Writeback Text Accounts with Integration Agent

Summary:

Hi,

I have created a writeback outbound integration to write data from the OEP_CPX cube to a table in the On premise database with the help of EPM Integration Agent. However, in the writeback, I see that the text value accounts are missing and only the numeric data is present.
Specifically I am looking for OCX_Asset Decription which is an Account that I am populating with data.
I want to take the value of this account in the writeback as well.
A mapping is out of the question as there will be data added to EPM which will not be maintained anywhere else and hence the data has to come out of EPM and ideally without any manual steps.
