I have recently encountered below error when working with Hyperion planning.

Communication error with server. Callback failed for data entry page. 

There was a problem in the software code in the jsp file: EnterData_Inner.jsp which is executed when opening a Planning web form.

Steps to reproduce the error
The issue can be reproduced at will with the following steps:
1. Log into Workspace and open a Planning application.
2. Open a form.
3. Get error above.
2. <Add step details>

Proposed Solution or workaround.
During the troubleshooting found that this was a Bug and it is fixed in “Patch Set Update: Oracle Hyperion Planning, Fusion Edition” or “patch 14126387”.

Also issue this is fixed in PSU .600 patch, but you will have to apply patches other products as per-requisites.
