| Short description: Max. number of internal asynchronous messages |

------------------------------------------------------------------------
| Parameter description : |
| ----------------------- |
| An SAP work process (WP) can receive various messages: |
| - Requests from a SAP GUI |
| - Requests from an ABAP program (RFC requests) |
| - Requests from other WPs / application servers (messages) |
| - Results of outstanding calls (enqueues, RFCs) |
| |
| The process is always that a message leads to the activation of the |
| work process, this performs an action, a result may be returned, and |
| the work process then waits for a new message. |
| |
| |
| However, there are also cases in which additional messages are |
| sent during the processing of a message, and it may be necessary to |
| wait for the responses to these. Examples of this are enqueue or |
| creating an RFC connection. In particular, in the case of |
| asynchronous RFC, the RFC responses can arrive at "any" time. |
| |
| However, since the work process cannot process every type of message |
| in every situation, each SAP context has a local queue. The messages |
| that cannot be immediately processed are temporarily stored in this |
| queue. The parameter rdisp/max_arq defines the size of this local |
| queue. |

| Other Parameters Affected or Dependent: |
| |
| If there is a very high amount of RFC load on an application server, |
| and parameter %%rdisp/max_comm_entries%% was increased because of |
| this, we recommend that you set rdisp/max_arq to the same value. |
