When importing custom objects, solutions, or person accounts, you can use external IDs to prevent duplicate records from being created as a result of the import operation. An external ID is a custom field that has the “External ID” attribute, meaning that it contains unique record identifiers from a system outside of Salesforce. When you sel…[Read more]

It’s per each call of execute() in the batch, so for each “batch”, you can call up to 10 HTTP callouts.

If the callout can handle multiple records at a time, do so, and batch up to 10 callouts per batch, otherwise, set the batch scope to 1, so each apex batch handles one record at a time.

A fiscal year or financial year is a period of time used to calculate annual (yearly) financial statements in businesses and other organizations. The system administrator can set the fiscal year for your organization. The fiscal year settings are used to report on the fiscal year timeline.

External ID fields are indexed, so selective filters on th…[Read more]

Salesforce Record data has three stages of deletion. Data is recovered depending on the stage it is in.

Stage 1 – Deleted to Recycle Bin – Data in this stage can be recovered from the Recycle Bin. This can also be referred to as soft-deleted.

To find and restore records in the Recycle Bin:

On the left side of the homepage in CRM, click on…[Read more]

You can use master-detail relationships to model many-to-many relationships between any two objects. A many-to-many relationship allows each record of one object to be linked to multiple records from another object and vice versa. For example, you create a custom object called “Bug” that relates to the standard case object such that a bug could…[Read more]

Use the System.RestRequest class to access and pass request data in a RESTful Apex method. An Apex RESTful Web service method is defined using one of the REST annotations. For more information about Apex RESTful Web service, see Exposing Apex Classes as REST Web Services.

Bulk API is based on REST principles and is optimized for loading or deleting large sets of data. You can use it to query, queryAll, insert, update, upsert, or delete many records asynchronously by submitting batches. Salesforce processes batches in the background.

SOAP API, in contrast, is optimized for real-time client applications that update…[Read more]

In Salesforce a ‘callout’ is any https call that accesses an external URL — some other webservice or website. A ‘callin’ would be the opposite — some external web service or application using the Salesforce API to access Salesforce data.

Static resources allow you to upload content that you can reference in a Visualforce page, including archives (such as .zip and .jar files), images, style sheets, JavaScript, and other files.

Using a static resource is preferable to uploading a file to the Documents tab because:

You can package a collection of related files into a directory…[Read more]

Hi,

The limit of custom objects in Enterprise Edition is 200 .

Global publisher layouts determine the global actions that appear in the various Salesforce interfaces. In Salesforce Classic and Lightning Experience, these layouts customize the actions on global pages (like the Home page) and on the Chatter page. Lightning Experience also uses these layouts to populate the Global Actions menu. And in the…[Read more]

SOQL has very limited aliasing support. We can alias the table, e.g. SELECT a.name FROM Account a, but that’s of very little use. In most contexts we cannot alias fields.

The one exception is for queries that use aggregations, like SELECT COUNT(Id) recordCount FROM Account allows us to alias the result of the aggregation from it’s default expr0…[Read more]

callouts cannot be made from apex triggers as that restricts database transaction until the callout is completed and the time limit for this is up to 120 seconds.

The only way to execute a callout from a trigger is to run it asynchronously and this can be achieved by executing a method with the @future method.
