AB#2342

[Jenefer-Monroe]

Can you confirm, did this still repro after the successful envt dataflow refresh?

[Jenefer-Monroe]

OK strange ask but can you try this? I found that the Data Export file for Apps had started to include MDAs so I wonder if its because bad data was getting written in the Apps table for MDAs.

1. Open the PowerApps Apps table where you can delete rows and delete MDA rows without an App Unique Name. (Alternatively you could run the Check Deleted flows)

2. Open the CoE BYODL Apps Dataflow and put this in the Advanced Editor for Apps query

in
    #"Remove MDAs"

3. Publish that change
4. Rerun MDA dataflow

[nasilvae]

When we checked the PowerApps Apps table it did not had any MDAs. We did noticed however multiple entries of records that the App type column was empty.

The app dataflow is not able run yet, after applying the fix we get the same error.

[Jenefer-Monroe]

ok looks like the same error then. thats a bummer. ill see if Manuela has an idea for your issue.

[nasilvae]

ok looks like the same error then. thats a bummer. ill see if Manuela has an idea for your issue.

We noticed that there is over 5k records that do no have an app type nor an unique name (unique name is empty). We are performing a bulk delete on these records just in case.

[Jenefer-Monroe]

ok im making sure the way the export tracks app type hasnt changed in need on an update.

[Jenefer-Monroe]

ok the blank types were likely component libraries. also a change to the data export file. updated:
#7697

[nasilvae]

Hey so, I have this modified query for the apps dataflow. This helps with the validation of the null values in the admin_maker table that seems to be causing the issue. So far the query seems to be working.

Now we only have one dataflow that is not working which is the model driven one. I tried using the same query above and change the filters to "adapt it" to mda but i didnt work. Let me know your thoughts on the query We are using for apps and if this is something that we can use for model driven apps dataflow. I suspect the model driven one will be fixed by a similar approach since it was the same error the enumeration error.

[Jenefer-Monroe]

Sorry can you please tell me what change you made in the above? That way I can validate it works. I cant just take the whole blob unfortunately.

My MDA one is working.

[nasilvae]

Sorry can you please tell me what change you made in the above? That way I can validate it works. I cant just take the whole blob unfortunately.

My MDA one is working.

my mda is having the enumeration issue still. The apps one used to have the enumeration issue but added some logic when it tries to get the values from the admin_maker table. Im not at the pc now but once I get a moment i can get more specific.

[nasilvae]

These Queries are based on the Apps Dataflow under the apps table. It fixed the enumerator issue but not sure how to apply this type of fix on the model driven app dataflow yet.

Query 1 is the Modified version I shared
Query 2 is your version on this thread.

Here are the key differences:

Handling Null Values in "Replaced SYSTEM createdBy" and "Replaced SYSTEM modifiedBY":
In Query 1, the columns "ActualCreatedPrincipalId" and "ActualLastModifiedPrincipalId" are explicitly set to type text, and then null values are replaced using Table.ReplaceValue function.
In Query 2, the null values in the same columns are replaced directly using Table.ReplaceValue without explicitly setting the column types to text.

// Query 1
#"Replaced SYSTEM createdBy" = Table.AddColumn(#"Add Power Apps Type", "ActualCreatedPrincipalId", each if [createdPrincipalId] = null then Table.SelectRows(admin_makers, each [admin_displayname] = "SYSTEM"){0}[admin_makerid] else [createdPrincipalId], type text),
#"Replaced SYSTEM modifiedBY" = Table.AddColumn(#"Replaced SYSTEM createdBy", "ActualLastModifiedPrincipalId", each if [lastModifiedPrincipalId] = null then Table.SelectRows(admin_makers, each [admin_displayname] = "SYSTEM"){0}[admin_makerid] else [lastModifiedPrincipalId]),

// Query 2
#"Replaced SYSTEM createdBy" = Table.ReplaceValue(#"Add Power Apps Type", null, Table.SelectRows(admin_makers, each [admin_displayname] = "SYSTEM"){0}[admin_makerid], Replacer.ReplaceValue, {"createdPrincipalId"}),
#"Replaced SYSTEM modifiedBY" = Table.ReplaceValue(#"Replaced SYSTEM createdBy", null, Table.SelectRows(admin_makers, each [admin_displayname] = "SYSTEM"){0}[admin_makerid], Replacer.ReplaceValue, {"lastModifiedPrincipalId"}),
Handling Null Values in "Inserted conditional column 1":
In Query 1, the "markDeletedDate" column is set to null for rows where [markDeleted] is true. The type of the column is datetimezone.
In Query 2, the "markDeletedDate" column is set to null for rows where [markDeleted] is "Yes". The type of the column is datetimezone.

// Query 1
#"Inserted conditional column 1" = Table.AddColumn(#"Inserted conditional column", "markDeletedDate", each if [markDeleted] = true then [QueriedOn] else null),

// Query 2
#"Inserted conditional column 1" = Table.AddColumn(#"Inserted conditional column", "markDeletedDate", each if [markDeleted] = "Yes" then [QueriedOn] else null),

[Jenefer-Monroe]

the null type was due to a different issue, they changed how they marked up component libraries. So that part wont be needed.

[Jenefer-Monroe]

and I think the mark deleted is resolved by removing MDAs from the query. Can you please try this for the CoE BYODL Apps ddataflow apps query?

Hey Jenefer,

We get the following error at the following step:

Expression.Error: There weren't enough elements in the enumeration to complete the operation.
Details
Reason = Expression.Error
Detail = #table({"admin_jobtitle", "admin_displayname", "admin_userprincipalname", "admin_stateorprovince", "admin_makerid", "admin_useremail", "admin_accountenabled", "admin_recordguidasstring", "admin_userisserviceprinciple", "admin_office", "admin_preferredlanguage", "admin_department", "admin_city", "admin_company", "admin_country", "admin_makerisorphaned"}, {})

When we try the modified script it works but this one doesnt. I believe this error is because of the null values from the maker table which isnt complete because the cloud flow hasnt finished running. The modified query accounts for this issue.

Hey Jenefer,

We made a copy of the apps dataflow modified query and changed the exclude mda filter condition to now exclude everything except mdas. We then used the dataflow id of that new dataflow and replaced the mda dataflow id environment variable so its part of the refresh workflow.

We now have mda apps inventoried. All dataflows are working except for the original mda. Our Maker cloud flow is still running (1.5 days running) account is not used in any other solutions. We noticed that we have multiple apps that do not have the owner information in our reports but we suspect its because of the maker byodl cloudflow not complete.

Chatted offline. Appears this is really about the on-complete flow for the Maker dataflow is running forever and so we dont get the needed makers here.
Put this filter
(admin_makerisorphaned eq true or admin_displayname eq 'Unknown') and createdon gt '@{formatDateTime(addDays(utcNow(), -1), 'yyyy-MM-dd')}'

Here

Happy to report CoE is running on our side

We still suspect that there might be some incomplete data given all of the extra customizations that we did on our side but we are hoping the cleanup flows cleans it up. Next week we will try to run the dataflows with the regular scripts. Will let you know if anything changes. Thank you again.

We noticed that the data is not being cleaned up. #7740
