Can Receipt Method be Updated using the FBDI CustomerImportTemplate?

Summary

Need to change the Receipt Method on Customer Accounts.

Content

ADFDI customer spreadsheet works only for Organization Customers so will not work for us.

We are using the RA_CUST_PAY_METHOD_INT_ALL tab on FBDI CustomerImportTemplate.xls  There is no update indicator field on the tab.

Have made numerous different attempts.  Tried changing the existing Primary Indicator to N first, tried end dating the existing RM, tried adding a new receipt method, etc., no success.  Error message received is – “The specified date range for the receipt method overlaps with an existing date range”
