Conditionally hide the Submit for Approval button in Salesforce Advanced Approvals

The process requires new record types, page layouts, and a flow.

1. Create a new Page Layout and remove the Submit for Approvals button. Use the existing layout with the Submit for Approval button and create a new layout without it. You should now have 2 layouts: One with the Submit for Approval Button and one without.
 

2. Create new Record Types

Two new Record Types are needed.

Picklist values can be set per Record type. For example, only allow approval status to be certain values on each record type. Alternatively the approval status field can be made to be read only.
 

3. Create a Flow

You will need a flow with decision logic to choose which Record Type to use.

Setup | Process Automation | Flows | New Flow

1. Object = Quote
2. Configure Trigger = A record is created or updated
3. Condition Requirements = Any Condition Is Met (OR)
4. Setup 3 Conditions.
   1. ApprovalStatus__c = Recalled
   2. ApprovalStatus__c = Rejected
   3. ApprovalStatus__c = Pending
5. Click Done
6. Add Decision Element
   1. Fill in New Outcome Label
   2. Condition Requirements to Execute Outcome = All Conditions Are Met (AND)
   3. Resource = {!$Record.ApprovalStatus__c} "You can get to this by going to SBQQ__Quote__c and choosing Approval Status"
   4. Change Label on Default Outcome
   5. Click Done
7. Add Update Element under Default Outcome
   1. How to Find Records to Update and Set Their Values = Use the quote record that triggered the flow
   2. Condition Requirements to Update Record = None-Always Update Record
   3. Field = RecordTypeID and Value = The Id for the Record Type that is using the page layout with the Submit for Approval button.
   4. Click Done
8. Add Update Element under New Outcome
   1. How to Find Records to Update and Set Their Values = Use the quote record that triggered the flow
   2. Condition Requirements to Update Record = None-Always Update Record
   3. Field = RecordTypeID and Value = The Id for the Record Type that is using the page layout without the Submit for Approval button.
   4. Click Done
9. Click Save
10. Click Activate
11. Test

Existing quotes will not be updated to reflect the correct record type. This can be done manually or you can mass update record types with Data Loader.
