INCLUDES

Use

INCLUDES(multiselect_picklist_field, text_literal) and replace multiselect_picklist_field with the merge field name for the multi-select picklist; and replace text_literal with the multi-select picklist value you want to match in quotes.

Tips

• The text_literal expression must be of type text and enclosed in quotes. It cannot be a merge field or the result of a function.
• Salesforce returns an error if any of the following occurs:
  • You do not provide a text_literal expression.
  • You provide an empty text_literal expression, such as "" or " ".
• Use ISBLANK to determine if a multi-select picklist field is empty.
• Use the PRIORVALUE function inside the INCLUDES function to check if the previous value of a multi-select picklist field included a specific value. For example:

  INCLUDES(
     PRIORVALUE(multiselect_picklist_field),
  text_literal
  )
