Find? If? True and False for finding Data.

Hey everyone,

back again with a stumper! I can't figure

 

Here is my code:

If(
    IsBlank(
        Find(
            Concatenate(
                First(col_currentview).TMMID,
                ";",
                First(col_currentview).TMName,
                ";",
                First(col_currentview).TMShift,
                ";",
                "NotTrained"
            ),
            ThisItem.Sign_data_A
        )
    ),
    "Not Trained",
    "Trained"
)

 

Here is the exampled string from my sharepoint list I am searching in:

@KRider 

Couple of things with that (and this is not related to the final solution...this is just issues with your formulas).

1) You are referencing the SelectedText property of your dropdown controls.  That is a deprecated property and should be replaced with the appropriate Selected.<columnName> instead.

 

2) Your left gallery items is working from two different lists.  This is usually a bad thing in an items property of any control, to have different sources used.  The only "saving" factor in this is that you are putting them all through Distinct, which will reduce them to the same schema.  But, it is still a red flag.

 

3) Given the point 1 above, you can refactor your formulas to be a little more maintainable and easier to read.

Items property for the right Gallery:

Distinct(
    Filter(command_process_certification,
        (dpdn_tmp.Selected.Value = "Team Member" && TMName = gly_tm_proc.Selected.Result) ||
        (dpdn_tmp.Selected.Value = "Process" && dpdn_shift.Selected.Value = "All" && TMProcess = gly_tm_proc.Selected.Result) ||
        (dpdn_tmp.Selected.Value = "Process" && TMProcess = gly_tm_proc.Selected.Result && TMShift = dpdn_shift.Selected.Value)
    ),
    If(dpdn_tmp.Selected.Value = "Team Member", TMProcess, TMName) & "; " & Title
)

 

Items property for the left Gallery:

Switch(dpdn_tmp.Selected.Value, 
    "Team Member",
        Distinct(
            Filter(command_employee_list,
	        (dpdn_shift.Selected.Value = "All" || TMShift = dpdn_shift.Selected.Value),
	        (&& dpdn_line.Selected.Result = "All Lines" || TMLine = dpdn_line.Selected.Result)
            ),
            TMName
        
        ),
    "Process"
        Distinct(
            Filter(command_WA_processes,
                (dpdn_line.Selected.Result = "All Lines" || Title = dpdn_line.Selected.Result)
            ),
            'Process Name'
        )
)

It appears that the left gallery is informational only as nothing so far that I see refers to it.

 

Your OnSelect for the right gallery can be the following:

Set(glbCurrentRecord, LookUp(command_process_certification, Title = Trim(Index(Split(ThisItem.Result, ";"), 2).Result))));

Set(varCert, "View");   // not sure of the use
Set(varsignoff, "Off");  // not sure of the use

Navigate(proc_view,ScreenTransition.Cover)

Not sure what the other variables are for, but left alone for now.

The glbCurrentRecord now becomes your primary record from the selection.  It can be referenced elsewhere.

 

Now, your Items property for the DCR gallery would become:

Sort(
    Filter(command_DCR_database,
        'DCR Name' = glbCurrentRecord.TMProcess
    ),
    'DCR Number', Descending
)

 

NOW...finally, the Label for Trained and Not Trained would be:

With(glbCurrentRecord,
    If(
        !($"{TMMID};{TMName};{TMSHIFT};Trained" in ThisItem.Sign_data_A), "Not "
    ) & "Trained"
)

 

Sorry it took so many questions...needed to review several times just to make sure I was picking up what you were putting down.

 

Let me know where you run into issues on the above (keeping in mind this is all hand-typed, so no error checking is available).

Good day sir! It's saying This formula uses scope, which is not presently supported. If I change the code below to "DCR0009295" - The item I am testing with. Then the code works. I am doing this in a gallery.

 

I modified the code to this:

"Trained: " & 
If(
    Concatenate(
        First(col_currentview).TMMID,
        ";",
        First(col_currentview).TMName,
        ";",
        First(col_currentview).TMShift,
        ";",
        "NotTrained"
    ) in 
    LookUp(
        command_DCR_database,
        'DCR Number' = ThisItem.Sign_data_A,
        Sign_data_A
    ),
    "Not Trained",
    "Trained"
)

"This formula uses scope, which is not presently supported." is not an error!!  It is a notice that the formula editor cannot determine which "ThisItem" it should apply the in-line value representation to show.  This is completely normal on a formula that refers to any derived records (from the Items property).

 

But the question is - beside the notification message - what trouble/error are you having?

I'm doing this in the gallery itself, how do I pin point the gallery item I am trying to find the string in? Right now all items in the gallery say trained:

When a DCR is made, it collects the people that know the job and stores them in this column. This is the code for collecting that data:

If(
    IsBlank(ThisItem.Sign_data_A),
    ClearCollect(
        col_current_dcr,
        Filter(
            command_process_certification,
            TMProcess = var_Selected_P
        )
    );
    RemoveIf(
        col_current_dcr,
        Not(TMLine in LookUp(command_employee_list,Title = TMMID,TMLine))
    );
    Set(var_DCR_String, Concat(col_current_dcr,ThisRecord.TMMID & ";" & ThisRecord.TMName & ";" & ThisRecord.TMShift & ";" & "NotTrained" & ";" & Today() & ";"));
    Patch(
        command_DCR_database,
        ThisItem,
        {
            Sign_data_A: Concat(col_current_dcr,ThisRecord.TMMID & ";" & ThisRecord.TMName & ";" & ThisRecord.TMShift & ";" & "NotTrained" & ";" & Today() & ";")
        }
    );
    ClearCollect(
        col_dcrString,
        With({
            _items: Split(var_DCR_String,";")},
            ForAll(
                Sequence(
                    CountRows(_items) / 5, 1, 5
                ),
                {
                MTID: Last(FirstN(_items,Value)).Result,
                TMName: Last(FirstN(_items,Value + 1)).Result,
                Shift: Last(FirstN(_items,Value + 2)).Result,
                Trained: Last(FirstN(_items,Value + 3)).Result,
                Date: Last(FirstN(_items,Value + 4)).Result
                }
            )
        )
    ),
    ClearCollect(
        col_dcrString,
        With({
            _items: Split(ThisItem.Sign_data_A,";")},
            ForAll(

                    CountRows(_items) / 5, 1, 5
                ),
                {

I see!  Lots of collections used that aren't needed, but that is not so much the issue in what you have for your gallery at this point.

 

What I am gathering from that is that the Sign_data_A column contains the text string that I mentioned??  Is that in each record of your gallery?

 

I guess I am still not understanding (in relation to each row/record in your gallery), where is that text string coming from?  Is it in the record of the gallery, or is it in some other record in some other list, or has it been pulled into some other variable already?

Sorry, that string is ThisItem.Sign_data_A I went to collections to avoid delegation errors? I am always trying to make my code more efficient. I also maybe use too many variables but maybe that's a talk for another time? hahaha.

 

The gallery items are:

Sort(
    Filter(
        command_DCR_database,
        'DCR Name' = var_DCR_view
    ),
    'DCR Number',
    Descending
)

 

The concatenate string I build is from the collection. I collect the TM's process certification and display it above the gallery:

KRider_0-1663261264581.png

 

Users select the Process Cert they want to see:

KRider_1-1663261332594.png

When they select a cert this is the code:

Set(varSelectedCert, Trim(Last(FirstN(Split(ThisItem.Result, ";"),2)).Result));
Set(varCert, "View");
ClearCollect(
    col_currentview,
    Filter(
        command_process_certification,
        Title = varSelectedCert
    )
);
Set(varsignoff, "Off");
Set(var_DCR_view, First(col_currentview).TMProcess);
Navigate(proc_view,ScreenTransition.Cover)

@KRider 

Yes...too many variables is too much like development.  PowerApps is not a development platform.  It is built on the concepts of Excel.  So, everything is referential and by formula evaluation.  PowerApps adds some abilities to make that concept more powerful, but they are to augment the concept, not to be the basis of the platform.  In other words...use variables very sparingly and only when really needed.  Refer to other places and data that you have already determined. 

As an example, you have a Set(var_DCR_view, First(col_currentview).TMProcess); statement in your formula.  This is redundant because First(col_currentview).TMProcess will have the value you want always.  var_DCR_view will only have a snapshot of it.

Collections are ONLY needed when you need an in-memory database in which you are planning to have the ability to add/remove/edit records in a table.  Otherwise, just use a table!!  Delegation is never avoided with collections.  Delegation and record limits are two entirely different things.  Your app should only ever work with the data that it needs...not all data.  This kills performance and is a waste of resources.

 

Okay...that said.

 

I still have one mystery to discover from you!

You reference First(col_currentview) in your original formula for the TMMID, TMName, and TMShift columns.

Why are you referencing a collection for this?  Wouldn't you want your data in that formula to come from your gallery row?  How does the collection play a part in that, and why?

 

Or I guess the question is more of - why does the First record of that table reflect what you want and not each row of it?  Your table is generated from a Filter...so there is only going to be records from the source table (what is command_process_certification by the way??)  So, why does the first record have some rank over the others?
