We often get requests to convert a Lookup field to a Master-Detail relationship in Salesforce. There are several reasons why this might be necessary, but the most common is that the data needs to be reportable. In this article, we’ll explore whether or not it’s possible to convert a Lookup field to a Master-Detail relationship in Salesforce.
- In Salesforce, open the object you want to convert to a master detail relationship
- Click the New button, and select Master Detail Relationship from the drop-down list
- Enter a relationship name and description, then select the parent object from the drop-down list
- Select a field to use as the unique identifier for the child records (the foreign key)
- This field is required for master detail relationships
- Click Save & New, then click Deploy to Users on the next page to make your changes available to users immediately, or click Save for Later if you don’t want to deploy your changes yet
Can We Convert Lookup into Master Detail?
A Lookup relationship field on a standard object can be converted to a Master-Detail relationship field. The Master Detail relationship will enforce referential integrity between the two objects, meaning that you cannot delete the record on the master object if there are any related records on the detail object. To convert a Lookup relationship to a Master-Detail relationship, follow these steps:
1. From Setup, enter Objects in the Quick Find box, then select Objects. 2. Click New in the Standard Objects related list. 3. Enter Object Name and Label as desired (e.g., MyObject__c).
Then click Next. 4. On the Page Layout assignment step, leave Create New Layout unchecked and click Next twice (through Sharing Model), then click Save & Finish. This creates your new custom object with no page layout assigned yet—we’ll do that next step using Lightning App Builder rather than working directly in Salesforce Classic due to some known issues converting lookup fields to master-detail ones later if you don’t use Lightning App Builder for this part of the process.
. 5 Now that we have our new custom object created (called “MyObject__c” in our example), let’s add it to our existing page layout so we can convert our lookup field into a master-detail one: 6 In Lightning Experience, go to Setup by clicking on the gear icon in the top right corner of your screen and selecting “Setup” from dropdown menu.
. 7 In Lightning Experience setup search for “Lightning App Builder” and select it from results OR navigate to “Lightning App Builder” by following path: Lightening: Build | Apps | Lightning App Builder..
8 Select your app from drop down menu OR create new app.. 9 Drag and drop newly created custom object (MyObject__c) into left hand side panel called “Custom Components” 10 Publish changes 11 Now that we have added our new custom object into page layout via Lightning App Builder, we can edit page layout directly within Salesforce Classic without fear of losing data or having problems converting our lookup field into a master-detail one later on.
In Which Scenario Can the Master Detail Relationship Be Converted into Lookup Relationship?
When should you consider converting a Master-Detail relationship to a Lookup relationship?
There are certain reasons why you might want to convert a Master-Detail relationship to a Lookup relationship. One reason is if your org has reached the limit of relationships (25 for Professional Edition, 200 for Enterprise, Unlimited, and Performance Edition).
If you need to add an additional object that relates to the original master detail object, but you have already hit the limit for number of relationships, then you will need to change one of the existing relationships to lookup so that you can create the new one. Another reason might be if you find yourself in a situation where having too many Detail objects is causing performance issues. In this case, consolidating some of those Detail objects into one object by changing their relationships from Master-Detail to Lookup would improve performance.
Finally, another often overlooked reason is security. By default, all users have read and write access to records associated with any Master-Detail relationship on an object they have access to. However, withLookup relationshipsyou can restrict read/write access at the field level by using Field Level Security.
How Do I Create a Lookup And Master Detail Relationship in Salesforce?
Salesforce gives you the ability to create powerful relationships between your data using Lookup and Master-Detail relationships. Creating these relationships can help keep your data organized, making it easier to find and report on the information you need.
Lookup relationships allow you to link two objects together, such as linking a Contact to an Account.
This relationship is created by adding a lookup field to one of the objects. The lookup field stores the ID of the record from the other object that it is linked to. You can then use this relationship to pull information from both objects into a single report or view.
Master-detail relationships are similar to lookup relationships, but are even more closely linked. A master-detail relationship links a child object to a parent object. This relationship is created by adding a master-detail field to the child object.
The master-detail field stores the ID of the parent record, linking the two objects together. Creating either type of relationship is easy using Salesforce’s point-and-click interface. Simply navigate to the fields page for the object you want to add the relationship too and click “Add Field”.
Then select either “Lookup Relationship” or “Master Detail Relationship” from the field type options depending on which type of relationship you want to create. After giving your new field a label, select which object you want it be related too and click save!
Can We Create Both Master Detail Relationship And Lookup Relationship at a Time?
A lookup relationship is an optional relationship in which the foreign key can be either null or populated. A master-detail relationship is a required relationship in which the foreign key must always be populated. You cannot create both a master-detail and lookup relationship on the same field.

Lookup And Master-Detail Relationship in Salesforce Example
Salesforce Lookup and Master-Detail Relationship:
In Salesforce, a lookup relationship is a field that links one object to another. The field can be found on the “detail” object and allows you to look up or reference data from the “master” object.
A master-detail relationship in Salesforce is when two objects are linked together by a parent-child relationship. The child object is known as the detail object, while the parent object is known as the master object. This type of relationship gives users the ability to roll up data from detail records into a single record on the master object.
For example, let’s say you have an “Accounts” object and a “Contacts” object. Each account has many contacts associated with it, but each contact can only be associated with one account. In this case, there would be a lookup field on the “Contacts” object that points to the “Accounts” object.
This lookup field would be used to specify which account a particular contact belongs to. A master-detail relationship between these two objects would allow you to roll up data from all of the contacts associated with an account onto the account record itself. For example, you could create a formula field that displays the number of contacts associated with an account or even create a report that shows all of the contacts for all accounts in your org!
Master-Detail Relationship Salesforce
A Master-Detail relationship in Salesforce is a type of relationship between two objects where one object is the “master” and the other is the “detail.” This relationship can be used to relate records in one object to records in another object. The master-detail relationship is used to create a link between two records.
When you create a Master-Detail relationship, a new field (Master-Detail Relationship Field) is automatically created on the detail object. This field links the detail record back to its parent master record. There are several benefits to using a Master-Detail relationship:
· You can use roll-up summary fields to calculate values on the parent record from related child records. For example, you could create a roll-up summary field on an opportunity that calculates the sum of all associated line items. · You can enforce data integrity by making the child record required when creating or editing the parent record.
This ensures that every parent record has at least one child record. · You can give users different levels of access to parent and child records using security settings. For example, you could make all opportunities viewable by all users, but restrict access to line items so that only certain users can see them.
What are Two Considerations for Converting a Lookup to a Master-Detail Relationship
When you are working with data in Salesforce, it is important to understand the difference between a lookup relationship and a master-detail relationship. A lookup relationship is simply a reference from one object to another. A master-detail relationship is a more complex relationship that includes a link from one object to another, as well as some additional information about the linked objects.
There are two considerations that you should keep in mind when you are converting a lookup relationship to a master-detail relationship: 1. The first consideration is whether or not you need the extra information that is included in a master-detail relationship. If you do not need this information, then there is no reason to convert the lookup relationship to a master-detail relationship.
2. The second consideration is whether or not your data will be consistent if you convert the lookup relationships to master-detail relationships. This can be tricky to assess, so it is important to work with your Salesforce administrator before making any changes.
Can We Create Master Detail Relationship on Existing Records?
In Salesforce, a Master-Detail relationship is used to relate two objects together. The “Master” object is the primary object while the “Detail” object is the secondary or child object. This relationship creates a link between the two objects so that data from the child object can be pulled into reports and views on the parent object.
It is possible to create a Master-Detail relationship on existing records. To do this, you will need to first create a custom field on the Detail object that will hold the ID of the record from the Master object. Once you have created this field, you can then go into each Detail record and populate it with the ID of its corresponding Master record.
After doing this for all records, you will then need to create a new lookup field on the Detail object that points to the Master object. This lookup field will allow you to establish the relationship between records and pull data accordingly.
Salesforce provides many features to its users and one of these is the ability to convert a lookup field to a master-detail relationship. This can be done by following a few simple steps:
1. Go to Setup in Salesforce and type “Convert Lookups to Master-Detail” into the Quick Find box.
Click on the resulting link. 2. Select the object that you want to convert from the list of available objects. 3. Choose the lookup field that you want to convert into a master-detail relationship and click Save.
