To debug without setting up a startup project and startup object in D365 fotr operations. Follow these steps:
- Open your object in visual studio
- Place breakpoints
- Goto Debug>attach to process and check show processes from all users
- Select w3wp.exe and click attach.
You can execute your process now from the client and execution will be stopped at your breakpoints.
Recently faced a problem where my breakpoints weren’t loading for objects in the AOT that were not in my solution and therefore I could not debug.
Solution: In order to load symbols for objects that have not been included in your solution you have to uncheck the following check box.
Load symbols only for items in the solution

To recall a workflow through code you can use the cancelworkflow method in workflow class. It takes the correlationId and a comment as parameters and gets the job done for you. Example
workflow::cancelworkflow(CorrelationId, “Cancelling this workflow”)
Now you are probably thinking How do I find my workflows CorrelationId. You can do that by querying WorkflowTrackingStatusTable sorting it with time and instance number and joining it with SysWorkflowtable against the correlationId field and in the contextId you pass the RecId of your record for example PO RecId.
In X++ we have the below methods for fetching data after any changes are made, below is the short description of what they are and when to use each one.
Refresh() refreshes the user view with whats stored in the caches. This does not touch the DB.
Use this after any form change has been made through code.
ReRead() fetches only the current record from database and does not re read the complete datasource.
Use this when you need to update only the current record after modifying any value.
ReSearch() will execute the same query again and fetch the results from the database.
Use this if you need to get the current most data from database.
ExecuteQuery() will run the query again just like research does but it will also take any query changes into account.
Use this is you have modified the query on run-time and need the updated results according to the new query.
To connect to an external database with X++ you can use Open Database Connection (ODBC) protocol through the OdbcConnection class among other ways. This approaches requires you to setup us a Data Source Name(DSN) on your server machine with the required access. Below is the code sample for how you can achieve this.To read more about this visit MSDN.
// X++, Main method in a class.
static public void Main(Args _args)
str sql, criteria;
// Set the information on the ODBC.
loginProperty = new LoginProperty();
//Create a connection to external database.
odbcConnection = new OdbcConnection(loginProperty);
sql = "SELECT * FROM MYTABLE WHERE FIELD = "
+ " ORDER BY FIELD1, FIELD2 ASC ;";
//Assert permission for executing the sql string.
perm = new SqlStatementExecutePermission(sql);
//Prepare the sql statement.
statement = odbcConnection.createStatement();
resultSet = statement.executeQuery(sql);
//Cause the sql statement to run,
//then loop through each row in the result.
//It is not possible to get field 3 and then 1.
//Always get fields in numerical order, such as 1 then 2 the 3 etc.
//Close the connection.
error("Failed to log on to the database through ODBC.");
Here is how you can connect to an external database using X++ SqlClient class. This is among the few others approaches you can connect to an external database.
public System.Data.SqlClient.SqlConnection getConnection()
connectionString = “Persist Security Info=False;User ID=UserID;Pwd=Password;Initial Catalog=DatabaseName;Data Source=localhost;”;
connection = new System.Data.SqlClient.SqlConnection(connectionString);
error(“An exception has occurred.”);
error(“A CLR exception has occurred.”);
exception = CLRInterop::getLastException();
if (exception != null)
To run a query after a successful connection, use this code:
str sql, attributeName, attributeValue;
str 30 materialCode;
mzkConnectToDB = new MzkConnectToDB();
conn = mzkConnectToMSDgen.getConnection();
sql = strFmt(“select * from tablename;”);
cmd = new System.Data.SqlClient.SqlCommand(sql,conn);
dr = cmd.ExecuteReader();
materialCode = dr.get_Item(‘material_id’);
//Close the connection.
While creating a certificate with the MakeCert utility you might face this Error: Save encoded certificate to store failed => 0x5 (5) as I did, dont be worried its not about your command the solution to this is to simply start your command prompt or powershell as an administrator and then run the command; the certificate will be created successfully.
