I want to delete outbound IDocs from my system.

I am using below method to delete outbound IDoCs:

1. Archive RSEXARCA and RSEXARCB (SE38)

2. Delete RSEXARCD through T code SE38.

When I am trying to archive the IDoC, I am getting below error message :

archive file /oracle/temp/SARA/BC_IDOC_2019062018_144849_0.ARCHIV cannot be opened for write program
