that ended unexpectedly. Only the first WBS element is listed.
The error could be related to this WBS element.

How to fix this error?

Activate the checkpoint group <AB>PMMO_DISTRIBUTION </>using the
transaction
<DS:TRAN.SAAB> SAAB
.</>
Set the radiobutton <ZK>Break</> in the section <ZK>Breakpoints</>. Run
distribution again online until the system stops at the breakpoint for
failed RFC sessions.
Check the field content of the internal table
<AB>IS_RFC_PARAMS-IMP-T_GROUP_WBS</>. Use the entries in this table to
run distribution just for those WBS elements. If possible, run
distribution with the parallel processing option deactivated. This will
make it easier to debug the error.
