how to modify values in a custom field in Res. Ledger entry

(2) ShareShare
ReportReport
Posted on by gnlca 22
Hi everyone,
I created a new field called TestField in the table Res. Ledger entry.
Is there a way to modify the value in TestField via a procedure? For example I could create an action on the Resource Ledger Entries page which for each record in the table Res. Ledger entry copies the Entry No. to the TestField.
 
Thank you and best regards

    Hi @gnlca,
     
    Yes you can flow these steps :
    1 Table Extension (Res. Ledger Entry)
    tableextension 50109 "Res. Ledger Entry Ext" extends "Res. Ledger Entry"
{
    fields
    {
        field(50100; TestField; Integer)
        {
            Caption = 'Test Field';
            DataClassification = ToBeClassified;
        }
    }
}
    2 Page extension (Resource Ledger Entries)
    pageextension 50109 "Resource Ledger Entries Ext" extends "Resource Ledger Entries"
{
    layout
    {
        addafter("Entry Type")
        {
            field(TestField; Rec.TestField)
            {
                ApplicationArea = All;
            }
        }
    }

    actions
    {
        addbefore("&Navigate")
        {
            action(PopulateTestField)
            {
                ApplicationArea = All;

                trigger OnAction()
                var
                    ResLedgerEntry: Record "Res. Ledger Entry";
                begin
                    if (ResLedgerEntry.Get(Rec."Entry No.")) then begin
                        ResLedgerEntry.TestField := ResLedgerEntry."Entry No.";
                        ResLedgerEntry.Modify();
                    end;
                end;
            }
        }
    }
}
    Best regards,

    Hi Mohamed,
    the code you proposed I already tried myself but it fails because the table Res. Ledger Entry is read only.
    The key is to make either the field TestField write enable and/or to catch the system method that is preventing my code to modify the value.
     
    Thank you and best regards,

    Hi @gnlca,
    You're right. 
    In that case I suggest you create a codeunit and add a permission set (Permissions = TableData "Res. Ledger Entry" = RMID) to it.
    pageextension 50109 "Resource Ledger Entries Ext" extends "Resource Ledger Entries"
{
    layout
    {
        addafter("Entry Type")
        {
            field(TestField; Rec.TestField)
            {
                ApplicationArea = All;
            }
        }
    }

    actions
    {
        addbefore("&Navigate")
        {
            action(PopulateTestField)
            {
                ApplicationArea = All;

                trigger OnAction()
                var
                    test: Codeunit Test;
                begin
                    test.UpdateTestField(Rec."Entry No.");
                end;
            }
        }
    }
}
    Codeunit
    codeunit 50105 Test
{
    Permissions = TableData "Res. Ledger Entry" = RMID;

    procedure UpdateTestField(EntryNo: Integer)
    var
        ResLedgerEntry: Record "Res. Ledger Entry";
    begin
        if (ResLedgerEntry.Get(EntryNo)) then begin
            ResLedgerEntry.TestField := ResLedgerEntry."Entry No.";
            ResLedgerEntry.Modify();
        end;
    end;

}
