I have got a Table called Category with the following field;
Share
Report field(50000; "Code"; Code[50])
{
DataClassification = CustomerContent;
}
field(50001; "Description"; Text[100])
{
DataClassification = CustomerContent;
}
field(50002; "Group"; Code[50])
{
DataClassification = CustomerContent;
TableRelation = Group;
}
and a Table called Group with the following fields;
field(50000; "Code"; Code[50])
{
DataClassification = CustomerContent;
}
field(50001; "Description"; Text[100])
{
DataClassification = CustomerContent;
}
I have list pages for those two tables I mentioned above for the user to enter data.
Note that every Category has a Group hence the TableRelation of Group as one of its fields in the table.
I have a Page that users get to select values of Group and Category;
page 50118 "Code Selection"
{
PageType = StandardDialog;
ApplicationArea = All;
UsageCategory = Administration;
layout
{
area(Content)
{
group(Select)
{
field(Group; Group)
{
ApplicationArea = All;
TableRelation = Group;
}
field(Category; Category)
{
ApplicationArea = All;
TableRelation = Category;
}
}
}
}
actions
{
area(Processing)
{
}
}
var
Group: Code[50];
Category: Code[50];
Rec_Item: Record Item;
NoSeriesMgmt: Codeunit NoSeriesManagement;
NoSeriesCode: Code[30];
ItemNo: Code[30];
Page_Item: Page "Item Card";
trigger OnQueryClosePage(CloseAction: Action): Boolean
begin
NoSeriesCode := 'ITEM2';
IF Confirm('Do you create new Item?') THEN BEGIN
IF Group = '' then begin
Error('Group cannot be empty.');
end;
IF Category = '' then begin
Error('Category cannot be empty.');
end;
Clear(NoSeriesMgmt);
Clear(Rec_Item);
Clear(Page_Item);
Rec_Item.Init();
ItemNo := NoSeriesMgmt.GetNextNo3(NoSeriesCode, TODAY, true, false);
ItemNo := UpperCase(Group) '-' UpperCase(Category) '-' ItemNo;
Rec_Item."No." := ItemNo;
Rec_Item.Category := Category;
Rec_Item.Group := Group;
Rec_Item.Insert(true);
Page_Item.SetTableView(Rec_Item);
Page_Item.SetRecord(Rec_Item);
Page_Item.Run();
END
ELSE BEGIN
Message('Item creation cancelled.');
END;
end;
}
I use this page to then do something with Item page's No. field.
However, what I am stuck at is, I want to filter the records of Category based on Group when the user is doing a lookup on Category.
Since the Category has Group attached to it, lets say record in Category looks like this;
Record 1) ABC[Code XXX[Group
Record 2) DEF[Code XXX[Group
Record 3) GHI[Code YYY[Group
Record 4) JKL[Code YYY[Group
Now in the Page I have created; if the user selections Group to be XXX, I want the Category table relation to show only records Record 1 and Record 2.
And if user selected Group to be YYY Category show only records Record 3 and Record 4.
Basically, filter the look up records of Category based on the value selected in Group.
I tried writing on Table Relation if(Group = const('XXX) Category where(Group = Filter('XXX))
and it did not work.
