Syntax error in function call through EF6

Question

I'm trying to call a function from an EF6 query but it seems the compiled statement has a syntax error and the DBMS bails out with "ORA-00933: SQL-Befehl wurde nicht korrekt beendet" (SQL statement ends with an inappropriate clause). As far as I understand the Oracle .NET provider compiles E-SQL to SQL for Oracle in the first place, so how come the statement is malformed?
Here's what EF logs for this particular statement:
Opened connection at 26.01.2015 09:46:14 +01:00
SELECT
"Extent1"."Z_AS" AS "Z_AS"
FROM "DEMO_VIVPFLEGEDOKU"."FN_GETASSESMENTCHILDS_AUSMENGE"(:STRFILTER) "Extent1"
-- STRFILTER: '1' (Type = Object)
-- Executing at 26.01.2015 09:46:14 +01:00
-- Failed in 79 ms with error: ORA-00933: SQL-Befehl wurde nicht korrekt beendet
Closed connection at 26.01.2015 09:46:14 +01:00
This is with VS 2013 Update 4, ODP.NET (ODTwithODAC121021 package) and Oracle 12c DBMS.
The function is defined as
create or replace function fn_GetAssesmentChilds_AusMenge(strFilter varchar2)
RETURN TTabOneNumber pipelined
is
IndexEing PLS_INTEGER;
IndexZ_Aus PLS_INTEGER;
Cursor CursorEing is select column_value from TABLE(fn_splitstring( strFilter ));
Cursor CursorAssessCh is select column_value from TABLE(fn_GetAssesmentChilds_AusInt(IndexEing));
BEGIN
open CursorEing;
fetch CursorEing into IndexEing;
while CursorEing%found
loop
open CursorAssessCh;
fetch CursorAssessCh into IndexZ_Aus;
while CursorAssessCh%found
loop
pipe row (IndexZ_Aus);
fetch CursorAssessCh into IndexZ_Aus;
end loop;
close CursorAssessCh;
fetch CursorEing into IndexEing;
end loop;
close CursorEing;
END fn_GetAssesmentChilds_AusMenge;
Here's the sample code for what I'm trying to achieve:
using System;
using System.Linq;
namespace ConsoleApplication17
   class Program
      static void Main(string[] args)
         using (var db = new Entities())
            var ids = db.GetAssessmentIds("1")
                  .Select(r => r.Z_AS);
            Console.WriteLine(string.Join(",", ids));
For the sake of completeness, here are the relevant parts from the EDMX:
SSDL
        <Function Name="FN_GETASSESMENTCHILDS_AUSMENGE" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="true" ParameterTypeSemantics="AllowImplicitConversion" Schema="DEMO_VIVPFLEGEDOKU">
          <Parameter Name="STRFILTER" Type="varchar2" Mode="In" />
           <ReturnType>
              <CollectionType>
                 <RowType>
                    <Property Name="Z_AS" Type="number" Precision="10" Scale="0" />
                 </RowType>
              </CollectionType>
           </ReturnType>
        </Function>
CSDL
          <FunctionImport Name="GetAssessmentIds" ReturnType="Collection(CareDocumentation.fn_GetAssesmentChilds_AusMenge_Result)" IsComposable="true">
             <Parameter Name="STRFILTER" Mode="In" Type="String" />
          </FunctionImport>
MSL
          <FunctionImportMapping FunctionImportName="GetAssessmentIds" FunctionName="CareDocumentation.Store.FN_GETASSESMENTCHILDS_AUSMENGE">
             <ResultMapping>
                <ComplexTypeMapping TypeName="CareDocumentation.fn_GetAssesmentChilds_AusMenge_Result">
                   <ScalarProperty Name="Z_AS" ColumnName="Z_AS" />
                </ComplexTypeMapping>
             </ResultMapping>
          </FunctionImportMapping>
Return type:
         <ComplexType Name="fn_GetAssesmentChilds_AusMenge_Result">
            <Property Name="Z_AS" Type="Int32" />
         </ComplexType>
Any ideas as to what is going on here?

Hello Thanvi
It seems that you need to apply the OSS note 1041283:
FUNCTION cacs_bupa_pai_special_cacsb1.
*"*"Lokale Schnittstelle:
  DATA: lt_but0bk TYPE TABLE OF but0bk WITH HEADER LINE.
  CALL FUNCTION 'BUP_BUPA_BUT0BK_GET'
       TABLES
            t_but0bk = lt_but0bk.
* einmal vorhanden -> nehmen; nicht vorhanden -> Feld muss leer sein
* mehrmals vorhanden -> Mussfeld
  READ TABLE lt_but0bk INDEX 2.
  IF sy-subrc NE 0.
*    READ TABLE lt_but0bk.          "NOTE 1041283   " <<<<<<<<<
     READ TABLE lt_but0bk FROM lt_but0bk.            " <<<<<<<<<
    IF sy-subrc = 0.
      cacs_s_bupaw-bank_id = lt_but0bk-bkvid.
    ENDIF.
  ELSE.
