Hello everybody,

today I want to leave a short note on how to use F-BQL version of PXSelect in Acumatica.

In past it was common to have this line of code in your graph:

public PXSelect<Student1> Students;

In new F-BQL introduced new construction, SeleftFrom. Proper way of using it is this:

public SelectFrom<Student2>.View Students;

Take notice of suffix .View. Without that suffix you'll not get proper F-BQL view. And Acuminator will give you this warning:

So if to summarize, don't forget to add suffix .View

Hello everybody,

here is just short post on how to download DAC Schema browser which I recently opensourced.

You'll need two steps:

1. Navigate in your browser to link https://github.com/YuriyZaletskyy/DacSchemaBrowser 2. Click on Star as displayed on screenshot (this is optional step):

       4. Right mouse click AcumaticaTablesFixed19x100x0122.zip

       5. Save customization wherever you wish

       6. Publish on your local instance

That particular file is intended for Acumatica version 2019 R1 build 0122, but it should work on higher versions as well. Later on I'll add lower versions as well.

Hello everybody,

today I want to share single line of code, which I found recently while digging Acumatica source code with reflector. Sometime you may need to know if there is some or antoher Acumatica table available. For example if you create some customization plugin. How to find out if there is some table? You can use following line of code for this purpose:

using PX.Api.Soap.Screen;

............

var acumaticaTables = ServiceManager.Tables;

Variable acumaticaTables will have a list of Acumatica tables.

Hello everybody,

once upon a time Acumatica requires for certified developers to pass over certification again. 

As obedient person I decided to install T100 sample application over Acumatica Framework Configuration ( don't mix with Acumatica ERP Configuration ). Then I navigated to just installed application, and here is what I've seen:

Line 283:    <siteMap>
Line 284:      <providers>
Line 285:        <add name="MySqlSiteMapProvider" type="MySql.Web.SiteMap.MySqlSiteMapProvider, MySql.Web, Version=8.0.13.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="LocalMySqlServer" applicationName="/" />
Line 286:      </providers>
Line 287:    </siteMap>

Very puzzling honestly speaking. You've just installed something, and right from the start it doesn't work. 

After some Research I have found, that following some additions should be added to node siteMap section providers:

			<siteMap enabled="true" defaultProvider="PXDatabaseSiteMapProvider">
				<providers>
			            <remove name="MySqlSiteMapProvider" /> <!-- add this line --> 
			            <remove name="PXWikiProvider" />

After those additions I was able to open Training sample T100.

Hello everybody,

Today I want to leave a short notice on how to call Cancel button of Acumatica from inside C# code:

graph.Clear();

That is it, Clear method is binded to button Cancel in Acumatica. Besides that Clear method will reload current data record from database and rolls back changes of Cache objects.

Hello everybody,

today I want to say a bit more about usage of attribute PXUIRequired as previous article on my blog wasn't very easy to follow by some of my readers.

Take a look on presented code sample:

public class sOOrderType : Constant<string>
{
	public const string SOOrderType = "SO";
	public sOOrderType() : base(SOOrderType)
	{	
	}
}
 
public class SOOrderExt : PXCacheExtension<SOOrder>
{
	[PXMergeAttributes(Method = MergeMethod.Append)]
	[PXDefault]
	[PXUIRequired(typeof(Where<SOOrder.orderType, Equal<sOOrderType>>))]
	public virtual string CustomerOrderNbr { get; set; }
}

As you can see, besides attribute PXUIRequired it has declaration of constant value "SO". With that declaration before class you may get validation only for SO Order type "SO".

And now as you see on screenshot, field Customer Order got it's star. Take notice that color of that star is also differnet, it become red.

One more point which I want to underline, attribute PXUIRequired will work in connection with PXDefault attriubute. Without PXDefault attribute you'll get another error message, so as as summary, use PXUIRequired attribute with PXDefault.

Hello everybody,

Today I want to note that SQL Server has following order of processing:

1. From
2. Where
3. Group by
4. Having
5. Select
6. [Expressions]
7. [Distinct]
8. Order By
9. [TOP/OFFSET-FETCH]

By looking on this order you may understand why in C# LINQ from goes first and not select. That is because C# is imperative language, while SQL is declarative.

Hi everybody,

today I want to give one more definition of Group by of SQL language which for me is very explanatory.

Group by statement produces a record for each unique combination of group by columns list and ommiting other columns of tables.

Also you can apply aggregate functions to other columns. Aggregate functions may be count, sum, avg, mean, max, etc.

And each of the functions will be executed against columns of groupped records.
