Initial Load error "valid to date is in the past"

Hi,

During the Initial Load from SAP i get the following error:

The specified "Valid to" date is in the past:Attribute: MXREF_MX_PRIVILEGE

Is it possible anyway to assign the invalid role to an user? Or is it a must to clean the SAP data with program PRGN_COMPRESS_TIMES?

Thanks and regards

Florian
