Hello everyone,
i'm struggeling to create a relationship in AL. Maybe someone can help with this or point me in the right direction.
I create a table (A). This table (A) should a have one to one relationship to another table (B). The other table (B) has a composite key based on 5 fields (Fields: V,W,X,Y,Z).
What steps a necessary to create this relationship?
Only one TableRelation on the first field seems not to work and i don't know how to setup the relation with all the other fields.
In the end, i want to select only one field on the page and i want to make sure, that it is the correct relationship.
I hope someone has an idea.
Greetings,
Ben
Hey Zhu,
i found a fitting solution with your link under point "2. Using OnLookup (Field) Trigger and Page.RunModal() Method".
The solution looks like this.
Share
Report
All responses (
Answers (
field(2; V; Code[20])
{
Caption = 'V';
trigger OnLookup()
var
"Table B-Record": Record "Table B";
begin
"Table B-Record".Reset();
if Page.RunModal(Page::"Table B List Page", "Table B-Record") = Action::LookupOK then begin
V := "Table B-Record".V;
W := "Table B-Record".W;
X := "Table B-Record".X;
Y := "Table B-Record".Y;
Z := "Table B-Record".Z;
end;
end;
}
Can you confirm that this solution is viable?
Btw. you can ignore my other post.

Hello Zhu,
thank you for your response.
I just looked at it and i'm not sure if this solution fits for my case.
Unfortunately it is not only about displaying a field accordingly, but to store the key (W,V,X,Y,Z) in table (A), so that I can later find the correct entry in table (B) in a code unit and use the fields of table (B) in my code.
Maybe i misunderstood your solution, could you please explain how to apply your solution to my case?
Greetings,
Ben
