If the medTester uploaded files include errors, Invalid Control ID is one of the possible errors.
This error occurs when the biomed equipment item does not have a record in WebTMA. To fix the error, click the Control ID field label hyperlink to open the Biomed Equipment window in a new window and create a new record for the item. Once the new record is saved, look to the medTester Exception window. Click the Create WO link on the Action Menu to create a new work order.
