Answer 1

Create a multi-value parameter ({?Customer Name}) with these properties:

• Default Value: ALL
• All multiple values: TRUE

Add a row to the parameter's pick-list grid; supply 'ALL' and 'ALL' (without single quotes)

Create a Custom Function (named 'Delimit') with this text:

// Delimit()
// enclose each value in array in **, returning an array
Function (Stringvar Array params)

  Split("*" + Join(params, "*,*") + "*", ",")

Modify the report's record-selection formula:

If {?Customer Name}<>"ALL" Then
    {TABLE.CUSTOMER_NAME} LIKE Delimit({?Customer Name})
Else
    True

Optionally, create a formula to display the parameter's values with this text:

//{@Customer Name}
Join( Delimit({?Customer Name}), ";")
