maximum RFC connections in RFC

Hi all,

i am facing a problem while trying to send lots of messages from R3 to XI via RFC Sender Adapter:

See the SM21 log in sender system: (R3):

Communication error, CPIC return code 027, SAP return code 677

> CPI-C function: CMINIT(SAP)

anf if i go to the work process log in sm50 (still in R3):

  • LOCATION SAP-Gateway on host sp-xxx / sapgw01

  • ERROR timeout during allocate of registered program

  • TIME Tue Nov 18 10:57:12 2008

  • RELEASE 700

  • COMPONENT SAP-Gateway

  • VERSION 2

  • RC 677

  • MODULE gwr3cpic.c

  • LINE 1847

  • DETAIL TP ZRFCSENDER_xxxxx init/busy for more than 60 sec

  • COUNTER 4477

However, nothing is shown in sm21, neither in SM50...

The program ID is registered in SMGW and the maximum RFC connections in RFC_Sender_Channel is set to 100 (although i think that the limit is 50)

When the customer executes the interfaces, they get following 30% with this error (up to 3000 messages in 2,5 hours)

Could you please help in sorting this issue out?

Thanks a lot in advance and best regards,

david

    it was a matter of the gateway, we needed to set the gw reg program parameter to a higher value!
