Excel365 Cascading Data Validation between multiple worksheets (within same workbook) - no VBA

[Dimitri_TE]

I'm developing a workbook for Risk Analysis. Currently we have a single list/array with several thousand lines.
We want to make it more managable, by splitting it according the different departments.
But the Risk Theme and specific Risks are identical for all departments.

I've created a 'Background' sheet where there's a Table with the Risk Themes and the specific Risks that are linked.
The specific Risks are a casade of the Risk Theme: e.g.: High Risk jobs (= theme) has 4 specific risks, Chemical reagents (=theme) has 10 specific risks, etc
So far so good, when I create a cascading List on the Background sheet. When I select a Theme (purple cell I1 = dropdown box = based on unique List from column C), I get the Range in columns E and F. Based on selected value in I1 and with Data Validation, I'm able to fill the Dropdown box in I2 with the data from column F.


But now I want to make the formula dynamic by referencing the Theme from a any worksheet. So referencing in e.g. LabQC-Sheet must deliver the same cascading effect, but the Dropdown boxes will be located on the LaboQC-sheet, while the arrays are still on the Background-sheet. Extra attention is that the Dropdown boxes will be located in Named Tables.
Basicly: the reference to "I1" in the formula in the screenshot above, needs to be a Named Table reference of column D, on a worksheet that is not the Background worksheet.
