How to default Charge Account Segments based on Employee Expense Account in Requisition

Hello All

We have a requirement to default Charge Account Segments based on Employee Expense Account in Requisition.

Business Case - We have multiple common expense items which are procured across multiple departments in our organization. Users creates requisition for each of these items but they have to change the department every time after the default account has generated. The requirement is to generate the charge account by picking 1 segment from Employee Expense Account and rest AS-IS.

As, this specific segment will have the department code of the requestor.

Please suggest, how to configure these rules to default the charge account for the expense item in Purchase Requisitions Distributions
