Hello,
I am using ' CRM_ORDER_MAINTAIN ' for change my opportunity STATUS and Reason For Rejection. When I change opportunity status from OPEN to LOST , also pass Reason For Rejection and press save button then opportunity save successfully done. But when i again click on save button more then one time for this same opportunity with same screen and same status then it is giving below Express Information and below DUMP is coming in ST22. Please help me what can i do for remove this error.
