Question

I am using 4 ddic tables as follows:-
Building:-
                  Building_id  (primary key)
                  Name
                  Address
Property:-
                   Flat_id (primary Key)
                   Building_id (foreign key relation to building)
Booking:-
                  Flat_id (foreign key relation to property)
                  Cust_name
                  Cust_add
Payment:-
                 Pymnt_id (primary key)
                 Flat_id (foreign key relation to property)
                 Date
                 Amnt
                 Currency
I generate 3 reports as follows:-
1)      Total Property (displaying flat_id Building_id name address)
2)      No Of bookings (displaying flat_id building_id cust_name cust_add)
3)      How much payment.
1:    When i used SMARTFORMS in my reports problem is tht i for data i am using internal table of composit type means some fields from one table and another field from another, but in using smartforms i need to specify a internal table tht can only be like some DDIC structure.
Like in second report flat_id , cust_name, cust_add come from one table and building_id come from another table. Now how i can pass this table to smartforms so tht it can process this.
2: have a problem when i want to print currency field 'AMOUNT ' in smartforms which is a referenced field in ddic so  there was an error that 'reference field WA-AMOUNT is unknown in form'.
I am not be able to resolve these problems . Due to this i can not continue further.
please help me.

Answer 1

Hi,
You have to define a structure of same fields  which you require and refer that structure to you table in smartforms in both the driver program and smartforms interface
second you have to provide that field which is the currency and quantity in global definitions tab.
or.
declare a field of type p decimals 2 in global definitions and in the
program lines do this  provide the structure which contains the amount field as input field and output field as g_amount
  G_amount = wa-amount.
