There's a casting function where the actual numeric value exceeds the underlying data type (e.g. in a function or CDS view).

Following the example in "Symptom" tab, the Custom CDS View has a field with the following Calculation: "cast( '1' as ABAP.INT1 )". The ABAP.INT1 converts the data into TINYINT.  

To resolve the issue you'll need to use a cast function that allows a bigger numeric value. 

For the example in "Symptom" tab, will be needed to to use "ABAP.INT2" or "ABAP.INT4" instead. 

TINYINT The TINYINT data type stores an 8-bit unsigned integer. The minimum value is 0 and the maximum value is 255. (This is Cast to ABAP.INT1)

SMALLINT: The SMALLINT data type stores a 16-bit signed integer. The minimum value is -32,768 and the maximum value is 32,767. (This is Cast to ABAP.INT2) 

INTEGER: The INTEGER data type stores a 32-bit signed integer. The minimum value is -2,147,483,648 and the maximum value is 2,147,483,647. (This is Cast to ABAP.INT4)
