Hello Harm,

I have solved the bug, the cause of the error is , in the DDO structure
a DDO is added manually which is constrained to the parent DDO(i.e
stock). So while initializing the grid it is not getting the
vdfMainTable="Stock". I have removed the "Set Constrain_file to
Stock.File_number" from the added DDO and the error is gone.

Thank you for reply.

Warm Regards,
