Project Create Accounting based Expenditure Batch -Transaction Source

Hi All,

We are using 4 user defined Transaction Source in PA mapped to Expenditure Type Class as 'Miscellaneous Transactions'.  Upon cost distribution and generate accounting events, client want to transfer expenditures to GL based on PA Transaction Source. PRC: Create Accounting shows process category as 'Miscellaneous Cost' however within this category we don't have an option to select Transaction Source.

How to address this business requirement ? Is there anyway to add new Expenditure Type Class  at Pre-Approved expenditure batch level ?

Regards,

AJ
