Hi Mieke,

If you want the exact function resource (pseudo code):

var functionID = Guid.NewGuid();
var dveElement = new LiteElementInfoEvent();

//server filter
FilterElement<Resource> dveFunctionFilter =
    FunctionResourceExposers.FunctionGUID.Equal(functionID).AND(
    FunctionResourceExposers.MainDVEDmaID.Equal(dveElement.DveParentDmaId).AND(
    FunctionResourceExposers.MainDVEElementID.Equal(dveElement.DveParentElementId).AND(
    ResourceExposers.DmaID.Equal(dveElement.DataMinerID).AND(
    ResourceExposers.ElementID.Equal(dveElement.ElementID)))));
//client filter
Predicate<Resource> dveFunctionPredicate = r =>
{
    return r is FunctionResource fr && fr.FunctionGUID == functionID &&
           fr.MainDVEElementID == dveElement.DveParentDmaId && fr.MainDVEElementID == dveElement.DveParentElementId &&
           fr.DmaID == dveElement.DataMinerID && fr.ElementID == dveElement.ElementID;
};

If you want the entry point (pseudo code):

var count = 0;
_config = new FunctionResource();
FunctionEntryPoint[] entryPoints = new Skyline.DataMiner.Net.Messages.ProtocolFunctionHelper().GetFunctionEntryPoints(_config.FunctionGUID, _config.MainDVEDmaID, _config.MainDVEElementID).ToArray();
bool IsSameEntryPoint(EntryPointData entry)
{
    return entry?.Element != null && entry.Element.DataMinerID == _config.DmaID && entry.Element.EID == _config.ElementID;
}
while (count < entryPoints.Length && wrapper == null)
{
    if (entryPoints[count] is FunctionEntryPoint data && data.Data is EntryPointData[] arrayData)
    {
        var dataCount = 0;
        while (dataCount < arrayData.Length && wrapper == null)
        {
            if (arrayData[dataCount] is EntryPointData entry && IsSameEntryPoint(entry))
            {
                wrapper = new EntryPointWrapper(entry, data.ParameterID);
            }
            dataCount++;
        }
    }
    count++;
}
