Taken from other thread:
If you need to delete instances of a particular business object you can either use a query in your application with the delete operation enabled for multiple instances, or configure a process with two rules like these:
FIND ALL MyObject
DELETE MyObject
a)I have created a query with Delete operation enabled for multiple instances. This displays all queried values with a chcek box beside them and the delete operation at the bottom. Is there no way of 'Selecting All'
b) I then tried the process as above. It displays the query result with all values and radio buttons. If you select one and contine it takes a long time but does nothing.
I've checked the user manual, is there a step I am missing or can the select all be available.
