SAP Error Message - Details

• Message type: E = Error

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

• Message number: 057

• Message text: Data stream &3 already being used in data basis &4

What causes this issue?

Data stream &V3& is assigned to
<DS:GLOS.3C14A7065A82D511B1250008C784EFB1>data basis</> &V1& for data
stream type &V2&. However, this data stream is already being used in
data basis &V4&. Thus, the assignment of the combination of RFC
destination and InfoCube to the data basis is no longer unique.

System Response

The definition of data basis &V1& cannot be saved with an error.

How to fix this error?

Compare the definition of data basis &V1& with the existing data basis
&V4&. Check if you can do without data basis &V1& altogether to allow
for a new <DS:GLOS.D5692F24DA2CD511BCBF0800060D9C68>consolidation area
</> under data basis &V4&.
If you require both data bases, choose a different data stream for type
&V2& by changing either the RFC destination or the InfoCube.

Procedure for System Administrators

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