account dim(design)

HI Friends,

I have multiple plng applications. which is best practice between below 2.

Using separate account dims for each application or using single dim for all applications.

Could anyone guide me based on volume comparison?

I have seen one case where all applicaitons are using single account dim, whose members are around 1500, but trying to add properties system taking so much of time, even not allowing to add properties. If it the case, can i use it account dim as owner dim in work status definition.

thanks.
