SAP Error Message - Details

• Message type: E = Error

• Message class: UCM0 - Messages for Data Basis, Cons Area, ...

• Message number: 154

• Message text: Data basis &1 needs to be generated (after upgrade)

What causes this issue?

After the upgrade to the current SEM release, the
<DS:GLOS.3C14A7065A82D511B1250008C784EFB1>data basis</> must be
regenerated. Normally, the system automatically regenerates the data
basis the first time the Workbench is called after the upgrade. However,
the internal representation of the data model of the data basis &V1&
suggests that no such regeneration occurred.

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?

Call the maintenance function for data basis &V1& in display mode. Go to
the <LS>Data Streams</> tab page and choose <LS>Generate</>.
If changes to Customizing settings are permitted in the current system o
r client, you can alternatively call the data basis in the change mode
and save. In the case of systems supplied with Customizing transports,
you can alternatively generate the data basis in the source system and
then transport it again.
