In SAP BPC 10.0 how can i send data between models, using text data in the source as link?

I have  a source model where the user needs to register a text like 2013.03 (which indicates the start date of a cash flow) and a cash amount to be sent to a second model. In the other side, i have a second model where i need to move  the mentioned amount divided by a number of duration periods, starting just in the correct date that was registered in the source model.

How can i do this?

Note: Please check the attached images

First one: Source Model

Second one : Target model, expected result
