SBL-DAT-00500 error is displayed when Quote Item List View is opened.
View has Quote Header Form Applet and Quote Line Item List Applet. Usually this will work most of the times, however when number of records is more than 10K 'Hirarchy Parent Field' property causes this error.
Solution 1: Clong Quote Item List Applet and disable hierarchy functionality by adding a user property :
Name: Disable Buscomp Hierarchy
Value : TRUE
Solution 2: Disable hierarchy functionality on quote item business component, by disabling
User property : 'Hierarchy Parent Field' from Business Component.This would remove hierarchy from entire application.
This error is duly recorded in case of execution thread is a business service or workflow. However it confuses a bit when it happen just after view is accessed.
