This are the suggested steps:
1. From ALM, go to the following path:
Tools -> Clear History (in the linked project)
With this, we can reduce the size of the table AUDIT_LOG and AUDIT_PROPERTIES.
2. Manually from the Site Administrator run this query:
Delete FROM AUDIT_LOG WHERE (((AU_ENTITY_TYPE = /*P*/'RUN')) AND LOWER(AU_ACTION) NOT LIKE 'ca\_%' ESCAPE '\') AND AU_ACTION_ID NOT IN (SELECT DISTINCT AP_ACTION_ID FROM AUDIT_PROPERTIES)
3. Try the Cross Prject Customization again.
