| Context: | Message |
| OCL: | self.Transaction->asSequence().Amount->at(0).max(self.Transaction->asSequence().Amount->at(1)) = 100 |
| Description: | The example rule compares the larger amount from the first and second transaction amounts to the right side operand. It's assumed that there is at least two transactions. The 'at' method doesn't work with the Bag type so it has to be changed to Sequence. |
