There is currently no checking of open payables (A/P, grants, etc) when a fiscal sponsor is added to the supported org's profile record. This is means anyone adding a fiscal sponsor would be required to manually update grant records (for example) with the correct payee information. This is in stark contract to the address maintenance tool that prompts you when a record's contact information is updated AND they have an open payable. The current structure requires that the user both knows this behavior of FIMS AND knows that there is an open payable *somewhere* in the database AND has the permissions to edit it.
Not having this check results in payments being made to the wrong organization, adds time to funding cycles, and makes funders look bad. It also goes against good funding practices and could easily happen if more than one person update records in FIMS.
