SUBJECT column of WF_NOTIFICATIONS table being limited to 240 characters for Workflow Message

Hi All,

I'm facing an issue with Workflow notifications which I would like assistance with:

I have modified the subject of a Workflow message such that it is within the 240 character limit of SUBJECT column of WF_MESSAGES_TL where the definitions of Workflow messages are stored.

The Subject is as follows :

Approval for Invoice &#HDR_INVOICE_NUMBER has been escalated to you as the manager of &DOCUMENT_APPROVER since he/she has not responded. If in any doubt as to whether you should approve this invoice, please check with the original approver -- (which is 239 characters).

As I understand, the message attributes &#HDR_INVOICE_NUMBER and &DOCUMENT_APPROVER will take values dynamically during the cycle of the workflow and will definitely vary in size.
