• Message number: 104

What causes this issue?

Pooled and cluster tables must be assigned to a physical table pool or
table cluster. The physical pool or cluster for the pooled or cluster
table which you are processing is not active. The table therefore
cannot activated.

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?

Check whether a physical pool or cluster has already been assigned to
the table. If this is the case, you need only activate it. You obtain
the maintenance screen of a pool or cluster by selecting <LS>Utilities
-> Pool/Cluster -> Change pool/cluster</> in the initial screen of the
ABAP Dictionary.
Otherwise you must assign a valid pool or cluster to the table. The
existing physical pool or cluster can be selected with the R/3
Repository Information System. If necessary, create a new pool or
cluster with <LS>Utilities -> Pool/Cluster -> Create pool/cluster</> in
the initial screen of the ABAP Dictionary.
