Purpose Help you to understand the allocation of the external programs registered to the Gateway of an SAP instance. Overview This page contains information about the allocation of external programs in the Gateway of an SAP instance, aiming to demonstrate the analysis behind their usage and common errors. RFC Error 'Timeout during allocate' The most common error related to the allocation of Gateway registered programs is the error 'timeout during allocate'. This error is described in the SAP Note in details.

With the command rfcexec -r -aprogram_id>-g -x you can register a RFC program at the SAP Gateway.When I enter this command at a command prompt in. 'RFC Server Program' Registration on SAP. We will see how we can register a “RFC Server Program” on our SAP system. We can register an RFC Program via SAP.

One of the possible causes mentioned is the fact that the affected program is not registered multiple times in the Gateway and the only registration performed is already in use, causing the below timeout if the program is attempted to start more than once. The analysis behind this aspect of the 'timeout during allocate' error will be explained in details in the next chapters of this wiki page. Facebook Password Hacker V2.5. Analyzing the RFC Destination Configuration In order to check how exactly the RFC destination for this program is configured, you will need to access transaction SM59 and open the RFC destination responsible for starting the TP you want to analyze (ExampleWiki as per the above image). After selecting the RFC destination, in the Technical Settings tab as per the image below, one specific Gateway to communicate with the External Server can be defined in box 'Gateway Options'.

Gateway Options is Specified in the RFC Destination If the Gateway Host and Gateway Service are specified in the Gateway Options box as per the below image, it means the communication with this External Server where this External Program is started will only be performed by the defined Gateway (sapgw00 running in the host hostexample1). Gateway Options is Not Specified in the RFC Destination If the Gateway Host and Gateway Service are not specified in the Gateway Options box as per the image below, the local Gateway will communicate with the External Program (E.g. Application Server where the user is currently logged on or where the job is running). In this scenario, the External Program has to be registered in all the instances of this SAP system, otherwise the error 'program not registered' will be triggered as per the SAP Note.

Gateway Registrations of the External Program The next step of this analysis which follows the analysis of the RFC destination is the analysis of the Gateway registrations of this External Program. For this, you must access the transaction SMGW and use the meny GoTo, selecting the option 'Logged on Clients'. This is shown in the below image.
