A device may receive, from a user device, a request for a code assessment of a proposed change to an enterprise resource planning (ERP) system of an organization to identify an impact of implementing the proposed change on custom code associated with the ERP system. The device may obtain data identifying custom items associated with the custom code from a data structure associated with the ERP system. The device may generate custom code metadata for the custom items by performing error checks to determine whether the custom items will cause errors after the proposed change is implemented. The device may generate an assessment report for the code assessment by processing the custom code metadata. The device may provide the assessment report for display on an interface of the user device, and may perform actions to permit the proposed change to be implemented without the errors occurring.
