**SetMRPSize( **//MRPSizeFlag//**// //****),VIRTUAL**

{{blk2blue.jpg|blk2blue.jpg}}

| **SetMRPSize** | Sets the value of the **UseMRP** property. |
| //MRPSizeFlag// | A BYTE value that sets the MRPSize property value. |

The **Set****MRPSize**** **VIRTUAL** **method is used to set the value of the **MRPSize** property. This property is used in conjunction with the IP Driver processing of Multiple Request Packets.

**Implementation:**

**S****etMRPSize** sets the value of the PROTECTED **MRPSize** property. You can use the **GetUseMRP** value to detect the **MRPSize** value set by the templates, and reset it at runtime via the **SetUseMRP** method.

**Example:**

**IF Access:Orders.GetMRPSize() <; 100 !Currently using a small block size**

** Access:Orders.SetMRPSize(100)      !Use an MRP Packet Size that will**

**                                    !fetch (and cache) 100 rows in a **

**                                    !single request**

**END**
