Add the value of a new custom field to another related table

Posted on by MartinaHawkins

Hi,
I have added a custom field called Item Description to the item table as the current Description field is too short

I want the value of this field to show (that was entered in the item card page) in the Blanket Purchase Order when I select an item

I can get it to show as a Flow field but I don't want this as it needs to be editable. I just want to show this new field in the same way as the currrent Description shows.

Any help appreciated. Tried some trigger OnAfterGetRecord() code in the page extension of the Blanket Purchase Order but didn't work

Hi,

I think you use OnValidate trigger to populate your new custom field.

for old records you need to create a few code to update the new field.

I would suggest you to use standard Description 2 field if you are not already using so you dont have to do any development.

Back to your question :)

The Item field values are copied to purchase line in a CopyFromItem function of Table 39

You can subscribe to OnAfterAssignItemValues event/publisher and update your field.

Got it to work. Is there anything I am missing? Description 2 is only 50 characters

addafter("Item No.")
{
field("Item Description KGS"; Rec."Item Description KGS")
{
ToolTip = 'Item Description';
ApplicationArea = all;
}
}

trigger OnAfterGetRecord()

begin
SetMyStyle();

Desc.reset;
Desc.SetRange("No.", Rec."Item No.");
If Desc.FindFirst() then begin
rec."Item Description KGS" := Desc."Item Description KGS";
end;
end;

procedure SetMyStyle()
begin
if (rec."Item Status KGS" = 'Risky') then
Mystyle := 'Unfavorable' else
Mystyle := 'Standard';
end;

var
MyStyle: Text;
Desc: Record "Item";

In Business Central, there is a feature for extended descriptions in the Item card. I suggest you try that function to see if it fulfills your requirements.

Personally, I do not recommend this customization because there are too many tables related to Item Description.

Even if you add new fields and add this function to Blanket Purchase Order, only these two places are available, and the standard Item Description will still be displayed in other features.

In addition, this is also related to the posting code. If you assign a value of length 500 to a field of standard length 100, an error will be prompted or the first 100 characters will be automatically taken.

As for the problem you mentioned, you can refer to the following way.

Thanks
