Hi There,

We got a requirement to add a DFF for the receipt lines under the transaction tab the advance collection module.

For transaction lines we have unpaid reason standard field to add some extra information. But for the receipts the unpaid reason is getting greyed out and we expect to create a DFF for the receipts to add some additional details.

Kindly let me know if there is any way to achieve this.
