In AX 2012 R3, i have run foreign currency revaluation. Transactions/vouchers have got generated - both AP revaluation as well as AR revaluation.
But in AX, is there any easy way to find, the source invoice for which the foreign currency revaluation has been created?

(Above screen shot) --> Foreign currency revaluation voucher - IN2EXAJ000139201 has been created by AX as a result of revaluation run. The currency is EUR (that is shown by AX).
What is the invoice for which this transaction has been created?
What is the source transaction in AX with reference to which this foreign currency revaluation is created?
For some rows, the invoice lines have the invoice reference, but for other lines the invoice field is blank (as in the screen shot).
In such cases, where the invoice field is blank, how to identify the source invoice or any other such source transaction for which the foreign currency revaluation has been created?
Especially when there are thousands of such lines (with no invoice reference) is created by AX.
Many thanks for your advice and guidance in advance.
