API to update Other Internal Funding Source Name

Summary:

The Import Funding Sources FBDI allows to create Internal Funding Sources. But once the Funding Source is created, same FBDI does not allow to update the Name and throws error : FND_CMN_RCRD_VAL A record with the value 999999 already exists. Enter a unique value.
Is there any SOAP or REST API that allows to update the Name?
