EDM Type Vs ABAP Type Validation
Details about validation for mismatch between the property’s EDM type and ABAP type.
Introduction
In Service Builder, for a property, as you can set an EDM
type as well as an internal ABAP type there is a need to validate if there is a mismatch
between the property’s EDM type and ABAP type. The validation is triggered as part of
the consistency check in Service Builder. For example, if you import a model with a type
EDM.String and wanted to map it with the ABAP type, you have to provide an internal
type. This functionality checks whether the selected ABAP type is compatible with EDM
type. In case of non-compatibility an error message is displayed. For more information
about the validation check for mappings between EDM types and ABAP types, see
Mappings and the ABAP Type Editor.
EDM Types and Facets
The following are the EDM types their facets and the related ABAP types:
| EDM Type | Facets |
|---|---|
| Binary | Nullable Default, MaxLength, FixedLength |
| Boolean | Nullable, Default, NA |
| DateTime | Nullable, Default, Precision |
| Time | Nullable, Default, Precision |
| DateTimeOffset | Nullable, Default, Precision |
| Decimal | Nullable, Default, Precision, Scale |
| Single | Nullable, Default |
| Guid | Nullable, Default |
| Double | Nullable, Default |
| SByte | Nullable, Default |
| Int16 | Nullable, Default |
| Int32 | Nullable, Default |
| Int64 | Nullable, Default |
| String | Nullable, Default, Unicode, FixedLength, MaxLength |
| EDM Type | Condition | Proposed ABAP Type |
|---|---|---|
| Binary | Max Length (M) is 0 < M <= 65535 | Type X LENGTH M |
| MaxLength (M) is M > 65535 | Invalid | |
| MaxLength (M) is =0 | XSTRING | |
| Boolean | C LENGTH 1 | |
| DateTime | Precision (P) is 0 | TIMESTAMP |
| Precision (P) is 0 | TIMESTAMPL | |
| Precision (P) is 7 | TIMESTAMPL | |
| Precision (P) >7 | Invalid | |
| SByte | INT2 | |
| Byte | INT1 | |
| String | Max Length (M) is 0 < M <= 65535 | Type C LENGTH M |
| MaxLength (M) is M > 65535 | Invalid | |
| MaxLength (M) is =0 | STRING |
Note The maximum length facets are compared with the length of the ABAP
internal type. Incase of mismatch a warning message is displayed.
