+# NotReplicated
+
+- **引擎模块：** Blueprint, Network, Parameter
+- **作用机制：** 在PropertyFlags中加入[CPF_RepSkip](../../../Flags/EPropertyFlags/CPF_RepSkip.md)
+
+参照UFUNCTION的ServiceRequest，该标识符弃用。
+
+“Only parameters in service request functions can be marked NotReplicated”
+
+```cpp
+if (context.PropertySettings.PropertyCategory == UhtPropertyCategory.ReplicatedParameter)
+			{
+				context.PropertySettings.PropertyCategory = UhtPropertyCategory.RegularParameter;
+				context.PropertySettings.PropertyFlags |= EPropertyFlags.RepSkip;
+			}
+			else
+			{
+				context.MessageSite.LogError("Only parameters in service request functions can be marked NotReplicated");
+			}
+```
+
+源码里只知道
+
+```cpp
+// Currently some features such as not replicating all parameters isn't allowed on regular RPCs
+UFUNCTION(ServiceRequest(Iris))
+void FunctionWithNotReplicatedNonPODParameters(int Param0, bool Param1, int Param2, UPARAM(NotReplicated) const TArray<FTestReplicationStateDescriptor_TestStructWithRefCArray>& NotReplicatedParam3);
+void FunctionWithNotReplicatedNonPODParameters_Implementation(int Param0, bool Param1, int Param2, UPARAM(NotReplicated) const TArray<FTestReplicationStateDescriptor_TestStructWithRefCArray>& NotReplicatedParam3);
