System Response

Program RPRFIN00_40 for creation of posting runs requests a new posting
run number for each run. The number range object for the posting run
number is, however, locked until creation of the posting run has been
completed. During this time, the system prevents other users from
starting the program.

How to fix this error?

Wait until user &v1& has stopped using the program. If the program is
still locked after user &v1& is finished, please contact your system
administrator.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
