Storing Item Receipt number in Bill and Bill number in Item Receipt

Requirement

There is a bill button on the IR record and if the user clicks the bill button from the IR record, the IR number should populate to the custom field in the bill record. And once the user saves the bill, the corresponding bill number need to be stored in a custom field in the IR record.

Solution

Create two custom fields to store the Item Receipt Number in Bill and the Bill Number in Item Receipt.
