula field
"Error 'Maximum of 15 object references on Object Name. You must remove at least 1 relationships' when you create a formula"

Salesforce article says we can raise salesforce ticket to increase the limit to 20, if we raise the ticket do they increase the limit in production? if YES, how do we pull down the change to lower environments? Any ideas

Hi Naresh,

Yes, you can increase the limit,  However, while it is possible to extend the limit of the spanning relationship to 20 there are potential performance implications of doing so. More complex formulas (e.g. more spans) may result in increased response times evaluating formulas. For example, a page will be slower if it shows fields that have more spans.  Therefore, the information above is crucial in ensuring Spanning Relationships are used efficiently.

You can include lower environment Org Id's along with production so that limit can be increased as per your request.

Hope above information was helpful.
