Hello,
 
We changed the values of divisions for several eprintids in the eprint_divisions table in mysql to move them in bulk to another division, then did generate_abstracts which gave the correct results but with the bellow error , then did generate views which also gave correct results and actually moved them to the new divisions, one thing we noticed is the divisions value in the eprint__ordervalue_en table did not change to the new value , will this have any effect anywhere? 
this is the generate_abstracts error we received:
