My application insert one record that have type and value
When I insert this record a report to the other application that I make it.
Then, acording the type and value, the other application have to determine the destination of this data. Can send to the company A, B or C.
The company A, B or C have to stay with equivalent type and value.

If my application have:
- 3 records of type "1" and value R$ 100,00 then
- the company A have 1 record of type "1" and value R$ 100,00
- the company B have 1 record of type "1" and value R$ 100,00
- the company C have 1 record of type "1" and value R$ 100,00
the tree company have equivalent type and value

To determine what company have to receive the data, the other application execute many instructions to consult the last situation and save the new situation - this instructions my application don't know, than I do not can use a batch command.

I just say to the other application: "I inserted one record of the type '1' and value R$ 100,00"

something like
objDefiner.define("1", 100.00)

Then I need

myApplication.beginTransaction()
otherApplication.beginTransaction()
insert into my table...
objDefiner.define("1", 100.00) && of other application
if error
  myApplication.rollbackTransaction()
  otherApplication.rollbackTransaction()
else
  myApplication.commitTransaction()
  otherApplication.commitTransaction()
endif
