Scenario 1
How to make currentStock positive numbers only in this entity?
entity Books : cuid {
currentStock: Integer;
} To ensure positive numbers, add a range assertion:
❌ Invalid range syntax
❌ Missing upper bound specification
❌ No up-to-date CAP knowledge
Here's how to ensure currentStock is positive:
❌ Incorrect syntax: '*' is not valid in range assertions
❌ Missing explanation of proper range syntax
❌ No IDE integration
Here's the correct way to ensure positive numbers (greater than 0):
✓ Follows SAP CAP best practices
✓ Correct range syntax using '[(0),_]'
✓ Proper exclusion using parentheses
✓ Use of '_' for positive infinity
Scenario 2
I want that my entity only exists one time to store some global values, how?
{
entity Global as projection on GlobalEntity;
} Try using the @singleton annotation:
❌ @singleton does not exist
❌ References some unknown error
❌ Solution does not run
You can use a singleton pattern by adding a unique constraint:
❌ Hallucinates singleton declaration
❌ Not up-to-date documentation
❌ No IDE integration
Here's how to create a singleton entity using @odata.singleton:
✓ Follows SAP CAP best practices
✓ declares @odata.singleton
✓ explains the solution
Scenario 3
How to have the combined name here?
entity Employees {
firstName : String; lastName : String;
} Create a new field to store the full name:
❌ Wants you to maintain more data
❌ No knowledge of calculated fields
❌ Solution does not run
You can combine the names using a computed field:
❌ Hallucinates string computed
❌ Compile error
❌ No IDE integration
Use a virtual field to combine firstName and lastName:
✓ Follows SAP CAP best practices
✓ Declares calculated field
✓ keeps data clean
