Summary :
After an update termination in SAP, ABAP runtime error "IMPORT_UNEXPECTED_END_OF_DATA" occurs specifically in module ARFC_DEL_LUW_WITH_VB_REQUESTS within SAPLARFC or LARFCU44, accompanied by hanging queues in t/qRFC monitor. This arises due to incorrect status handling in asynchronous RFC with function ARFC_END_VB where zero value error occurs in new update requests, exacerbated by outdated kernel patch levels. Solution mandates importing a kernel with the specified or higher patch level, with no available workaround.
Key words :
/qrfc monitor displays hanging queues, 'sp patch level' tab page, v1 function modules call, abap runtime error occurs, abap runtime error, function module arfc_end_vb, function module arfc_del_luw_with_vb_requests, patch level, error occurs, function arfc_del_luw_with_vb_requests
