Hi Experts,

I used this discussion to re-write the script in different way:

Return List of Rows by Groovy — Cloud Customer Connect (oracle.com)

This is my script:

def vo = newView('MY_BO')

def myRequest = MY_INPUT

addBindVariable(vo,'requestNumber','Text')

setBindVariable(vo,'requestNumber',myRequest)

vo.appendViewCriteria("requestNumber = ${myRequest}");

vo.executeQuery();

def map = [:];

while(vo.hasNext()) {

 def row = vo.next()   

 map.put(row.requestNumber,[row.id,row.Number,row.status])

}

return map;

myRequest has two rows but when I test it, returns only the last row.

when I run it without filtering it returns all the rows in my BO.
