Cannot Save empty cell, can only save 0

Hi all,

within IP Web layout, when I overwrite already filled input ready cell with 0, I can save that.

When I just delete the value (e.g. 500) of the cell and save, the 500 reappear.

Does anyone know if the query / Web layout can be configured in a way that it interprets empty cells as 0?

Thanks & Best Regards

Gernot
