We use in our org case sharing (Setup-->Security Controls-->Sharing Settings-->Case (Default Internal Access From Public Read/Write/Transfer to Private))

Wa want this sharing settings in place when we create our scratch orgs, Is there a way to achieve that by sfdx cli command or some config in the project-scratch-def.json file?

After some searches, i have locate the information by SOQL:

Organization o = [Select DefaultCaseAccess from Organization];

But i can't update it by apex code for example

o.DefaultCaseAccess = 'None';

The field is not writable:

Field is not writeable: Organization.DefaultCaseAccess

Thank you for your help;


Probably a bit late but better than never.

You can use sfdx force:mdapi:deploy -d data/standard-object-stub/ -w 1 -u $SCRATCH_ORG_ALIAS with a package.xml that references a Case.object file with the following content in a objects subfolder before you deploy your sources

<?xml version="1.0" encoding="UTF-8"?>
<CustomObject xmlns="http://soap.sforce.com/2006/04/metadata">

This will only change the sharing setting, which will take some time so you might want to delay the further steps like package installation or source push a bit.

Update 12/2019:

Within the topic of unlocked packaged (that might have managed packages with certain OWD sharing settings as a dependency) I've come across a probably interesting known issue in this field:


That known issue raises hopes on better support for changing OWD sharing settings based on scratch org definition files.

Update 09/2020:

Actually that got improved recently, you can use the scratch org definition file:

  "orgName": "Scratch Org",
  "edition": "Developer",
  "features": [
  "settings": {
    "accountSettings": {
      "enableAccountTeams": true
  "objectSettings": {
    "opportunity": {
      "sharingModel": "private"
    "account": {
      "sharingModel": "read"
    "case": {
      "sharingModel": "read"
    "contact": {
      "sharingModel": "private"
