transaction matching writeback to EBS

Summary:

Writing back to EBS from transaction matching with "Data export to On Premise Database"

Content (please ensure you mask any confidential information):

I'm trying to export a journal (created from transaction matching) to EBS within a Data Integration.
I have created a source application "Account Reconciliation Journal Adjustment", and a target application "Data export to On Premise Database",
where I do an insert into the GL_INTERFACE table.
But I'm not able to manage the amount as it's not a dimension and there is no mapping for it (I need to insert into entered_cr or entered_dr depending on the sign of the amount).
