Attribute check table error

Hi,

We have added a few attributes to a custom data model and some of them contain data elements which have check tables with more than one key field.

This is resulting in an error during data model save. As a workaround, we tried to create this attribute as an SU type 3 but due to this our BRF+ validations stopped working for some reason and we have to revert back to using an attribute.

Can someone please help us figure out how we can handle these attributes in the data model?

Thanks,
