I know 'Some to All' is not the best allocation strategy and it can have performance implications, but we have a need to spread some direct service costs to all business units.  The total row count is 15.  Does anyone think that would pose a big problem?  I know we won't know for sure until we do a project copy, but figured I'd see what others thought first while I'm still testing.  Thanks in advance!

Assuming the business unit object is the one with 15 rows, how many rows do you have in your services object? Unless you have thousands of rows there, I would not expect it to have a large impact on your project calculation time.

Sweet, 170   Thanks, Meghan!!

Circling back because new situation  You mentioned thousands - is there a cap I should stay under - say 10k maybe or less?
