for the epa, make sure they are exported from nw7.3 system.
fill the name for the project.
Thank you very much for the great reply!
But I have one more problem: Now I can include only the PCD content in the SCA file, meaning that there is no EAR/PAR files in the package. How can I include them in my package?
An explanatory answer like above would be highly appreciated 
I created the EAR from the PAR migration tool on the portal.
And I have already done what's said in the link in your first reply. But when I export, it is not visible in "the local contained development components to build". Only the DC which wraps the EPA file is visible. So when I deploy it and try to preview it, it gives an exception.
The application project looks separate from the DC including the EPA. How can I include them in the same package or how can I relate the EAR project to the DC including the EPA?
