Second level child rows not getting updated by a web service call

Question

hi,
I have a web service that takes a Header object (type: Header). Below is the part of the WS schema:
<xsd:complexType name="Header">
<xsd:sequence>
<xsd:element name="Segment1" type="xsd:string" minOccurs="0"/>
<xsd:element name="SoldtoBuId" type="xsd:long" minOccurs="0" nillable="true"/>
<xsd:element name="ChangeAcceptedFlag" type="xsd:string" minOccurs="0" nillable="true"/>
<xsd:element name="Lines" type="Line" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Line">
<xsd:sequence>
<xsd:element name="LineNum" type="xsd:long" minOccurs="0" nillable="true"/>
<xsd:element name="ChangeAcceptedFlag" type="xsd:string" minOccurs="0" nillable="true"/>
<xsd:element name="Schedules" type="Schedule" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Schedule">
<xsd:sequence>
<xsd:element name="ScheduleNum" type="xsd:long" minOccurs="0" nillable="true"/>
<xsd:element name="ChangeAcceptedFlag" type="xsd:string" minOccurs="0" nillable="true"/>
</xsd:sequence>
</xsd:complexType>
So a header element can have one or more lines and a line can have one or more schedules.
Each of those entities have are based on tables (via EO & VO).
Header table has primary key of HeaderId,
Line table has primary key of LineId,
Schedule table has primary key of ScheduleId,
These primary keys are not part of the schema however they are there in the VOs.
A Header can be uniquely identified by combination of Segment1 & SoldToBu which are part of the header element and they are added as a Altkey on the HeaderVO,
For a given header a line can be uniquely identified by the LineNum which is added as Alt key on LineVo,
And for a given line a schedule can be uniquely identified by the ScheduleNum which is added as Alt key on ScheduleVo.
LineVO is added to the Service AM under HeaderVO via a ViewLink and similarly ScheduleVO is added below LineVO via viewLink.
When I invoke the webservice the service identifies the header and line rows and updates them. It also identifies schedule rows but they are not getting updated.
Any Idea what the prob. can be.
Thanks in Advance!!

Hi Juhani,
Do you try to execute the Web Service with SoapUI or XMLSpy??
I think that is not a problem with abap side, but with java. I recomend to you use the following prefix in function modules:
IMPORTING: I_
EXPORTING: E_
TABLES: T_
