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 the user 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 will check if the selected ABAP type is compatible with EDM type. In case of non-compatibility an error message will be 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:

Table 1: EDM Types and Facets
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

Table 2: Proposed ABAP Types
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 any mismatch then a warning message is displayed.
