Tabel1: ReportID(PK), OrderID (one report only has one order)
Tabel2: OrderID, ItemID (no primary key)
Tabel3: ItemID(PK), Itemname  

I need a formula to print all the itemnames for a certain ReportID in one field, so this field can appear in report heading. Can anyone please help? Thanks.

So is your report only reporting on one selected ReportID?

Assuming you are only reporting one ReportID in a report.

Create a formula fDetail:

global stringvar vItemnames;
vItemnames := vItemnames & ", " & {ItemId.ItemName};

This goes into the detail line but can be suppressed.

Create a formuls fRH:

Whileprintingrecords;
global stringvar vItemnames;
vItemnames

This goes into the report header and needs to be formatted as 'Can Grow'.

Yes, one selected ReportID.
I tried your suggestion, and get duplicated itemnames, and my other report details become duplicated as well.
 
Forgot to say, my report has two group sections. I have another two tables to hold printed details.
Table 4: Group1_name(PK), ReportID
Table 5: Group2_name, Group1_name - no PK in this table

Any more hints you can give me? Thanks

'get duplicated itemnames, and my other report details become duplicated as well

I can sort out the duplicated itemnames but I don't know what you mean by 'other report details'.
Nothing I am doing is affecting the rest of the report.

The formula to go into the detail line is:

global stringvar array itemnames1;
global numbervar x;
numbervar y;
numbervar z;
z:=0;
for y:=1 to x do
(
if itemnames1[y] = {ItemId.ItemName} then
(
z:=1
)
else
// do nothing
(
y:=y
);
);

if z=0 then
(x:=x+1;
redim preserve itemnames1[x];
itemnames1[x]:= {ItemId.ItemName};
0
)
else
(
x:=x;
0
);



The formula to go into the Report Header is :
whileprintingrecords;
global stringvar array itemnames1;
global numbervar x;
local stringvar result;
local numbervar xx;

result:= itemnames1[1];
for xx:=2 to x do
result:= result & chr(13) & itemnames1[xx];

result
