Accessing values during runtime in value mapping

Question

Hi all,
We have a specific requirement , where in we have a set of fields coming from the source system. All the fields have values expect few. The few which don't have values are reserved for future use, and for each source field there is a corresponding target value and we need map them.
We have used value mapping here, but it doesn't work for fields which don't have values.
We have thought of  accessing the fields which do not have values, dynamically or at runtime by connecting the database of the source system.
Is it possible to do this, if yes, please provide with your inputs and alternatives.
thanks,
younus

<b>To implement Value Mapping, following activities have to be performed:</b>
<b>1.</b> Register Java Proxies. This is one time activity for each installation. Following URL has to be called for registering asynchronous replication scenario:
http://<Server>:<Port>/ProxyServer/register?ns=http://sap.com/xi/XI/System&interface=ValueMappingReplication&bean=localejbs/sap.com/com.sap.xi.services/ValueMappingApplication&method=valueMappingReplication
<b>2.</b> Application Programming: ABAP program has to be written to perform following tasks:
<b>a.</b> Read Value Mapping data from table.
<b>b.</b> Call Outbound Proxy to push the data into a message to Integration Server.
<b>3.</b> Configuration of Replication scenario in Integration Directory.
