For ex.
try putting your rdl in the folder inside your project ('./JobLayoutModify.rdl').
the source rdl file is located within the folder C:\Users\yoursUsers\Documents\AL\Test.alpackages\Microsoft_Base Application_20.5.45456.47775\src\JobLayout.rdl
When you find the file make a copy and insert the modified (.rdl) file into your project. as done in the example.
report 50000 ATC_RD_Job
{
Caption = 'job view', comment = 'ITA=" Visualizzazione commesse"';
UsageCategory = Administration;
ApplicationArea = All;
DefaultLayout = RDLC;
RDLCLayout = './JobLayoutmody.rdl';
dataset
{
dataitem(Job; Job)
{
column(No_; "No.") { }
column(Description; Description) { }
column(Creation_Date; "Creation Date") { }
}
}
requestpage
{
layout
{
area(Content)
{
group(GroupName)
{
field(Commessa; Job."No.") { }
}
}
}
}
I hope I have helped
