=palo.setdata(#NV;Falsch;....)

Hi akunz,

Are you loading 0's to your db? If not, are you sure they are 0 values? See this post:

RE: saving space : replace 0 with Null

hi there, thank's for the link

actually i'm still not happy, following exampel:

We have the value 500.0 at a cube-cell. This consume memory. Now we want to change this value to 0.0
We change the value with an excelformula palo.data( ..) and enter "0" or palo.setdata(0,...), and the question is if palo writes back 0 (this still consume memory) or palo writes back automaticly Null=NoValue (no memory consumption)

To do this in Alea it works with dbset(NV(),...) , is there something simular in palo?

Maybe this helps:

Delete partly data of a cube

I read it like there is no memory consumed by "saving" 0.
