How to create entity relationship diagram (ERD) in AX 2012

Recently I have to generate a ER-diagram for specific list of tables in Dynamics Ax.  Dynamics Ax has built in feature.
Prerequisite of this article has Microsoft Visio.

Create a project for all tables which require in ER-diagram.
For this article I  created a new project with Name customer Address and drop CustTable and DirpartyTable in it.
Customer
In AOT or development workspace. Click on tools and reverse engineer menu .

4-1-2015 12-11-00 AM

Following form will open, Select location where file with ERX will be generated. Select your private or public projects.
4-1-2015 12-12-013
Click ok to generate it.

When file is generated, go on windows start up menu and open MS visio. Select database modeling Diagram Template.
4-1-2015 12-14-013

When Database Model diagram is open, From database menu=> Import=> Import Erwin ERX file…
load erx file generated in previous step. This menu is only available when you select Database diagram as template in Visio.
4-1-2015 12-15-44 AM
click on Browse.. button and load erx file.4-1-2015 12-17-52 AM


Click ok
A small dialog shows the import status
4-1-2015 12-18-19 AM
Next step you have to enable view for Tables, So you can select tables for ER-Diagram
Database=>View=> Tables and views
4-1-2015 12-18-57 AM
You will found following pane at left side of screen.
4-1-2015 12-19-20 AM
Click on required table to add it on page and it will show required tables with relationship.
4-1-2015 12-22-046


You can re-size these diagrams.

How to connect or access external database from AX 2012

Sometimes we have to communicate with outside of Dynamics Ax with in boundaries of Dynamics ax.
Consider following scenario where I have to communicate with StudentDb in Sql server and insert rows in Student Info. We can do this with odbc connection.


Now create New AX job and paste following code there


LoginProperty loginProperty;

OdbcConnection odbcConnection;

Statement statement;

ResultSet resultSet;

LoginProperty myLoginProperty;

str sql, criteria;

int output;

SqlStatementExecutePermission perm;

str myUserName="dynamicworld\\aliraza.zaidi";

str myPassword="abcd";

str myConnectionString;

 

;

 

 

 

 

myConnectionString=strfmt("UID=%1;PWD=%2",myUserName,myPassword);

myLoginProperty = new LoginProperty();

myLoginProperty.setServer("WIN-IKPOSIU2SGD");

myLoginProperty.setDatabase("studentdb");

myLoginProperty.setOther(myConnectionString);

 

//Create a connection to external database.

odbcConnection = new OdbcConnection(myLoginProperty);

 

if (odbcConnection)

{

 

sql ="INSERT INTO ..[StudentInfo]([FirstName],[LastName]) VALUES ('aliraza','zaidi')";

//Assert permission for executing the sql string.

perm = new SqlStatementExecutePermission(sql);

perm.assert();

 

//Prepare the sql statement.

statement = odbcConnection.createStatement();

output = statement.executeUpdate(sql);

 

 

statement.close();

}

else

{

error("Failed to log on to the database through ODBC.");
}

How to clear the cache of all clients in AX 2012

According to that reference we have to reset the GUID, so all Clients have to reset its cache, this method required AOS restart.
static void ResetAUC(Args _args)
{
#AiF
SysSQMSettings _Settings;
;
ttsbegin;
update_recordset _Settings setting GlobalGUID = str2Guid(#EmptyGuidString);
ttscommit;
info("Now we have to Restart the AOS Service to use a new GlobalGUID.");
}

Its works for me.

List of functions in SSRS reports in AX 2012

During working in SSRS reports I have to handle division by Zero error for calculating accumulated cost by dividing Amount by Quantity.

This expression works for me.

IIf(Sum(Fields!xyz.Value) = 0, “N/A”, Sum(Fields!abc.Value) / IIf(Sum(Fields!abc.Value) = 0, 1,Sum(Fields!xvz.Value)))
I did little research on Expressions and function used in these SSRS expressions


Expressions:
Expressions are used for manipulate or update the value, for example, cost show by dividing amount by Quantity. Rounding of decimal. Similarly Expression can be used to highlight the filed if condition meets. Style font can be changed, even you can uses switch statement, to change the display value of report.

Types of Expressions
Globals
Operators – Arithmetic, Comparison, Logical
Common Functions – Text, Date & Time, Math, Inspection, Program Flow, Aggregate, Financial, Conversion, Miscellaneous
We can see each and every one very detail in following.


Globals
Global expressions executes/works in Page Header and Footer parts only.
ExecutionTime shows date and time at when report executes
PageNumber shows page number of each and every page but allowed only in page header and footer
ReportName displays name of the active report what name we have assigned to the active report
UserId shows current user name like company/alirazazaidi
Language displays language like US-English…
Operators
Arithmetic
^ power of
* multiplication
/ divides two numbers and returns a floating point result
\ divides two numbers and returns a integer result
Mod divides two numbers and returns remainder only
+ adds two numbers and concatenation for two strings
- subtraction and indicates negative value for numeric values
Comparison
Known operators : < <= > >= <> 
Like compares two strings and return true if matched or else returns False. Ex: =Fields!Title.Value Like Fields!LoginID.Value
Is compare two object reference variables Ex: = Fields!Title.Value Is Null
Concatenation
+ and & symbols uses for concatenation
Logical
Known: And, Not, Or 
Xor SELECT * FROM users where firstname = ‘Larry’ XOR lastname = ‘Smith’
AndAlso First condition will check first and if it is true only, goes to next or else it won’t need to check. Because our execution time is saving in a logical operation in which more conditions is combined using AndAlso function.
OrElse same like above

change date time format in SSRS report in AX 2012

Today is another small tip,
I was developing a custom report. Queried table stored the date and time in separate fields ie. Transdate and transtime. On  mapping the transtime to report, its showed time format. Instead of time value.
2016-10-28_19-18-27
For it solution, I added the string field on report temp table and then convert the time with time2str function and map to the field.
Complete statement is below.
TableTmp.StransTime  = time2Str(_Trans.transTime, TimeSeparator::Colon, TimeFormat::AMPM);

As result, report will display the trans time instead of its format.

Full text index in AX 2012

Consider following points for Full text index on Dynamics Ax 2012
  • Full text index used only on text fields on table.
  • They find all records from table which contains the key words
  • Queries can be used to and full text index used in range filters
  • If keywords contains spaces then it will used as “Or” operator.
  • X++ select statement cannot use full text index.

Let explore the full text index on our custom table “HSPatientTable”
2015-08-23_1-55-28
And we want full index search of FName of above mentioned table. First of all right click on table and from property window set table group property to “Main”.
2015-08-23_1-58-16
Now expand the full text Index node of table and create a new full index name it as IdxFName and drag drop the Fname in this index.
2015-08-23_2-00-55
Compile and synchronize table so changes reflect at sql server level.

Now create Now Ax job and paste following code there
static void Job1(Args _args)

{

HsPatientTable patientTable;

Query query;

QueryBuildDataSource queryBDSource;

QueryBuildRange queryBRange;

QueryRun queryRun; 

delete_from patientTable;

patientTable.HsPatientId ="01";

patientTable.FName =" Ali Raza zaidi";

patientTable.insert();

patientTable.HsPatientId ="02";

patientTable.FName =" Ranjah jogi";

patientTable.insert();

patientTable.HsPatientId ="03";

patientTable.FName ="Waseem akahram";

patientTable.insert();

patientTable.HsPatientId ="04";

patientTable.FName ="Shah jii";

patientTable.insert();

patientTable.HsPatientId ="05";

patientTable.FName ="AX guru";

patientTable.insert(); 

query = new Query();

queryBDSource = query.addDataSource(tableNum(HsPatientTable));

queryBRange = queryBDSource.addRange(fieldNum(HsPatientTable, FName));

 

queryBRange.rangeType(QueryRangeType::FullText);

 

// The space character is treated as a Boolean OR.

queryBRange.value("AX jii");

 

 

queryRun = new QueryRun(query);

while (queryRun.next())

{

patientTable = queryRun.get(tableNum(HsPatientTable));

info (" Patient Id: "  + patientTable.HsPatientId + " , Patient Name: " +patientTable.FName);

}

 

}
I used the value “AX jii”. The space between two words consider as Or and in result it will return two records

How to create SSRS report using Report data provider (RDP Report) in AX 2012
