I have such columns in the report:
As well, I have a filter Type that can has three values: Customer, Supplier, ALL.
When I choose 'ALL' - I would like to see all 4 columns.
When I choose 'Customer' - I would like to see only 2 columns - CustomerCode, CustomerName
When I choose 'Supplier' - I would like to see only 2 columns - SupplierCode,SupplierName.
I change expression for each column in Hidden tab, but I still have seen an error.
Could you please help me?
