Upgrade to Netweaver 7.4 SR1

Hello,

I'm doing a upgrade from Netweaver 7.3 to 7.4 SR1.

The phase ACT_UPG stop because the job RDDMASGL fails with the short dump: CREATE_DATA_UKNOWN_TYPE.

The short text of the dump is:

CREATE DATA: The specified type ("\CLASS=CL_QLAST_ASSOCIATIONS") is not a valid data type.

Could any expert help me?

Best regards,

Xavier Garcia
