Scripts

These scripts are intended for use only when Auto Config does not work in your Salesforce org. They are not required for most customers.

Creating the GRAX_Integration_User Permission Set manually

1. Open the Salesforce Developer Console

2. Open the Debug menu

3. Select Open Execute Anonymous Window (or press CTRL + E)

4. Copy the script below into the Enter Apex Code dialog

5. Select the Open Log checkbox

6. Click Execute

7. Assign the new 'GRAX_Integration_User' permission set to the GRAX Integration User.

PermissionSet piu = new PermissionSet(
    Name = 'GRAX_Integration_User',
    Label = 'GRAX Integration User Permission',
    Description='Grants users permission to read and update records, fields and files for GRAX backup, archive and restore',
    PermissionsApiEnabled=true,
    PermissionsViewAllData=true,
    PermissionsModifyAllData=true,
    PermissionsQueryAllFiles=true
);

DescribeSobjectResult permissionSetDescribe = Schema.PermissionSet.SObjectType.getDescribe();
Map<String, SObjectField> fieldMap = permissionSetDescribe.fields.getMap();
List<String> availablePermissions = new List<String>();

for (String fieldName : fieldMap.keySet()) {
    if (!fieldName.startsWithIgnoreCase('Permissions')) {
        continue;
    }
    if (fieldName == 'PermissionsCreateAuditFields') {
        System.debug('Setting PermissionsCreateAuditFields=true');
        piu.put(fieldName, true);
    }
    if (fieldName == 'PermissionsViewAllData' ||
            fieldName == 'PermissionsModifyAllData' ||
            fieldName == 'PermissionsQueryAllFiles') {
                continue;
    }
    DescribeFieldResult fd = fieldMap.get(fieldName).getDescribe();
    if (fd.isCreateable() && fd.isUpdateable()) {
        availablePermissions.add(fieldName);
    }
}
Integer count = 1;

while (count < 11) {
    try {
        insert piu;
        count = 100;
    } catch(DmlException e) {
        count++;
        List<String> splitError = e.getMessage().split(' ');

        for (String str : splitError){
            string check = str.removeEnd(',');
            check = check.removeEnd(':');
            for (String fieldName : availablePermissions){
                if (fieldName == 'Permissions' + check){
                    piu.put(fieldName, true);
                }
            }
        }
    }
}

Fixing Field Level Security manually

Option 1: Apex FLS Script

The GRAX-provided Apex script below is an effective solution for updating field-level permissions on a large number of objects. However, there are a few cases in which the script may not be ideal:

1. Very large number of objects

2. Very large number of fields

The script makes a best effort to handle Apex row/batch limits. This means that you need to run the script multiple times if a large number of objects are processed. The script outputs Apex batch limits reached. Please run again for next batch. if another run is required.

If you encounter Apex limit errors, errors related to specific objects, or validation errors while running this script, fallback to the web-tools option below for updating the objects that remain.

NOTE: this section assumes you've used the script above to provision a GRAX_Integration_User Permission Set. If you don't have a permission set with this name in your org, the script fails.

ALSO NOTE: this script grants access to fields we're able to find in the Salesforce metadata. This may not be a comprehensive list. GRAX Admins should review the GRAX_Integration_User Permission Set's Field Permissions for each object to ensure access is granted to all fields.

Running the FLS Script

1. Open the Salesforce Developer Console

2. Open the Debug menu

3. Select Open Execute Anonymous Window (or press CTRL + E)

4. Copy the script below into the Enter Apex Code dialog

5. Select the Open Log checkbox

6. Click Execute

7. In the Execution Log window, select the Debug Only checkbox

8. If the last log entry prompts a re-run, return to the Execute Anonymous Window and repeat the subsequent steps until the last entry no longer prompts a re-run.

// decrease the maxBatchSize if a `System.LimitException: Too many query rows: 50001` error is returned
Integer maxBatchSize = 1000;

PermissionSet[] lpsGIU = [SELECT Id FROM PermissionSet WHERE name = 'GRAX_Integration_User'];
if (lpsGIU.isempty()) {
    System.debug('GRAX_Integration_User PermissionSet not found');

Option 2: Web-tools Script Builder

GRAX Web-tools can generate an FLS script that is scoped to a single-object at a time. This prevents many issues with Apex limits that may result from the larger script above while still making life easy for SFDC admins.

Generating and Running a Script

1. Navigate to /web/tools on your GRAX Application, or use the link at the top right of the Settings page

2. Select the Missing Field Permissions option

3. Select the Show Apex Script option for the intended object

4. Copy the generated script to your clipboard

5. Open the Salesforce Developer Console

6. Open the Debug menu

7. Select Open Execute Anonymous Window (or press CTRL + E)

8. Copy the script below into the Enter Apex Code dialog

9. Select the Open Log checkbox

10. Click Execute

11. In the Execution Log window, select the Debug Only checkbox

12. The script outputs the number of corrected fields in the last log line.

Repeat the steps above for each necessary object.
