EP_00020 Error in retrieving bank details following entities 361. I got this error, what does entities mean? im lost on this one.

Might mean vendor or employee depending on whether you are trying to pay a vendor bill or employee expense. 361 is the internal ID of the vendor/employee for whom either bank details do not exist or the bank details are inactive (typically the case when you have approval in place). Also make sure the vendor/employee has the EFT Bill Payment checkbox checked on the EFT subtab.
