Linking using formula column

I've tried several ways of doing this, and this seems to be the easiest way. Basically, depending on the type of record, I need to use one of two columns to link to another query. So, if a row in query A has type 1, I need to use column X to link to query B. If a row in query A has type 2, I need to use column Y to link to query B.
I thought the easiest way to do this would be to create a formula column in Query A that was the value of column X or Y as appropriate and then link to Query B using this formula field. However, I can't seem to link queries using a formula.
Does anyone have any ideas how I can accomplish this? I'm new with Oracle reports, so go easy on me :)
Thanks,
Julie.

What error are you getting?
Is it: REP-1297: Data link child column 'CF_1' must be a database column?
If so, the reason is the child column cannot be a formula column. The parent column, on the other hand, can be a formula column.
If I understand your data model correctly, "A" is your parent query/group and "CF_1" is the formula column in query/group "A".
"B" is your child query. "FK_1" (the foreign key column in query "B") is your child column.
You should be able to link "CF_1" in "A" to "FK_1" in "B" by doing:
- click on the link tool
- click on "CF_1" in "A"
- drag to "FK_1" in "B"
- A link should be created. Double click on it to bring up the property palette for that link and you'd see the link properties.
Hope that helps...

Not able to burst report referring to Formula Column in XML file.

Hello all,
I am using bursting feature to spit single report to multiple pdfs. All is well when I reference column queried from the database in the xml file but I when I give column from Formula column it is doing coredump.
XML File contents:
=====================
<destinations>

<foreach>
<file id="MyFiles" name="/data/reports/pdf/assrt_terr&<file_name>.pdf" format=
"pdf" instance="this">
<include src="report"/>
</file>
</foreach>
</destinations>
=====================
The "file_name" referenced in the above is a formula column. If it is replace with a column from the query it works fine. Please let me know if anyone knows if it is a limitation or any workaround?
Thanks in advance,
Manohar

If I can have that in the query I would have not done a formula column. And I do know that it works if the column is in the query. I would like to know any workaround to make it work from formula column.
I have to take data from sub-group of this query, aggregate it and then concatinate with one of the columns grouped - so i had to use formula column.
Thanks
Manohar

Formula Column in Hyperion Planning 11.1.2.1

Hi ,
I need to create a Formula Column in web form taking excel sheet as reference for creating the formula.
Excel sheet has formula = iferror((A/B),0,(A/B)), where A and B are columns.I need to create a column C and has to put this excel formula using formula column functionality.
Please let me know all possible solutions for replicating this excel formula in formula column,
Thanks.

Here's why this is a bit tricky. You would likely want to use a formula something like this:
IfThen(IsError(Eval([A]/[B])), 0, Eval([A]/[B]))
But here's the problem . . . you can't pass the IsError function a calculation, even when it's enclosed in the Eval function. At least I've never gotten this to work.
So what you have to do is create another column . . . call it column [F] for this example. In that column, place the formula [A]/[B]. Hide this column.
Then for your formula column, use the following formula:
IfThen(IsError([F]), 0, Eval([A]/[B]))
You could alternatively use this:
IfThen(IsError([F]), 0, [F])
The key is to use a hidden column to perform your calculation, and then evaluate whether that hidden column produces an error.
Hope this helps,

Bad Bind Varaibles in FORMULA COLUMN

end;
IT GIVES AN ERROR bad bind variables f_cashamt and f_creditcardamt.but these two are in layout editor..
pls help me as soon as possbile.
Thanx in advance..

Hello,
Try using the source of the field, rather than the name of the field. You can find the source in the layout editor. Click on the field and then press your F4 key. The properties of that field will come up. Find the source name and use the source name in your formula. Hope this helps.

hi Dipti,
there is no column which contains the ItemURL.
if you want a colum to have url than you need to create a workflow
which calculate the ItemUrl and store it in custom column
use the below article to do this

Using PL/SQL in a formula column in Oracle Reports Builder.

Hi,
I need to SUM two record from the result of an SQL interrogation.
Here's what it looks like
function CF_1Formula return Number is
nTot1 NUMBER :=0;
nTot2 NUMBER :=0;
begin
     select sum(:TOT1) into nTot1 from table(Q1) ;
     select sum(:TOT2) into nTot2 from table(Q1) ;
     return (nTot1 + nTot2);
end;I'm kind of new to formula column programming any link of interest would be appreciated.
The from table(Q1) part Q1 represents my SQL interrogation name and the group below it is G_MAIN.

Hi Hong Kong King Kong,
From looking at that function name (and the group name): Is this an Oracle Reports generated function?
If so, there's also a dedicated Reports forum: Reports
By the way, I like your synonym for 'query'.
I'm sure I'll confuse some of my collegues tomorrow when I will mention 'database interrogation' instead of 'query'. ;)

Doh...I should not underestimate the information that is posted in thread subjects.
