Increase rollup fields maximum
Recently we started transition from Dynamics CRM 2011 to 2015. As part of transition we started using rollup fields. There are some limitations for that feature:
You can define a maximum of 100 rollup fields for the organization and up to 10 rollup fields per entity.
Which we faced on our dev organization during solution import.
You can't add a rollup field. You’ve reached the maximum number of {0} allowed for this record type.
You can't add a rollup field. You’ve reached the maximum number of {0} allowed for your organization.
It wasn't hard to find that settings in DB and adjust them a bit:
Add-PSSnapin -Name Microsoft.Crm.Powershell
Set-CrmAdvancedSetting -ConfigurationEntityName Deployment -Setting MaxRollupFieldsPerEntity -Value 11
Set-CrmAdvancedSetting -ConfigurationEntityName Deployment -Setting MaxRollupFieldsPerOrg-Value 110
Note that this settings are in deployment scope and will affect all organizations. Also it may have impact performance.
