hi ,
i want to set the value …with out hard coding … i mean with out set value option . set the value for a perticular variable globally

In this case you better load default properties using propertyfile(key/value pair) method and retrieve/access the values globally based on the key.Also you can use specifications signature for accessing global based values in the flowservices.

Search this forum on how to create/develop propertiesfile accessing sevices etc…there are many threads discussed on this topic.

HTH,
