Currently the DonorCentral Site does not accept Organization IDs which contain alpha characters. Currently Organizations with IDs that include alpha characters are not able to be uploaded to DonorCentral, thus preventing the display of gifts and grants relating to those Organizations.
These profile IDs cannot simply be changed in FIMS as 1. this is not allowed in FIMS, and 2. there is already grant data for these orgs.
This is on our roadmap for the new DonorCentral.
