Hi ibox,

Thank you for your quick reply.

I've tried doing what you've suggested but it didn't work. The way that the dropdown is setup might be incorrect as I've got it to write into a LocalVariable called "SearchBy" and from what I understand it only writes the name of the attribute, e.g. "Courier", and not the full location reference, so what I tried doing is adding the "SearchBy" var to the location designation in different ways, like shown below, but I'm struggling to figure out how to do it

Below is an example of what happens when I use your method

Hi Mithun,
Thank you for your help, it solves part of the problem but I still can't figure out how to get the attribute that you search in to change dynamically, based on the input in the dropdown menu.
EDIT: I've tried your method of searching through multiple attributes and if I don't find a way to search through a selected attribute I will use that method, thank you.

Considering your scenario. I have made changes. I have added a static entity to get column names in the drop-down. Now based on a selection from the drop-down and the search key word, the result is getting fetched. 
Please find attached oml file.
If you don't want to add static entity, then create a one server action and pass the selected drop-down value's id, based on that gets the name and return it. Use the same name in the filter instead of --> SearchBy variable

Hi Mithun,

That does exactly what I wanted. thank you.

I've tried doing this with nested if statements but I think I've used the wrong syntax. 
Also, I see that, even if set up the function correctly, It wouldn't work with how I have set up the dropdown (which I suspected before) so thank you for showing me the correct way to achieve this.

Hi Marcin,

I am glad that I could able to help you.

Happy learning 

Hi Mithun,
Do you know why the Courier input box pre-fills with "COUNTER" in this new version?
I don't see where the default value might coming from.

Hi Marchin, Are you talking about pre-filled form. Please refer below screen shot

if yes, Because input box values is getting hold by the aggregate attribute e.g DispatchTrackingDatabase.List.Current.DispatchTracking.Courier. Hence we are getting pre-filled values.

Hi Mithun,

I'm talking about the two fields shown in the screenshot.

When the form is refreshed, the "Courier" field contains "COUNTER" and the "Stock" field contains "0"

It's not a huge deal but ideally, I would like all the fields to be empty.
Seems like something is setting these values after the "SaveOnClick" logic is completed as there is a "RefreshData" logic module that I'm using to reset the form after a successful submission.

Hi Luis,
As Mithun mentioned, the way the dropdown was set up originally wouldn't work as it was only writing the names of the attributes, which I then tried appending within the function.

You both have pointed out that the dropdown needs to grab the Id and Label instead, which I will try to remember for the future.
I'm sure your function would achieve the same result but I've already tested Mithuns implementation and it works so I will stick with that.

Thank you for your help.
