· Upgrade to at least IBM 5.3.2 as required by iFix and then apply iFix that includes APAR PJ45804
--OR--
· Upgrade to Business Automation Workflow V19.0.0.3

IBM Case Manager V5.1.1, V5.2.0, and V5.2.1 are no longer in full support; IBM recommends upgrading to a fixed, supported version/release/platform of the product.
