Hi,Anuradha
There is a new find out. I can access the task with the preview link of the htm file.
And I open up the attached htm file and find out the following text:
<html style="font-family:sans-serif"> <head>
<meta http-equiv="Refresh" content="3; URL=http://erpdev.wingtech.com:8000/sap/bc/nwbc//~canvas;window=app/wda/cprojects_fpm/?sap-client=300&sap-client=300&STARTVIEW=Tasks&OBJ_EVENT=TTOC81F66B8A8F51ED3BEDB4083DBDBCE57C81F66B8A8F51ED3BEDB4083DBCD6E57DPO&sap-sessioncmd=open&sap-wd-configid=CPROJECTS_FPM&sap-language=ZH">
</head> <body>
<a href="http://erpdev.wingtech.com:8000/sap/bc/nwbc//~canvas;window=app/wda/cprojects_fpm/?sap-client=300&sap-client=300&STARTVIEW=Tasks&OBJ_EVENT=TTOC81F66B8A8F51ED3BEDB4083DBDBCE57C81F66B8A8F51ED3BEDB4083DBCD6E57DPO&sap-sessioncmd=open&sap-wd-configid=CPROJECTS_FPM&sap-language=ZH">http://erpdev.wingtech.com:8000/sap/bc/nwbc//~canvas;window=app/wda/cprojects_fpm/?sap-client=300&sap-client=300&STARTVIEW=Tasks&OBJ_EVENT=TTOC81F66B8A8F51ED3BEDB4083DBDBCE57C81F66B8A8F51ED3BEDB4083DBCD6E57DPO&sap-sessioncmd=open&sap-wd-configid=CPROJECTS_FPM&sap-language=ZH</a>
</body> </html>
So the result is, if I directly click the htm file it leads to the error page, but if I click the preview text it goes propertyly.
Regards
