Trying to use Concat to merge values in a string with constraint

I have a Sharepoint list called MeterReadings which has a field called auth. This field can contain one value like "9876AP6829" or many values like "9876AP6829; 9875AP6829; 9874AP6829"

I am trying to merge all the values together IF 1 value is present more than once within that subset - please see the example attached for what I am trying to achieve

My Gallery Items is:

GroupBy(
    SortByColumns(
        Filter(
            MeterReadings,
            readdate >= (DatePickerFrom_5.SelectedDate) && readdate <= DatePickerTo_5.SelectedDate && (StartsWith(
                auth,
                TextInput2.Text
            ) || StartsWith(
                clientname,
                TextInput2.Text
            ))
        ),
        "auth"
    ),
    auth,
    Data
)

A little more explanation could be useful; The MeterReadings table contains water meter readings for a client/s. A client is identified by an auth or a number of auths or a combination of auths separated by "; "

If, for example there is a MeterReading against auth 05629K AND there is another reading against 05629K; 624367; 624368; 624918 it's very likely that this is the same client and so we want to combine or merge all the auths that look like they are related and then calculate water usage based on ALL those meter readings. I hope I have explained this correctly - the spreadsheet attached has sample data and expected outcomes

I would like to put the Concat within/on the end of this if possible

thanking you :)

Are you just trying to display the items in that manner or modify the list?

How many records would you be accessing as there would be delegable issues?

@ronaldwalcott

I just want to modify the list so I can calculate usage based on the new auths value

I'm accessing 8000 records but I have created a collection on startup which gathers all records

Hi @bobgodin

I am rather confused as to how the right table is extracted from the left one (the logic behind this - where are the additional values being identified from ?)

OK @bobgodin

I see it now. I think you will appreciate the complexity of this from the code below - fried a few brain cells on the way . . .
I have no idea however how your device is going to handle this through an 8,000 records collection (and none of it is remotely Delegable)

ShowColumns( AddColumns( AddColumns( Table1, Base, If( ";" in auth, First( Split( auth, ";" ) ).Value, auth ) ), mergedauths, LookUp( AddColumns( GroupBy( Ungroup( AddColumns( AddColumns( Table1, Auths, Split( auth, ";" ).Value ), MainAuth, First(Auths).Value ), Auths ), MainAuth, Data ), AllAuths, Concat( Distinct( Data, Value ), Value, ";" ) ), MainAuth = Base ).AllAuths ), mergedauths, readdate, reading )

Hi @WarrenBelz thank you so much - that code has done the trick - just one more silly question:
How can I incorporate that into my Items property for my Gallery:

GroupBy( SortByColumns( Filter( colMRsbyWMA, readdate >= DatePickerFrom_3.SelectedDate && readdate <= DatePickerTo_3.SelectedDate && StartsWith( wma, Dropdown2_1.Selected.Result ) && (TextInput2.Text in auth || StartsWith( clientname, TextInput2.Text )) ), "auth" ), auth, Data )

and btw I am using a collection to start with and then creating a smaller collection when the user chooses a wma value from Dropdown and THAT'S where the Concat/Split etc is applied

Hi @bobgodin

You can get the filter in near the top as shown below, but the auth column no longer exists (you wanted mergedauths) as per the sample you posted and it is already grouped to achieve this added column.
ShowColumns( AddColumns( AddColumns( Filter( colMRsbyWMA, readdate >= DatePickerFrom_3.SelectedDate && readdate <= DatePickerTo_3.SelectedDate && StartsWith( wma, Dropdown2_1.Selected.Result ) && ( TextInput2.Text in auth || StartsWith( clientname, TextInput2.Text ) ) ), Base, If( ";" in auth, First( Split( auth, ";" ) ).Value, auth ) ), mergedauths, LookUp( AddColumns( GroupBy( Ungroup( AddColumns( AddColumns( colMRsbyWMA, Auths, Split( auth, ";" ).Value ), MainAuth, First(Auths).Value ), Auths ), MainAuth, Data ), AllAuths, Concat( Distinct( Data, Value ), Value, ";" ) ), MainAuth = Base ).AllAuths ), mergedauths, readdate, reading )
