The yab.log file contains the output from rebuilding the indexes in the QAD Enterprise Edition database during the conversion execution stage.

The new unique index oid_<table name> can cause these errors. OID fields were available in some pre-QAD Enterprise Edition versions, but uniqueness was not enforced. This new index is used to enforce the uniqueness of OID fields.

Analyze and correct these errors before proceeding with the conversion. For OID fields, you can reset them to zero and the conversion regenerates them. Some OID fields are used as foreign fields and require manual correction.
