1737650 - EHP7 for SAP ERP 6.0 SP Stacks - Release & Information Note
Activation of DDL sources fails during EHP update due to missing namespace not yet in the system . To work around this issue , ignore the error in SUM ( "Accept non severe errors " ) and proceed with the update . Post update , please implement the note 2016248 which activates the DDL sources.
note 2016248
A missing namespace now results in a warning rather than an error message. The DDL source is activated if there are no further errors.
If the error occurs during an upgrade or import and you cannot implement this SAP Note, then ignore the error. You must then also reactivate the DDL source after the upgrade or import. You can use the program RUTDDLSACT in transaction SE38 to do this. You must specify only the name of the DDL source. If the program is not already in your system, you can use SAP Note 2023690 to implement it.
