When we try to deploy our bar file to our execution group we get this

BIP1549E: Unable to find required execution group document in the
configuration repository.

When deploying configuration data, the document for execution group
'3d9678a5-0201-0000-0080-a147763debdb' could not be found in the
configuration repository. Another document has referenced this
document, and it is required for the successful completion of the
deploy operation. The referencing broker document is of type 'null'.

The execution group document '3d9678a5-0201-0000-0080-a147763debdb' is
not available. This is an internal error. Contact your IBM support

Does anybody know what this means ???
