Q:

Include rollup field in other rollup calculation

I have three entities. There is 1:N relationship between entity1 and entity2. There is also 1:N relationship between entity2 and entity3.
Entity2 has subgrid representing entity3 records, and total field that calculates entity3 price field values. This works fine.
There is also subgrid on entity1 representing entity2 records and it includes total rollup filed. When i try to make new sum field that should be rollup and calculate sum of of all total field, there is not and option in rollup settings to add that field.
Is it possible to include rollup fileds in other rollup calculation, or I might have some other problem?

A:

Milos,
You cannot use nested rollup fields. Detailed information you can fine in this article - https://technet.microsoft.com/en-us/library/dn832162.aspx in paragraph Rollup Fields Considerations:

Rollup field considerations
You should be aware of certain conditions and restrictions when working with rollup fields:

You can define a maximum of 100 rollup fields for the organization and up to 10 rollup fields per entity.
A workflow can’t be triggered by the rollup field updates.
A workflow wait condition cannot use a rollup field.
A rollup over the rollup field is not supported.
