HI Karthick,
Thanks for your reply.
while exporting the application it is running properly on NWDS platform as well in Eclipse platform but not in mi client.
i am sure that,
<b>MCD Name = Application Name = War file which is MDK_TUTORIAL_SYNC</b>
Below is my Meta XML file:
<b><?xml version="1.0" encoding="utf-8" ?>
- <MeRepApplication schemaVersion="1.1" id="MDK_TUTORIAL_SYNC" version="250901">
  <Property name="CLIENT.BUILDNUMBER" />
  <Property name="C_APPLRESOLVE" />
  <Property name="DATA_VISIBLE_SHARED" />
  <Property name="EN">LANGUAGE</Property>
  <Property name="E_APPLRESOLVE" />
  <Property name="FACADE_C_CLIENT">X</Property>
  <Property name="FACADE_E_CLIENT">X</Property>
  <Property name="HOMEPAGE.INVISIBLE" />
  <Property name="INITVALUE" />
  <Property name="RUNTIME">JSP</Property>
  <Property name="TYPE">APPLICATION</Property>
- <SyncBO id="ZNWW_EXM01" version="2" type="download" allowCreate="false" allowModify="false" allowDelete="false" reqDirectSync="false">
- <TopStructure name="TOP">
- <Field name="SYNC_KEY" type="N" length="10" decimalLength="0" signed="false" isKey="true" isIndex="true">
  <Input type="create">false</Input>
  <Input type="modify">false</Input>
  </Field>
- <Field name="LAND_TEXT" type="C" length="50" decimalLength="0" signed="false" isKey="false" isIndex="false">
  <Input type="create">false</Input>
  <Input type="modify">false</Input>
  </Field>
  </TopStructure>
  </SyncBO>
  </MeRepApplication></b>
reffer the above xml file and please find if  i miss any fields.
