You may end up with the below error message when you are performing an import/export of an SAP systems, in such cases, execute "R3load -merge_bck -e|i

file C:\Program Files\sapinst_instdir\ERP\LM\COPY\MSS\SYSTEM\CENTRAL\AS-ABAP\SAPAPPL1.TSK possibly corrupted             a previous run may not have been finished cleanly(TSK) ERROR: file C:\Program Files\sapinst_instdir\ERP\LM\COPY\MSS\SYSTEM\CENTRAL\AS-ABAP\SAPAPPL1.TSK.bck already seems to exist

Example : R3load -merge_bck -i SAPAPPL1.CMD


Before Merge




Quick Tip : If you are running an import manually using R3load command, then you can use -merge_bck parameter in the command line itself (i.e.  R3load.exe -i SAPAPPL1.cmd -dbcodepage 4103 -l SAPAPPL1.log -merge_bck -loadprocedure fast)

Please note that .bck file is a key for the successful restart of an export/import, so make sure to handle it with care.
