How to: Get field values from dynamically loaded tables

If you need field values from different tables at runtime within the same function, then there is a nice solution:

 

// variables
tableType, Option : CompInfo,PayTerm
result : ARRAY [5] OF Variant 

OnRun()
LoadDynamicallyFieldValues(tableType::CompInfo, result);
MESSAGE(FORMAT(result[1])+', '+FORMAT(result[2])+', '+FORMAT(result[3]));
LoadDynamicallyFieldValues(tableType::PayTerm, result);
MESSAGE(FORMAT(result[1])+', '+FORMAT(result[2])+', '+FORMAT(result[3]));

LoadDynamicallyFieldValues(tableType : 'CompInfo,PayTerm';VAR result : ARRAY [5] OF Variant)
CASE tableType of
 tableType::CompInfo:
 begin
  compInfo.GET;
  recID := compInfo.RECORDID;
  GetFieldValue(recID,'Name',result[1]);
  GetFieldValue(recID,'Address',result[2]);
  GetFieldValue(recID,'City',result[3]);
 END;
 tableType::PayTerm:
 BEGIN
  payTerm.FINDFIRST;
  recID := payTerm.RECORDID;
  GetFieldValue(recID,'Code',result[2]);
  GetFieldValue(recID,'Discount %',result[3]);
  GetFieldValue(recID,'Description',result[1]);
 END;
END;

GetFieldValue(recID : RecordID;fieldName : Text;VAR fieldValue : Variant)
recRef.GET(recID);
field.SETRANGE(FieldName,fieldName);
field.SETRANGE(TableNo,recID.TABLENO);
IF field.FINDFIRST THEN BEGIN
 fieldRef := recRef.FIELD(field."No.");
 fieldValue := fieldRef.VALUE;
END;

Get next object version number

Every developer has sometimes the issue: What is my next version number for the new object ? If there is a couple of developers working in the some database, you’ll need a kind of a version control.

I’ve developed a page, which calculates the next version number for a defined version prefix. The version sytax is: <PREFIX><Main No.>.<2-digit Sub No.>.

Let’s start with a list of pages with different version list, version ARCH1.00 to ARCH1.06. It does not matter, if the version list of an object contains more than one value.

After running the page set the version prefix, here ARCH, and push action “Get next version”. We get then the new version: ARCH1.07.

You can download the page here.

 

Export Nav Objects by Code

Exporting locked nav objects can be a problem when importung in target database. it’s not that easy to unlock them in the target database. So for that you can export nav objects by code and check Lock status before exporting.

Create a new report, add dataitem Object. set report to processingonly.

pic1

select dataitem Object, set property ReqFilterFields to Type,ID.
set request page: add field Path (Text).

pic2

add following code to trigger OnOpenPage:

Object.SETRANGE(Type,Object.Type::Table);
Path := 'c:\temp';

add following code to report trigger OnPreReport():

finsql := 'C:\Program Files (x86)\Microsoft Dynamics NAV\100\RoleTailored Client\finsql.exe';
IF NOT FILE.EXISTS(finsql) THEN
  ERROR('finsql not found');

additional add that code to trigger Object – OnAfterGetRecord():

IF Object.Locked THEN BEGIN
  Message(FORMAT(Object.Type)+'-'+FORMAT(Object.ID)+' is locked.');
  // alternatively unlock object, then try again.
  // Object.Locked := FALSE;
  // Object.MODIFY;
end ELSE begin
  arguments := 'command=exportobjects,file=%1,servername=%2,database=%3,filter="Type=%4;ID=%5",ntauthentication=1';
  arguments := STRSUBSTNO(arguments,Path+'\'+FORMAT(Object.Type)+'-'+FORMAT(Object.ID)+
'.fob','localhost','Cronus',Object.Type,Object.ID);
  Process.Start(finsql,arguments);
  result := result + FORMAT(Object.Type)+'-'+FORMAT(Object.ID)+'\';
END;

to trigger Object – OnPostDataItem():

MESSAGE(result);

Global Variables:

Process DotNet System.Diagnostics.Process.'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
arguments Text
finsql Text
Path Text

How to: Get record count for all tables

In newer Nav versions the tables overview in development environment/database information has gone. So how to get that list back ?

Let’s got to SSMS (Sql Server Management Studio).
There select the database, for which you want that information.
Right click on database -> Reports -> Standard Reports -> Disk usage by Top Tables

enter image description here

There we are ! 😉

 

Import with Rapid Start Services

The Rapid Start Services are an often used tool in Dynamics Nav to export and import data. In that posting i show how the Import works using new feature Item Attributes.

In that sample i want to import a new Item Attribute Value and a new Item Attribute Value Mapping. Item Attribute Values are the concrete values, which an Item Attribute can have, e.g. Item Attribute “Color” can have values red, green, blue. These values can now be added as attributes to a concrete item using table item attribute value mapping.

We start with a new Config. Package. So goto /Departments/Administration/Application Setup/RapidStart Services/Configuration Packages or simply write “Configuration Packages” into the search box. There create a new Config. Package and set ITEMATT as code value and “Item Attributes” as package name. Now we add some lines to the Tables list: 7501 and 7505.

cfg4

Now select Filters in subpage menu Table.
Add a filter for the first line (table 7501). Here we want to filter for Item Attribute with ID 1 (Color): FieldID = 1,Field Filter = 1.
For the 2. line (table 7505) set following filter:

cfg5

Now export the filtered table data to excel using action “Export to Excel” from the main menu Actions. Open the created excel document. So we get the needed format to import some data. Now we change the data. Remove all data lines from table 1 in the excel document except line 1. Now change the values for ID and Value as follows:

cfg2

In the 2. table change the value for “Item Attribute Value ID”:

cfg3

Save the changed document to your documents folder, close Excel. Now we can import the new data. For that click on “Import from Excel”, No. of Package records changes to 1. If you click on the no., you can check import errors in the winow Config. Package records. The imported data is now temporarily saved. To save the data to the target tables, click on “Apply Package” action.

cfg1

Now let’s check, if the data was imported.

cfg6

Goto items list and click on action Attributes in menu Action. All right, the data is correct. You see in the second line Attribute Farbe (= Color) and the new value Brown, right the attribute value list with the new value.

How to work with big item descriptions

Sometimes it’s needed to save very long descriptions, but in Nav text fields can have only 250 characters. Additional you may want to search in these long text values. You can add a couple of these text fields to save long texts or save the text in text files and add them to the item. But what about searching? Not that easy.
An other option to save long texts is the usage of blob fields. For that option i developed a solution.

First add a new field “Description 3” to table Item, type BLOB, subtype Memo.
Then edit page Item Card, add a global variable Desc3Txt of type text with no length. Add the variable as new field to the item card, Editable=False, MultiLine=Yes.
Add following code to trigger OnAfterGetRecord in item card page:

// InStr | InStream
CALCFIELDS("Description 3");
IF "Description 3".HASVALUE THEN BEGIN
  "Description 3".CREATEINSTREAM(InStr);
  InStr.READ(Desc3Txt);
END;

Add to trigger Desc3Txt – OnAssistEdit()

// OutStr | OutStream 
// EditCtrl | DotNet | Archer.TextEdit.'Archer.TextEdit, Version=1.0.0.0, Culture=neutral, PublicKeyToken=1465b259ee2284cb' 
CLEAR(EditCtrl);
EditCtrl := EditCtrl.TextEdit;
EditCtrl.Load(Desc3Txt);
EditCtrl.ShowDialog;
Desc3Txt := EditCtrl.Save;
EditCtrl.Close;
CLEAR(EditCtrl);

"Description 3".CREATEOUTSTREAM(OutStr);
OutStr.WRITE(Desc3Txt);
MODIFY;
CurrPage.UPDATE;

itse-1

Page item card with new multiline text field “Description 3” and Assist Button.

itse-2

Clicking on Assist Button starts the TextEdit Control and loads the current text. After changing the text and closing the text control, you are asked, if you want to change the text.

Now we need the opportunity to search within the new text/blob field. For that we need a new page Item Search. That new field cannot be searched using the standard search function.

Create a new page with objectid 50000, name Item Search. Add a group under the contentarea, add a global text variable SearchString, add a new field under the group with SearchString as SourceExpr. Add another group, add a new line with type part. Later we set the value for property PagePartID.

itse-3

To show the search result we need another page: type listpart, objectid 50001, name Item Search Result. As source of the new page we need a new table: objectid 50000, name Item Search Result.

itse-4

The new page 50001:

itse-5

Properties: Editable=False, SourceTable=50001, SourceTableTemporary=Yes.

Now add global function SetData(SearchFilter : Text) to the new page. Add following code to the new function:

// local variables
// Item, Record, Item 
// ItemSearchResultLine, Record, Item Search Result 
// InStr, InStream 
// Desc3Txt, Text 
// LineNo, Integer 

DELETEALL;

LineNo := 10;
Item.FINDSET;
REPEAT
  Item.CALCFIELDS("Description 3");
  IF Item."Description 3".HASVALUE THEN BEGIN
    Item."Description 3".CREATEINSTREAM(InStr);
    InStr.READTEXT(Desc3Txt);
    IF STRPOS(LOWERCASE(Desc3Txt),LOWERCASE(SearchFilter)) > 0 THEN BEGIN
      "Line No." := LineNo;
      "Item No." := Item."No.";
      Description := Item.Description;
      "Description 2" := Item."Description 2";
      "Description 3" := COPYSTR(Desc3Txt,1,250); // first 250 chars
      INSERT(FALSE);
      LineNo += 10;
    END;
  END;
UNTIL Item.NEXT = 0;

CurrPage.UPDATE(FALSE);

Now you can set the property PagePartID in the part line in page 50000 to 50001.

For calling the search function we need a Search button in page 50000.
Add following code to trigger Search – OnAction()
CurrPage.ItemSearchResultLines.PAGE.SetData(SearchString);

itse-6

The new Item Search Page with a search result.

You can download the TextEdit Control here.

Followup:
You could simplify the solution by:
* Search page: Use only page 50001, add a second group at the top with field SearchString. So page 50000 is not needed.
* Page Item Card: remove the textedit control and the according code, set field Desc3Txt to editable, add the code to fill the blob field “description 3” using outstream to trigger Desc3Txt-OnValidate.

Error when opening Whse. Shipment page

Got following error after creating a Whse. shipment from a sales order in Nav 2017 when opening the Whse. Shipment from page “Whse. Shipment Lines”:

The record that you tried to open is not available. 
The page will close or show the next record.

The first strange thing is, the message is an info box, not an error message. After analysing the data in the sales order and tables Whse. Shipment Header and Whse. Shipment Line no error found. So what’s up? Also debugging did not really help, the debugger did not jump to the line, where the info box is created.

In the end i found out, that the reason for the strange behaviour was following: I created a new location for some tests, but forgot to add my user to the whse. employees, but that was not shown. The causal reason in the code: When opening page 7335 Whse. Shipment from page “Whse. Shipment Lines” following code is called in OnOpenPage trigger:

ErrorIfUserIsNotWhseEmployee() // from table 7320 Whse. Shipment Header
IF USERID = '' THEN BEGIN
  WhseEmployee.SETRANGE("User ID",USERID);
  IF WhseEmployee.ISEMPTY THEN
   ERROR(Text002,USERID);
END;

Nice code, but what happens, if WhseEmployee.ISEMPTY is not empty? No error message is shown, but the info message from above with senseless text, which has nothing to do with the original error. Here it’s not checked, if there is a whse. employee created for the current user and the given location of the sales order. Thx microsoft.

What’s needed to correct the behaviour? Change above code to:

IF USERID = '' THEN BEGIN
  WhseEmployee.SETRANGE("User ID",USERID);
  WhseEmployee.SETRANGE("Location Code","Location Code");
  IF WhseEmployee.ISEMPTY THEN
    ERROR(Text002,USERID);
  END;

You should also change Text002 to “You must first set up user %1 as a warehouse employee for location %2.”.
