Diagnosis
The name of source system &V1& lies in the namespace for deliveryversions of objects SAPxxxxxx or R/3xxx that are sourcesystem-dependent.

System Response
The source system can be defined. Note, however, that transformationscannot be copied from the BI Content if these transformations areassigned to delivery version &V1& (this also applies for all futurecontent).

Procedure
Delivery versions are normally named thus: R/3 andSAP with numbers in the formats [1, 2, 3, ...]and [000001, 000002, 000003, ....]. SAP andthe component names are also used sometimes. None of these conventionsare mandatory though.
Provided that &V1& does not clash with the naming conventions specifiedabove, you can create the source system with this name. Otherwise, youshould consider renaming it using transaction BDLS inorder to prevent clashes with BI Content. Note the limitations oftransaction BDLS for productive systems though. Contact SAP Support ifnecessary.
