    The parameter types that the Microsoft BizTalk Adapter 3.0 for mySAP Business Suite supports are governed by the:

    • ABAP data types that SAP supports

    • Database data types that SAP supports

    This section presents a mapping between the ABAP and database data types, and their corresponding .NET and XML schema types.

    Cc185537.note(en-US,BTS.10).gifNote
    The information in this section applies to RFCs, tRFCs, and BAPIs. SAP data types are always represented as strings (xsd:string) in IDOCs. This is to support the BizTalk Server flat file parser.
    Supported ABAP Data Types

    The Microsoft BizTalk Adapter 3.0 for mySAP Business Suite supports safe typing for some ABAP data types. When safe typing is enabled, these data types are represented as strings. You configure safe typing by setting the EnableSafeTyping binding property. Safe typing is disabled by default. For more information about the SAP adapter binding properties, see Working with BizTalk Adapter 3.0 for mySAP Business Suite Binding Properties.

    The following table shows how the ABAP data types are surfaced when safe typing is not enabled. (EnableSafeTyping is false). Data types that are surfaced differently when safe typing is enabled are marked with an asterisk (*).

    Internally, the adapter deserializes the value into a DateTime object. It then invokes theDateTime.ToUniversalTime method to convert the value of this object to UTC. Finally the date component (DateTime.Date) is used to create the value that is sent to the SAP system. The SAP system treats this date value as local time.

    You should specify date values as UTC to avoid conversion.

    • For xsd:dateTime, the following pattern is recommended: "(dddd-dd-dd)T(00:00:00)(.*)Z".

    • For DateTime objects set DateTime.Kind to DateTimeKind.Utc.

    T (Time: HHMMSS)*

    Internally, the adapter deserializes the value into a DateTime object. It then invokes theDateTime.ToUniversalTime method to convert the value of this object to UTC. Finally the time component (DateTime.Time) is used to create the value that is sent to the SAP system. The SAP system treats this time value as local time.

    You should specify time values as UTC to avoid conversion.

    • For xsd:dateTime, the following pattern is recommended: "(0001-01-01)T(dd:dd:dd)(.*)".

    • For DateTime objects set DateTime.Kind to DateTimeKind.Utc.

    For example, if your local time is 9:15 am, express this as "(001-01-01)T(09:15:00)Z"

    Safe Typing Enabled

    The following table shows the ABAP data types that are surfaced differently when safe typing is enabled (the EnableSafeTyping binding property is true).

     

    ABAP Data TypeRFC TypeXSD type.NET typeFormat string

    D (Date: YYYYMMDD)

    RFC_DATE

    xsd:string

    String

    SAP date format: YYYYMMDD.

    Characters are allowed for date digits, so the value is essentially an eight character string

    T (Time: HHMMSS)

    RFC_TIME

    xsd:string

    String

    SAP time format: HHMMSS.

    Characters are allowed for time digits, so the value is essentially a six character string

    N (Numeric string)

    RFC_NUM

    xsd:string

    String

    An n character string; where n = length of the numc field.

    ABAP data types that are not in this table are surfaced in the same way as when safe typing is not enabled.

    Support for Date and Time Fields

    When safe typing is not enabled, ABAP Date (D) and Time (T) types are surfaced as xsd:dateTime; however, the pattern facet surfaced for the Date and Time types is different.

    • The pattern facet for Date is: (dddd-dd-dd)T(00:00:00)(.*)

      For example, July 7, 2007 (2007-07-07) is represented as: 

      (2007-07-07)T(00:00:00).

    • The pattern facet for Time is: (0001-01-01)T(dd:dd:dd)(.*)

      For example, 18:30:30 (6:30 pm and 30 seconds) is represented as: 

      (0001-01-01)T(18:30:30).

    How does the Adapter Represent Minimum and Maximum Time Values on Inbound Messages (from SAP)?

    The SAP adapter uses the following guidelines when it receives time values from the SAP system:

    • The adapter treats 000000 (hhmmss) and 240000 (hhmmss) as 0 hours, 0 mins, and 0 seconds.

    Supported Database Data Types

    The way in which the Microsoft BizTalk Adapter 3.0 for mySAP Business Suite surfaces database data types also depends on whether safe typing is enabled. The following table shows how the adapter surfaces database data types when safe typing is not enabled (the EnableSafeTyping binding property is false). Data types that are surfaced differently when safe typing is enabled are marked with an asterisk (*).

    The SAP adapter rounds off the decimal values based on the definition of the DECIMAL parameter. For example, if a DECIMAL parameter can accept up to five digits after the decimal point, a value such as 4.000028 is rounded off to 4.00003.
