start-elements-lowercase

Rule Details

According to our naming conventions, to easily distinguish entity names from element names we recommend starting elements with a lowercase letter, which this rule ensures.

Examples

✅   Correct example

In the following example, the rule is satisfied because the element name title starts with a lowercase letter:

db/schema.cds

namespace sap.capire.bookshop;

entity Books {
  key ID : Integer;
  @mandatory title  : localized String(111);
}
