in

OBIEE version : 12.2.1.0.160719
OBIEE Client tool : 12.2.1.1.0

Cause: Not included some class files.

Solution:

To work around this issue, you can replace the binaries in the 12.2.1.1.0 client from the 12.2.1.0.0 client to make it work successfully.

Steps:

Take a backup of the below files

1) Navigate to the location

 C:\Oracle\Middleware\Oracle_Home\bi\modules\oracle.bi.commandline.tools\scripts

Rename datamodel to datamodel_12.2.1.1.0

2) Navigate to the location

 C:\Oracle\Middleware\Oracle_Home\bi\common\templates\wls

Rename: oracle.bi-commandline-tools-template to oracle.bi-commandline-tools-template_12.2.1.1.0

3) Navigate to the location

C:\Oracle\Middleware\Oracle_Home\bi\lib

Rename: bi-commandline-tools to bi-commandline-tools_12.2.1.1.0

Then copy the files  from the 12.2.1.0.0 client. To the above location

4) Navigate to the location

C:\Oracle\Middleware\Oracle_Home\user_projects\domains\bi1\bitools\bin

Take a backup of the file datamodel.cmd then edit datamodel.cmd file

Change the call statement as shown below

call "C:\Oracle\Middleware\Oracle_Home\bi\modules\oracle.bi.commandline.tools\scripts\data-model-cmd.cmd" %*

After this try to upload the RPD again 

After this step upload rpd successfully worked for me.
