bgRFC - A database commit was blocked by the application

[former_member185171]

Hello,

we configured bgRFC in our system. We use it to launch a external webservice.

In SBGRFCMON we almost always get an error:  "A database commit was blocked by the application".

In SM12 two locks appear : one on BGRFC_I_SERVER_REGISTRATION and one on BGRFC_O_SERVER_REGISTRATION.

In ST22 we have the following dump:

Client.............. 200

User................ "U0000657"

Transaction......... " "

Call Program........."CL_BGRFC_DS_EXEC_INBOUND======CP"

Function Module..... "BGRFC_DEST_SHIP"

Call Destination.... "d11_D11_00"

Source Server....... "d11_D11_00"

Termination occurred in the ABAP program "SAPLHTTP_RUNTIME" - in
  "HTTP_READ_SC".
The main program was "SAPMSSY1 ".

In the source code you have the termination point in line 22
of the (Include) program "LHTTP_RUNTIMEU07".

     id 'RC'                value rc.                   "#EC NOTEXT

When we launch the same function (with the webservice) without using bgRFC - synchronous - everything works fine.

Anyone any idea where we might look for a solution for this problem?

Thanks.

The bgRFC has a commit trap, as commits within bgRFC unit processing are generally not recommended. In case a commit is necessary (as e.g. the implicit DB commit caused by an HTTP call within WS processing), there is an option to switch off the bgRFC commit trap for a specific bgRFC unit. This is exposed via interface IF_BGRFC_UNIT, and e.g. is used by WS for the reason explained above.

So if the bgRFC commit trap is responsible for the dumps, the application has the option either to avoid the commit or switch off the commit trap.

So this is the statement that solves the problem:

gr_unit->if_bgrfc_unit~disable_commit_checks( ).
