Object & in table TRDIR is locked; see the long text for this message

What causes this issue?

The system tried to access a generated program for the analysis
structure. However, it was unable to do so because table TRDIR is locked
for this program prefix.

System Response

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

How to fix this error?

Table TRDIR for the generated reports of the analysis structure is
normally locked for a short time only. The fact that the table has been
locked for a long time means that an error occurred during the regene
ration of the program environment for the analysis structure. Use
transaction JBRGE to regenerate the program environment again. If errors
occur again, delete the lock manually in transaction SM12. Then restart
transaction JBRGE.
