Customization of Create Accounting related program

Dear All,

We have requirement to dynamically default the GL batch name parameter based on system date in the format of DD_MM_YY whenever we run or schedule the Create accounting or Transfer to journal entries to GL, so that all the journal batch name will have sysdate as prefix.

Example: DD_MM_YY <application default contents>

We are using more than 20 primary ledgers and hence we want to follow the discipline GL batch name, any suggestion how to achieve the same?

Fyi..we were trying to create new custom request set and do the changes to the standard create accounting program only for GL batch name parameter and we had challenge for schedule request which were not taking the current sysdate instead considering the date on when the schedule was done.
