Update of the column 'Reference' in the More tab of the Lines window

Dear Sir,

Our customer has a business requirement to update the column 'Reference' in the More tab of the Lines window.

Please let me know the answers to the following questions in this regard:

2. In which column and table the value of the column 'Reference' in the More tab of the Lines window in Receivables is stored?

3. Is the value in the column 'Reference' in the More tab of the Lines window updated based on the setup of the field 'Reference Field Default Value' of the Transaction Source?
