Unable to delete records from some tablesIssue Unable to delete records from some tablesReleaseLondon Patch 4 HF 2CauseWhen some records get deleted, these records get stored in a "shadow table" (in the case that a Rollback is needed). Since this table did not have a limit as to when to stop creating and storing "back-up" records, the table was too big in size and the alter took so long that the transaction timed out. This prevented the deletion of the records. ResolutionAdding the "glide.rollback.expiration_days" system property (of String Type) with a value of 7, limited the days which the backup ("in case of rollback") records will be stored and allowed the deletion of the records from the UI (user interface).
