SAP Error Message - Details

• Message type: E = Error

• Message class: ARC_DAS_CON - XML DAS Connector: Messages

• Message number: 127

• Message text: No migration possible from &1 to &1 for BOR type &3 and doc. type &4

What causes this issue?

An existing resource on a WebDAV archive store is to be assigned to
another WebDAV archive store. Presumably you have changed an existing
rule, so that the WebDAV archive store is now changed. A migration of
existing references is not possible.

System Response

The WebDAV archive store was not changed on the existing resource of the
processing BOR type and the document type. Thus the original storage
location is kept.

How to fix this error?

Check the storage rule for the BOR type and the document type.
If you want to store new resources not yet stored which belong to the
BOR type and the document type on another WebDAV archive store, you
should use a suitable selection to ensure that resources already entered
are not selected again. Otherwise, this will only have a negative effect
on the running times.
