PO Charge Account Generation

Hi,

For an employee creating purchase requisition for expense POs(without any item code), the default expense account is set in Employee assignments screen with Ledger say Ledger1.

While creating Requisitions, charge account is generated correctly.

But if the same person need to create Purchase Requisition for Ledger2, charge account is not generated.

Please advise what are the setups to be done to enable an employee create Purchase Requisition under multiple ledger and charge account to be generated .

Thanks,
