How to not select an invoice if a certain line item type is present?

Question

Hi,
I've created a report that lists all invoices that have a particular line item type on it.  For example, I wanted to produce a revenue report by item type, "P-Tank". So, the invoice table links to the invoice line items table. Each line item record has a "resource id" on it. The resource id links to the resource type table. So, if invoice #8 has, say, three line items and one of them has a resource type of "P-Tank" then I report on it.  Basically, I'm making a report grouped by Resource ID and the Resource ID must by of Resource Type 1, 2 or 3.  So, this report I've solved.
Now, I want to report on those invoices that do not have either a resource type 1, 2 or 3 item on it.  If I use a formula:
"Not ({resource_type.resource_type_id} in [1, 2, 3]) that doesn't work because it just omits the line item that is of resource type 1, 2 or 3....but still leaves the invoice on the report with the other line item types. * I want to identify any and all invoices that do not have either a line item resource type 1, 2, or 3 on it.*
Any help is much appreciated!
thx,
Mark

Answer 1

Hi Abhilash,
That didn't seem towork.  I'll simplify the example to see if we can find the answer easier this way.
I'm using two tables: invoice; and invoice_items
An invoice can have many items on it.
I don't want my query to select any invoices that have a Tank item on it (Tank has a resource id = 8).
So, I'll join the invoice table to the invoice_items table:
invoice.invoice_id = invoice_items.invoice_id.
The result set looks like the following:
Invoice #        Invoice Item #     Invoice Resource ID
22                              1                               8
22                              2                               9
23                              1                               5
So, because Invoice #22 has a line item with resource id = 8 on it I do not want Invoice #22 to appear on the report at all, regardless of what other items and resource id's are on it.
I have tried joining the two tables in every manner (e.g. inner, outer, not enforced, enforced, etc) and even when I put the condition, invoice_items.resource_id <> 8, it still brings up Invoice #22 but just omits the one line item and leaves the record with resource id 9 (in the example above).  I don't want Invoice #22 to appear at all in the report.
Does that help clarify the problem?
