I am setting up a DirectQuery connection from my local MongoDB environment to Microsoft Power BI. I created a custom connector using the sample ODBC connector from Microsoft (https://github.com/microsoft/DataConnectors/tree/master/samples). I am using the latest MongoDB ODBC Driver and MongoDB ODBC Driver for BI Connector. I created a System Data Source that is used as the input for my custom connector.

I am bringing in the following collection to Power BI for DirectQuery:
tbllinktrafficdata. I try to create a Slicer with the LastUpdate field. When I filter on one LinkID (which is a field), I get the following error.

"ErrorMessage":"Failed to convert type bigint to integer, expression `LinkID` to 1506780."

"ErrorMessage":"This ODBC driver doesn't support SQL_FN_CVT_CONVERT or SQL_FN_CVT_CAST. You can override this by using SqlGetInfo for SQL_CONVERT_FUNCTIONS."

It looks like I'm seeing a conversion error, but I'm not sure how to resolve the issue within the connector code.

Here is my SqlGetInfo function:

SQLGetInfo = [
// place custom overrides here
SQL_SQL92_PREDICATES = ODBC[SQL_SP][All],
SQL_AGGREGATE_FUNCTIONS = ODBC[SQL_AF][All],
SQL_CONVERT_FUNCTIONS = ODBC[SQL_CVT][BIGINT]
],

//this is from OdbcConstants file that is called in Power Query file
SQL_CVT = [
BIGINT = 0x00004000
]

Here is more of the Power BI Trace Log:

Hi Everyone,

I am working on a automated deployment system that deploys  PowerBI reports to a new workspace. This is all working fine but the issue i am having is updating the datasource with a new URL to get their information from. These are all SharePoint List data sources that need to be updated.

I am using the Invoke-PowerBIRestMethod  to sucessfull get the data sources within a report and I can manipulate the return to change the URL but when sending the update back i just get an error.

No information is given with the error it just doesn't work.

Does anyone have a working example of updatiung a datasource with powershell?

I have seen this thread but it doesn't have a solution 

https://community.powerbi.com/t5/Developer/Power-BI-REST-API-via-Powershell-Create-Datasource/td-p/511934

using (var client = new PowerBIClient(new Uri(API_URL), new TokenCredentials(accessToken, "Bearer")))
{
Report powerBiReport = await client.Reports.GetReportInGroupAsync(groupId, reportId.ToString());
#region default
var generateTokenRequestParameters = new GenerateTokenRequest("view", null, identities: new List<EffectiveIdentity> { new EffectiveIdentity(username: username, roles: roles, datasets: new List<string> { powerBiReport.DatasetId }) });
var token = await client.Reports.GenerateTokenInGroupAsync(groupId, reportId, generateTokenRequestParameters);

}

it works fine without effectiveidentity ut it fails with effective identity. Please help in identifying the parameters

Hi  ,

Could you please make sure that your data source doesn't have any of the points listed in the restriction ?

  there are no restricitions.

Same issue here.  Shows on all of our client facing reports.  Please fix!

I was able to work around this by transforming in SqlColumn function. Odbc SQL types taken from ODBC constants SQL_TYPE (included below)

SQLColumns = (catalogName, schemaName, tableName, columnName, source) =>
let
OdbcSqlType.BIG_INT = -5,
OdbcSqlType.INTEGER = 4,

FixDataType = (dataType) =>
if dataType = OdbcSqlType.BIG_INT then
OdbcSqlType.INTEGER
else
dataType,
Transform = Table.TransformColumns(source, { { "DATA_TYPE", FixDataType } })
in
// the if statement conditions will force the values to evaluated/written to diagnostics
if (Diagnostics.LogValue("SQLColumns.TableName", tableName) <> "***" and Diagnostics.LogValue("SQLColumns.ColumnName", columnName) <> "***") then
let
// Outputting the entire table might be too large, and result in the value being truncated.
// We can output a row at a time instead with Table.TransformRows()
rows = Table.TransformRows(Transform, each Diagnostics.LogValue("SQLColumns", _)),
toTable = Table.FromRecords(rows)
in
Value.ReplaceType(toTable, Value.Type(Transform))
else
Transform,

Hello,

Im using an api to trigger a refresh on my dataset, and have been following instructions. Im pretty sure I have set it up correctly but for some reason I get a 404 error on Flow when testing. 

My dataset ID presents slightly different to the example but Ive tried to ensure im using the correct one. Any thoughts of what I could be doing incorrectly.

ID 

thanks

We are running into the same issue on our end. We have external users in the web application and we want to migrate them off of that into an embedded ISV solution, but we can't afford to lose the export to pdf option that the web service offers. Any ideas or thoughts about this issue would be greatly appreciated. 

Hello I'm back again within a few hours of my last question. I am trying to create a custom Power BI connector to set up a DirectQuery connection from my local MongoDB environment to Microsoft Power BI. I created a custom connector using the sample ODBC connector from Microsoft (https://github.com/microsoft/DataConnectors/tree/master/samples). I am using the latest MongoDB ODBC Driver and MongoDB ODBC Driver for BI Connector. I created a System Data Source that is used as the input for my custom connector.

I am bringing in the following collection to Power BI for DirectQuery: tbllinktrafficdata. I try to create a Slicer with the LastUpdate (timestamp) field. When I filter on one LinkID (which is a field), I get the following error.

"ErrorMessage":"Data Type of column LinkID with searchable property UNSEARCHABLE should be SEARCHABLE or ALL_EXCEPT_LIKE. You can override the supported data types from ODBC driver using SQLGetTypeInfo."

I tried changing the SEARCHABLE column in the SqlGetTypeInfo function as instructed in the trace logs, but it does not to seem to work. Here is my function call in the connector code. OdbcSearchable is set to 3 which is pulled from the OdbcConstants.pqm file

        SQLGetTypeInfo = (types) => 
            let
                OdbcSearchable = ODBC[SQL_SEARCHABLE][SEARCHABLE],
                OdbcAllExceptLike = ODBC[SQL_SEARCHABLE][ALL_EXCEPT_LIKE],
                SetSearchable = (dataType) =>
                        OdbcSearchable, // SQL_SEARCHABLE = 3
                        //OdbcAllExceptLike, // SQL_ALL_EXCEPT_LIKE = 2
                // Outputting the entire table might be too large, and result in the value being truncated.
                // We can output a row at a time instead with Table.TransformRows()
                //rows = Table.TransformRows(types, each Diagnostics.LogValue("SQLGetTypeInfo " & _[TYPE_NAME], _)),
                //toTable = Table.FromRecords(rows),

                //Update SEARCHABLE column to SQL_SEARCHABLE
                Transform = Table.TransformColumns(types, { { "SEARCHABLE", SetSearchable } })
            in
                Transform,

We are experiencing the same issue with the embedded reports.  Please fix asap.

I have a table with data like this:

Period     Col1      Col2

201908         5         10

201908         3         12

201908         4           9

201907         8         10

201907         7         13

I want a bar chart that shows Period as the legend.  The first column would be the sum of Col1 for 201908 (5+3+4) divided by the sum of Col2 (10+12+9).  The second column would be the sum of Col 1 for 201907 (8+10) divided by the sum of Col2 for 201907 (7 +13).  If I calculate the percentages by row, it does not return the correct amounts for the graph because it tries to summarize the percentages.  I do not want an average of the percentages.  I am able to get the correct amounts in a table, but I cannot figure out how to translate that into a bar chart.  Please help.

Answer from Power BI Support:

Once the latest version is updated customer need to manually update that from App source

no one got same issue with me? about blank string with combo box

Hi  ,

If you are using API, means make sure you are passing the correct Group ID (Workspace) there are 2 different api is there calling the dataset in MyWorkspace and with OtherWorkspace

Make sure you the credentials passing through the flow is able to see the dataset

Hi  ,

Try to find the error using Resolve-PowerBIError cmdlet or fiddler to capture the API error directly.

Just giving as the reference, to my artilce where you can find the some informations on the powershell scripts

Hi  ,

What do you mean by fails , do you get any error ? pls share that.

• Make sure that username,roles are not having null values
• Make sure your reports developed using the RLS

                    if (datasets.IsEffectiveIdentityRolesRequired == true)
                    {
                        if (!string.IsNullOrWhiteSpace(username))
                        {
                            var rls = new EffectiveIdentity { Username = username, Roles = new List<string> { roles }, Datasets = new List<string> { report.DatasetId } };

                            if (!string.IsNullOrWhiteSpace(roles))
                            {
                                var rolesList = new List<string>();
                                rolesList.AddRange(roles.Split(','));
                                rls.Roles = rolesList;
                            }
                            // Generate Embed Token with effective identities.
                            generateTokenRequestParameters = new GenerateTokenRequest(accessLevel: "view", identities: new List<EffectiveIdentity> { rls });
                        }
                    }

Try the above code which having more condition for you to check

Hello,

I'm creating a custom visual and I'm new to the creation process as well as learning Typescript/Javascript. I'd like to create a visual that can change the border color/style of a bar or change the shading style of a bar. What would be a good approach to begin creating this visual?

For further explanation, I have data laid like this:

Project       DateType      Date

A                 Actual1        1/1/2019

A                Planned1      2/1/2019

A                 Actual2        3/1/2019

A                Planned2      4/1/2019

B                  Actual1        5/1/2019

B                Planned1       6/1/2019

B                 Actual2         7/1/2019

B                Planned2       8/1/2019

I'd like to show the data either like this (changing border colors):

Or like this (changing the shading style):

Thanks for any help!
