Summary :
This SAP Note identifies issues in ALV Grid where special characters like Umlaut get distorted during duplicate row operations, and users encounter "invalid XMLBLOB data error" post data entry or save actions. The problems, introduced from SAP GUI 720 patch level 10, stem from the ALV Grid's GetCellText() method, which improperly converts data pre-transfer. Resolutions involve applying a forthcoming patch for SAP GUI for Windows, detailed in the "SP Patch Level" section or external references like Note 1053737. Users should install this or subsequent patches since SAP GUI updates are cumulative, addressing issues comprehensively.
