Don is right on the use of qualifiers, but I'm not seeing them here.
I'm including a screenshot of the 'shell game' for managing / controlling system naming with 'long names'.
I think something like this should work for your example:
CREATE VIEW VWACTDTL (
ENTITY_TRUST FOR COLUMN CUSACC);
rename view VWACTDTL to Account_Detail_View
for system name VWACTDTL;
