Help needed on mapping information for AT701 element in EDI X12 214 Transportation type (X12_00401_214 schema)

Question

Hi all,
As per the EDI defined standard schema, AT701 element takes the following Enumeration values.
<xs:element minOccurs="0" name="AT701" type="X12_ID_1650">
<xs:annotation>
<xs:appinfo>
<b:fieldInfo notes="Shipment Status Code_1650" />
</xs:appinfo>
</xs:annotation>
</xs:element>
<xs:simpleType name="X12_ID_1650">
<xs:restriction base="xs:string">
<xs:enumeration value="A3" />
<xs:enumeration value="A7" />
<xs:enumeration value="A9" />
<xs:enumeration value="AF" />
<xs:enumeration value="AG" />
<xs:enumeration value="AH" />
<xs:enumeration value="AI" />
<xs:enumeration value="AJ" />
<xs:enumeration value="AM" />
<xs:enumeration value="AN" />
<xs:enumeration value="AP" />
<xs:enumeration value="AR" />
<xs:enumeration value="AV" />
<xs:enumeration value="B6" />
<xs:enumeration value="BA" />
<xs:enumeration value="BC" />
<xs:enumeration value="C1" />
<xs:enumeration value="CA" />
<xs:enumeration value="CD" />
<xs:enumeration value="CL" />
<xs:enumeration value="CP" />
<xs:enumeration value="D1" />
<xs:enumeration value="I1" />
<xs:enumeration value="J1" />
<xs:enumeration value="K1" />
<xs:enumeration value="L1" />
<xs:enumeration value="OA" />
<xs:enumeration value="OO" />
<xs:enumeration value="P1" />
<xs:enumeration value="PR" />
<xs:enumeration value="R1" />
<xs:enumeration value="RL" />
<xs:enumeration value="S1" />
<xs:enumeration value="SD" />
<xs:enumeration value="X1" />
<xs:enumeration value="X2" />
<xs:enumeration value="X3" />
<xs:enumeration value="X4" />
<xs:enumeration value="X5" />
<xs:enumeration value="X6" />
<xs:enumeration value="X8" />
<xs:enumeration value="XB" />
</xs:restriction>
</xs:simpleType>
Now, in my sample input file I am having a column "MileStone", and for example: If I have
"Picked Up Date" in that column, I need to pass "A3" as the value for
AT701 element as per the above code snippets. 
Please let me know how to map the "Milestone to "AT701" element.
If I straight away map those two fields, I am getting the below error : 
error btm1046: Output validation error: The 'AT701' element is invalid - The value 'MileStone_0' is invalid according to its datatype 'http://schemas.microsoft.com/BizTalk/EDI/X12/2006:X12_ID_1650' - The Enumeration constraint failed.
So, please guide me on how to map the above fields using the functoids. 
Thanks in Advance..

Hi Anand,
You can try
Value Mapping functiod along with Logical Equal functiod for this requirement.
Connect the element “MileStone”
to the Logical Equal functiod as the it’s first parameter. And add “Picked Up Date”
as the second parameter.
Connect output of the Logical Equal functiod as the first parameter to the Value Mapping functiod and “A3"
as the second parameter.
Connect the output of
Value Mapping functiod “AT701”
element.
This maps the value “A3”
to the element “AT701”, if the value of “MileStone” element is
“Picked Up Date”
