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

There we are ! 😉

 

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;

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

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.

Mass data import

There was an issue with importing all UK post codes from a csv file, about 3m post codes. Importing using rapidstart services (excel import) can cause buffer overflow messages. excel itself has row/size limitations. Increasing MaxNoOfXMLRecordsToSend in config file ClientUserSettings.config from default value 5000 to e.g. 20000 is no problem and can help. Also changing MaxUploadSize in server config file CustomSettings.config is an option (also available via nav service admin console). Better choice for mass data import are dataports (older nav versions) and xmlports.

Another option is to develope a report, which imports the file contents and loops through the lines. quite simple, no memory issues.

create a new report, add following code to trigger OnPreReport():

OnPreReport()
// variables
 PostCode, Record, Post Code
 file, File
 fileName, Text, 250
 line, Text, 1024
 dlg, Dialog
 idx, Integer
 txtValue, Text, 100
// code
 PostCode.DELETEALL(FALSE);
 COMMIT;
 dlg.OPEN('#1###### #2######'); // show progress dialog
 idx := 1;

// downloaded post code file from https://www.doogal.co.uk/PostcodeDownloads.php
// as test file, size: 500k, 2.1m lines, some of them contain obsolete post codes
 fileName := 'c:\temp\England postcodes.csv';

 file.WRITEMODE := FALSE;
 file.TEXTMODE := TRUE;
 file.OPEN(fileName);
 file.READ(line); // skip header line
 WHILE file.READ(line) > 0 DO BEGIN
   // skip obsolete post codes: 2. value = No
   IF SELECTSTR(2,line) = 'Yes' THEN BEGIN 
     PostCode.Code := SELECTSTR(1,line);
     PostCode.VALIDATE(City,GetValue(SELECTSTR(15,line)));
     PostCode.County := GetValue(SELECTSTR(8,line));
     PostCode."Country/Region Code" := 'GB';
     PostCode.INSERT;
     dlg.UPDATE(1,idx);
     dlg.UPDATE(2,PostCode.Code);
     idx += 1;
   END;
 END;

 file.CLOSE;
 dlg.CLOSE;

 MESSAGE(FORMAT(idx) + ' post codes imported.');

LOCAL GetValue(txtValue : Text[100]) : Text
 txtValue := DELCHR(txtValue,'<','"'); // remove leading "  
 txtValue := DELCHR(txtValue,'>','"'); // remove trailing "
 IF STRLEN(txtValue) > 30 THEN // fields City,County are Text[30]
   txtValue := COPYSTR(txtValue,1,30); // cut text, leading 30 chars

 EXIT(txtValue);

report runs with 1.5m valid lines/records about 5 min.

Incoming Documents instead of Links

If you want to add files to a nav document like orders, then you normally use the link factbox. For that you have to link files on file shares, local paths are not allowed (not reachable from other systems). savedocsThat only works, if the current user has the needed permission and the network path is reachable. There is also a problem, if the file is moved, deleted or the permissions were changed.

One alternative to add files to nav documents is the usage of third party components like dms systems (document management systems).

Since Nav 2016 there is the “Incoming Documents” feature available. This is used to add the original scanned document to the purchase order. This document is saved then in the database, not on a file share (network path).

 

The advantages:

  • the nav client is not dependent on permission settings and network issues.
  • No issue with moving and removing of the file on the network path or changing the file permissions.
  • You can use that feature in general to add any kind of file, not only the scanned order.

The disadvantages:

  • No versioning: the same with the links factbox
  • When viewing/editing the added file, changes are not saved back.

To replace an added document (file) you can click on “Incoming Document” in the according factbox. The “Incoming Document” page opens. Here click on Actions/”Replace Main Attachment” and select a different document or a newer version.

salesdocs2

Conclusion:

The feature is a kind of a small dms system with some nice features and interesting advantages compared to the links factbox. You can simply add files to the Incoming documents list, then create a nav document like a purchase invoice with that file as attachment.
