Error 4530: Base pay is in an invalid format. Format must be 999999.99 04 August 2022 13:33 This error means the base pay is entered in a format not expected by the DfE. To check this: go to Admin > Personnel > Staff find the member of staff click onto the black cog next to contract amend the base pay and update. A contract with 0.00 as Base Pay will also generate this error, as a positive value needs to be entered (e.g. 11868.72) Ensure you check all contracts in scope for the Workforce Census, as there may be a missing base pay figure on an expired contact.
