X12 Data Types
EdiFabric supports the following data element types.
Numeric
Data element can include digits only.
Numeric data with implied decimal. If the decimal part is included, n shows the number of digits to the right of the implied decimal.
Leading zeros are suppressed unless needed to satisfy the minimum length of the element. If the value is negative, include a minus sign, which does not count toward the length.)
N and N0 are equivalent (it is not necessary to include the zero). This means the implied decimal is at the end of the number.
N1 means there is one digit to the right of the implied decimal. Example: The element contains the value -123, which is to be interpreted as -12.3.
N2 means there are two digits to the right of the implied decimal. Example: The element contains the value -123, which is to be interpreted as -1.23.
The DOM C# class representing numeric X12 data type is:
[Serializable()]
public class X12_N0
{
}
Decimal
Data element can include decimal point and digits only. Decimal point is optional for integers.
The number after R shows the maximum number of digits to the right of the decimal. R0 means there should be no digits to the right of the decimal.
Example: The element contains the value 150.25 and the type is R. The value being represented is also 150.25.
Example: The element contains the value 150.23 but the type is R1. The value being represented would be 150.2
Signs and decimal points do not count toward length.
The DOM C# class representing decimal X12 data type is:
[Serializable()]
public class X12_R
{
}
Alphanumeric
Data element can include any letters, digits, special characters, and control characters.
X12 notation combines the type and length as in the following examples:
an5 exactly 5 alphanumeric characters
an..5 up to 5 alphanumeric characters.
The DOM C# class representing alphanumeric X12 data type is:
[Serializable()]
public class X12_AN
{
}
Date
Date, in YYMMDD or CCYYMMDD format. CC is century.
The DOM C# class representing date X12 data type is:
[Serializable()]
public class X12_DT
{
}
Time
Time, in 24-hour clock time as follows: HHMM or HHMMSS.
The DOM C# class representing time X12 data type is:
[Serializable()]
public class X12_TM
{
}
DTP segments
Date, in CCYYMMDD or CCYYMMDD-CCYYMMDD-CCYYMMDD format. CC is century.
When a DTP segment is encountered the validator will validate all data elements with code 1251 only if there is a preceding data element with code 1250 and value D8 or RD8.
X12 Data Types Validation
By default alphabetic or alphanumeric strings are not validated for invalid characters. To enable this type of validation an implementation of a SyntxSet must be passed to either the IsValid method of EdiMessage or the X12Reader constructor (when using splitting only).
The following syntax set implementations are available:
Basic
Valid characters are:
ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!&()*+,-./:;?= '""
MessageErrorContext result; var validationResult = msg.IsValid(out result,
new ValidationSettings { SyntaxSet = new Basic()});
Extended
Valid characters are:
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!&()*+,-./:;?= '""%@[]_{}\|<>~#$
MessageErrorContext result; var validationResult = msg.IsValid(out result,
new ValidationSettings { SyntaxSet = new Extended()});
