Hi all,

I have a problem I can't seem to solve on my own.

I have products in my database that each have 1 of 3 different taxtypes (TAX_A (high tax), TAX_B(low tax), TAX_C(no tax)) and 1 of 3 different producttypes (RENTAL, BUY, PACKAGING)

Now on my invoice I want the following TAXES to be displayed.

RENTAL (=products that are TAX_A and RENTAL)

BUY HIGH (=products that are TAX_A and BUY but not Items::IT_Type= "Drinks 19%" or Items::IT_Type= "Drinks 6%"))

BUY LOW (=products that are TAX_B and BUY but not Items::IT_Type= "Drinks 19%" or Items::IT_Type= "Drinks 6%")

DRINKS HIGH (=products that are TAX_A and Items::IT_Type= "Drinks 19%")

DRINKS LOW (=products that are TAX_B and Items::IT_Type= "Drinks 6%"))

PACKAGING (=products that are TAX_C and PACKAGING)

So I have to make a some sums but only from the prices of the products that have those 2 conditions...

I hope you guys know what I mean...

You may want to try CASE, this should do what you are looking for.

case(

producttype = "Rental" and taxtype = tax_a; formula1;

(producttype = "Buyl" and taxtype = tax_a) and not (Items::IT_Type = "Drinks 19%" or Items::IT_Type = "Drinks 6%" ; formula2;

etc....

)

Thanks for your reply.

Still can't figure out how to display the tax. I got this:

On the invoice I got a field:

<<Bestellingnummer naar BesteldJoin::FACT_BTW_HUUR>

In the database I got a field in the "orders" table called "FACT_BTW_HUUR" with:

Case(

Items::IT_KoopHuur = "HUUR" and Items::IT_BTWType ="A"; FACT_Bruto_BTWA)

It's dutch..."HUUR" is dutch for "RENTAL"

FACT_Bruto_BTWA has this function:

Sum(Besteld BestNr naar Orders::IT_metBTW_A) + FACT_Bezorgkosten + FACT_BreukTotaalInclBTW

Anyone able to help?

thanks
