Personalize APXINWKB to exclude a Transaction Type

Good morning gurus,

We have a read only AP responsibility that is used more or less all throughout our organization

We have just started to pay Expenses through AP

We would like to exclude (Responsibility specific) any queries executed so they do not retrieve transactions where the Type is "Expense Report"

I know I will need a form personalization to do this

Can anyone help me on how to do this or point me toward a useful MOS document

I have put an example in the attached

Many thanks, David
