Hi Miaio,

The protocol Action should be able to do what you want. Inside the action, you need to use the Protocol.Actions.Action.Type set to clear and Protocol.Actions.Action.On set to parameter.

An important note in the DataMiner Development Libary is:

If you perform a “clear” action on a parameter, you must also perform a “clear” action on the response in which that parameter is used. In case of a table parameter, the memory is also cleared client-side. There is no need to add a “clear on display” to see the result. If the parameter is not a table parameter, the memory is not cleared client-side. In that case, the extra action will be needed.

Example

<Action id="899">
<Name>ClearParameter</Name>
<On id="800">parameter</On>
<Type>clear</Type>
</Action>
