Hi PowerApps Community,
I have searched for a solution for my query on here but to no avail..
I have two sharepoint lists. One to store the data from my app and a second to act as a look up table.
Ive created a new form and combo box where i have used the 'depends on' function.


Filter('CI Parent List', Title = DataCardValue19.Selected.Value)
The 'Title' column is the same as the parent control and I want it to filter 'Department' options.
However when i try to input a new form, all items except 'Department' pull through in the sharepoint list. A delegation warning appears saying 'The "Search" part of this formula might not work correctly on large data sets.'
Both lists combined contain no more than 250 rows, I have extended the row limit to 2000.
Any help with this issue would be greatly appreciated.
Thanks
