RDLC problem-can not show serial number

Posted on by Lisa2022

Hi，

I want to show serial no of released production order on job card(99000762), so I generate a report extention as below; After upload it the serial no can be shown on the word layout, but not on RDLC. I don't know the reason.

Please help to check the AL of the report extention.

reportextension 50104 MyJobCard extends "Prod. Order - Job Card"
{
dataset
{
addlast("Production Order")
{
dataitem("Reservation Entry"; "Reservation Entry")
{
DataItemLink = "Source ID" = field("No.");
DataItemLinkReference = "Production Order";
column(Serial_No_; "Serial No.")
{
}
}
}
}
}
