Thanks for the reply. I should describe the questions more clear.
There is a parent-child relation between two BOs. In parent BO's edit/create form, the child BO is displayed in "Table of items" with the default presentation of the child OB's table.
My questions are:
whether can specify a self-defined presentation for the child BO table displaying in parent BO's edit/create form? and can specify such self-defined presentation for the child BO through 'Reference element' dialog box?
Understand can define an operation in the presentation of the parent attribute and the operation will be displayed next to the referred instance. However, since the operation is not for each instance of child BO, but for all instances in table of child BO, I'd not like to add icon for the operation next to the each child BO's instance. I'd like to add a icon at the bottom/top of the table of child OB, just like at the position of "Add", "Add New", "Delete All" icons.
Thanks,
Mojun
