Write here how you think we can improve the tutorial ...

Hello,

I wanted to share some feedback regarding STEP 7 of the tutorial. I struggled a bit due to a few typos and inconsistencies between the position numbers in my code and those presented in the tutorial.

After some troubleshooting, I figured out how to write the code correctly to make it work. Here’s my version of the code, which I hope can help update the instructions so that other learners don’t get stuck like I did:

Complete code from my Metadata Extension:

@Metadata.layer: #CORE

@UI: {
  headerInfo: {
    typeName: 'Travel',
    typeNamePlural: 'Travels',
    title: {
      type: #STANDARD,
      label: 'Travel',
      value: 'TravelID'
    }
  }
}

annotate view Z_I_TRAVEL_R_FMC with
{

  @UI.facet: [ { id:              'Travel',
                  purpose:         #STANDARD,
                  type:            #IDENTIFICATION_REFERENCE,
                  label:           'Travel',
                  position:        10 } ]


  @UI           : {
        lineItem      : [{position: 15, label: 'Agency', importance: #HIGH}],
        identification: [{position: 15 }],
        selectionField: [{position: 15 }]
        }
  AgencyID;

  @UI           : {
        lineItem      : [{position: 20, importance: #HIGH}],
        identification: [{position: 20 }],
        selectionField: [{position: 20 }]
        }
  CustomerID;

  @UI           : {
        lineItem      : [{position: 10, importance: #HIGH}],
        identification: [{position: 10, label: 'Travel' }],
        selectionField: [{position: 10 }]
        }
  TravelID;

  @UI           : {
        lineItem      : [{position: 30, importance: #HIGH}],
        identification: [{position: 30 }],
        selectionField: [{position: 30 }]
        }
  BeginDate;

  @UI           : {
        lineItem      : [{position: 40, importance: #HIGH}],
        identification: [{position: 40 }],
        selectionField: [{position: 40 }]
        }
  EndDate;

  @UI           : {
        lineItem      : [{position: 50, importance: #HIGH}],
        identification: [{position: 50 }]
        }
  TotalPrice;

  @UI           : {
        lineItem      : [{position: 50, importance: #HIGH}]
        }
  Memo;

  @UI           : {
      lineItem      : [{position: 60, importance: #HIGH}],
      selectionField: [{position: 60 }]
      }
  Status;

}

This is the result:

I hope this feedback helps improve the tutorial for future learners. Thank you for your work on this resource!
