Last week somebody asked me on can we extend table relation property and my answer was yes we can achieve this by table extension.

Today we will see how we can do that

Firstly create enum extension and extend as follows . For this demo I used Type field from Sales line table.

enumextension 50145 PlaySaleDocType extends "Sales Line Type"
{
    value(8; Retail)
    {
        Caption = 'Retail';
    }
}

Secondly create a table extension and modify required table relation property.

tableextension 50146 PlaySalesTabRelExt extends "Sales Line"
{
    fields
    {
        modify("No.")
        {
            TableRelation = if (type = const(Retail)) Retail;
        }
    }

}

Hope this will help you.

Stay tuned for more update.
