In case of Asynchronous (aRFC) call, the system passes the control back to the calling program immediately. The RFC call is executes in a different work process or in a new internal session. aRFC calls are of two types: - Asynchronous call without response
- Asynchronous call with response
In case of aRFC, you can ask you calling program to wait until it receives some response from the calling function module. You can then process the result of the aRFC call.In case of aRFC without response, any error message or system exceptions from the executing function module cannot be handled in the calling program. The processing of a aRFC without response is shown in the below diagram:

Synchronous RFCs (sRFC) are most commonly used RFC. sRFC is ideal choice when you want the results of the function module immediately after the call. The sRFC call is passed immediately to the remote system and the caller program is halted until the response from the function module is not received. The function group of the function module is loaded into the internal session of the target system and the context is retained until the RFC session is closed. Thus, if repeated calls of the different function modules of the same function group and destination are made, then the global data of the function group can be accessed collectively. This makes an sRFC a great choice when data is repeatedly required from a target system.

An RFC is used when you want to access (read / write) data from remote systems. Within SAP landscapes, RFC continues to serve as basis of nearly all major integration points like: ALE, IDocs, Portal, MDM etc. The main task of the RFC run time is to facilitate the execution of function modules in remote systems. This remote system could be SAP system or an external program linked with one of the SAP-supplied RFC connector libraries. One of the first things that you need to understand to work effectively is how RFC calls are actually communicated and executed. The figure below illustrates this. The communication cycle begins with a work process that generates a RFC request.

The optimization function in MRS enables the scheduler to create optimized schedule for their technicians. The strategies of optimizer can be configured. Thus the optimizer can be used to create schedules such that: Travel time is minimum OR Utilization of resources is maximum OR Overtime for technicians is minimum OR any other strategy which is suitable for the customer.
The Relevant data for Optimizer: Technician: The availability information of the technician. His working times, breaks etc. The starting location of the technician and his qualifications.
Orders: The location of the customer (address), the time window where the operation can be executed, the required qualifications to complete the task.
The optimizer takes this data from MRS and will propose an optimized schedule which will result in minimum cost.

There are 5 types of RFCs. Each of these types is used for a specific purpose and has a unique role. The five types of RFCs are: - sRFC - Synchronous RFC
- aRFC - Asynchronous RFC
- tRFC - Transactional RFC
- qRFC - Queued RFC
- pRFC - Parallel RFC

A new release of MRS (MRS 700) is available since November 2009. Some main functions and features of this release are: - Additional deployment options like:
- This is achieved by decoupling the old Add on into two: Add on for Netweaver and Add on for ECC.
- The NW add on can be installed on any Netweaver platform.
- The ERP Add on can be installed only on ECC 6.0 and required MRS Netweaver Add on as prerequisite.
- Integration with CRM Service Orders
- MRS 700 can be integrated to CRM Service orders.
- MRS 700 Netweaver Add on can be deployed on a CRM instance also
- Support of Multi Back end demand systems
- Demands from multiple PM/CS systems can be integrated into one instance of MRS
- Support of HR Qualifications from c-Pro
- In addition to MRS qualifications, the HR qualifications can also be used in c-Projects Planning Scenario
- Enhancements in MRS Optimizer
- Optimizer provides new logging feature
- Optimizer provides functions to schedule optimization from outside the planning board too.

Lot of customers wonder if they can change the sequence of the resources in Planning board. The standard planning board by default sorts the resources based on their name. However, if you wish to change the sort sequence, then you can do so. There is no customizng option to do that, but a BADI is available that can be used to change the sorting sequence.
