I found one instance of this error and the stated solution was to regenerate the OBIEE extract files which we did.  We ran the Data Lineage load plan early this morning and it ran the SQL Parser step (6) correctly, but failed on the Dashboard source (step 8) - which at the time we had the dashboard extract from an incorrect version (11.1.1.7.1).  I attempted a reload skipping the dashboard steps (to see if the other steps would complete), but it failed on the parser on run #2.  We were then able to get the catalog installed at 11.1.1.7.0 and redo all the extracts, but it keeps failing on the SQL Parser with the following error:

ODI-1519: Serial step "DATA_LINEAGE (InternalID:4220174002)" failed because child step "Dimension_ETL (InternalID:4254366002)" is in error.

I am stumped as to how it could have run once this morning, but since then keeps failing.  We also cleared the directory and put re-regenerated extract files out on the server to ensure something wasn't stuck from an existing file.
