Hi Imtiaz,
Thanks again for your reply.
gw/cpic_timeout is dynamic and I have increased to 40 from 20 , and gw/max_conn is already set to 4000.
To isolate the problem, I have also removed load balancing with the connection, now directly with CI only. This is production, so I have to wait till next data load.
I will update with the result
Thanks
Al Mamun

Alberto Marchan

Hi Alberto,
CPIC is a type of user (Communication..) used for certain calls.
Has your BASIS team applied all the patches and related system settings?
SOrry, I do not remember the exact answer to the issue.
But I do remember that it is a system setup issue.
Good luck, BB

CPIC-CALL Transaction program not registered Error while creating RFC Desti

Hi All,
I am trying to create a new RFC Destination.
Details I have provided are..
1.RFC Destination Name
2.Connection Type - TCP/IP
3.Description
4. Activation Type - Registered Server Program.
5.Program Id.
6. Gateway Host and Gateway Service.
But When I Test the connection, I am getting the following error.
" program xyz not registered / CPIC-CALL: 'ThSAPECMINIT'# Transaction program not registered"
However I was able to create and connect RFC Destinations successfully previously.
I am not SAP guy. Could someone help resolve this issue.
Thanks,
Phani

hi Sekhar,
I request you to please help me out in this issue. I am getting similar kind of problem. I am trying to replicate the customer from CRM to R/3 and i get a bdoc message in SMW01 that "RFC connection failed please press the save button again".

Error when opening an RFC connection (CPIC-CALL: 'ThSAPOCMINIT' : cmRc=2 thRc=679

Hi,
We update the BW landscape for version 7.4 suppport package 4 (whitout HANA).
We use a external system connection to extract data from a SQLServer database (Microsoft Connector 1.1 for SAP/BW)
In the previous version (BW 7.0.1 SP 10) run correctly, but now is in error.
Below the BW error log:

Hi Bruno,
We were able to resolve the issue. SAP RDS is assisting us with our upgrade and one of their consultants gave us this fix/workaround.
Edit and add an entry into P:\usr\sap\<SID>\DVEBMGS00\data\reginfo.dat on your BW host server.
Below is the entry I added.
P TP=<NAME OF PROGRAM ID> HOST=<remote hostname where you creating the RFC to> CANCEL=<remote hostname> ACCESS=*
P TP=CTSAPNPSCI_PORTAL_FPS HOST=ctsapnpsci CANCEL=ctsapnpsci ACCESS=*
Then in BW system goto smgw > goto > Expert Funtions > External Security > ReRead ACL (N) & Globally
I hope that this works for you.

some of the posts on forum suggested i should try from same domain i tried but in vain, then i updated the SAP kernel from 7.01 sp 14 to sp 55. but i am still facing the problem.
i created this system recently using system copy based upon export image of a system (ABAP stack ) but using ABAP+Java during export process (by mistake). then we tried to build system using import (ABAP stack only i know its weird but its up and running). I assume we should have builf export imgae using ABAP method but some how due to lack of time we proceeded this way.
The main problem i see is TP RFC . The output from prgram RSTPTEST is as below
everythign is fine except below entries

RFC link and Offline Call shws me the same error as RFC ping. and there is no output from tp version and DB connect.
Can anybody please help me on the same.

STMS error - Timeout during allocate / CPIC-CALL: 'ThSAPCMRCV'

Dear Experts,
We are facing issue in releasing or importing TRs.
1.When releasing TRs in DEV server, it is showing error message "Could not start control program TP" on status bar. But repeating the same process went successful.
2. While Importing TRs into QAS, at the time of refreshing queue/adjusting import queue, it pops-up error " timeout during allocate / CPIC-CALL: 'ThSAPCMRCV' .But after repeating same process, TRs were impoted successfully.
We had performed the following in DEV & QAs:
1. Upgraded kernel to patch level 137.
2. After that replaced TP & R3trans with latest patch levels 169.
3. Re-configured STMS
4. Restarted Server.
Also checked,
(i). Report RSTPTEST in se38- sometimes successful; sometimes error :"timeout during allocate / CPIC-CALL: 'ThSAPCMRCV' (ii). RFC "CALLTP_WindowsNT" in sm59 Connection is OK.
Please help.
Thank you in advance.
Regards

Hi,
Check below link if it helps:
Re: STMS
Pls also check below things :
- check that the "Gateway Options" are maintained in SM59 and the sapdp00/sapgw00 are maintained in the etc/services files. SAP Note 52959
- Please check SAP Note 773830 if you are on a cluster environment.
For the error regarding timeout during allocate / CPIC-CALL: 'ThSAPCMRCV' please check SAP Notes 581509, 566566.

Screen painter error: EU_SCRP_WN32 : timeout during allocate / CPIC-CALL

Dear all
When i using SE51 to open any screen , the screen painter can't give me the graphical layout editor and shows the following message:
EU_SCRP_WN32 : timeout during allocate / CPIC-CALL: 'ThSAPCMRCV'
Message no. 37033
Anyone knows what is the problem?
Detail information :
SAP GUI Version : 710 for window
Fatch Level : 11
thanks for your input.

Dear All... I had same problem for many mounths... My solution has been the "NAME" of my computer. My name contains a special char ( ì ) and the server didn't answer at my "request" to launch the screen painter SAP.
So try to change your "PC-Name" without special char (ex: "office") and try again to launch the Screen Painter.
I'm sorry for my bad english and i hope this reply will be usefull for You.
Paolo
ITALIAN VERSION:
Ciao a tutti, io ho avuto questo problema e non sono riuscito a trovare risposta; nelle innumerevoli ricerche in rete, con colleghi e persone più esperte di me sono riuscito a capire che lo Screen Painter di SAP in realtà è una sorta di "richiesta" che viene fatta al server. Se il Nome del PC contiene caratteri speciali, il server sembra non rispondere e quindi si va in timeout.
In pratica ho risolto formattando il PC ed in fase di re-installazione de S.O. ho dato come nome solo il mio nome di battesimo ed ho risolto. Ho dovuto effettuare un Format perchè nonostante avessi cambiato il nome del PC da schermata di Windows, la modifica non sembrava essere effettuata correttamente.
Ho testato questo problema su diversi computer e il problema si è sempre risolto in questa maniera.
Spero che questo contributo sia utile a tutti Voi.
Rimango a disposizione per qualsiasi chiarimento.

Issue between BW Query and Web Intelligence - CPIC-CALL 'THSAPCMRCV'

Hi all
Receiving the current error when trying to connect BW to BusinessObjects via SAP Integration kit
The error occurs whenever I put more than one dimension in the query. If I put just one dimension, the query will run successfully. I've checked and implemented SAP Note 1032461 but it does not seem to have solved the issue.
BusObj version is 3.1 Service Pack 3, Fix Pack 3.4
Business Warehouse version is 7.01
The complete error message is
A database error occured. The database error text is: Failed to execute MDX query. Reason: Error occurred when starting the parser: timeout during allocate / CPIC-CALL: 'ThSAPCMRCV'. (WIS 10901)
Thanks for your assistance.

Hi Ingo.
Thanks for your assistance, I double checked the work our Basis Guy did and he installed the Unicode 32bit pack, rather than the non unicode 64 bit pack. It now works.
Thanks very much for your help
David.

Can't release transports - timeoutduringallocate/CPIC-CALL

When I try to release a transport, I get the message:
>Could not start transport control program tp (TP608),
>There was an attempt to start the transport control program tp using the local RFC interface. An error
>occurred here.
>
>Error code: 4
>RFC error text: timeout during allocate / CPIC-CALL: 'ThSAPCMRCV'
It suggest running SMGW, but that gives me the message. Gateway monitor is deactivated
I also ran the check transport tool:
>timeout during allocate / CPIC-CALL: 'ThSAPCMRCV' : cmRc=20 thRc=456#Time out during connection setup (check that partner exists
SM21 shows:
>Communication error, CPIC return code 020, SAP return code 456
> Conversation ID: 05807275
> CPI-C function: CMSEND(SAP)
>Tp call failed (RFC RC = 4: RFC message = timeoutduringallocate/CPIC CALL:'ThSAPCMRCV':cmRc=20thR...)
456 means: Timeout during conn. setup
I've upped the timeout of gw/cpic_timeout to 2 minutes, and still get the error.
In SM59, the RFC trace shows:
>**** Trace file opened at 20090511 212541 Pacific Daylight Time, SAP-REL 700,0,1

So, I've looked at the destination CALLTP_WindowsNT - it exists in SM59. I checked the program location is correct and exists - and I ran it in a windows console. I did a connection test in SM59 and got:
>timeout during allocate / CPIC-CALL: 'ThSAPCMRCV' : cmRc=20 thRc=456 Timeout dur
>ERROR: timeout during allocate
>LOCATION: SAP-Gateway on host SecureBI / sapgw00
Any suggestions?
thanks
matt

Hey, nice to see you are doing some real SAP work too, and not only moderating here (just kidding - keep up the good work).
I suggest you check first if your gateway is up and running. Check the dev_rd trace file for errors (either in SMGW, ST11 or directly in the work directory). Try to telnet to your gateway :
cmd> telnet host1 sapgw00
Trying 10.2.0.1...
Connected to host1.
Escape character is '^]'.
Regards, Michael
Edit: you can also check if you see the process gwrd(.exe)

SAP ERP - CTS and Backup error CPIC-CALL: 'ThSAPCMRCV'

hello All,
I have some issues with transport system and when I try to schedule backup jobs in my ERP system. When I try to reconfigure my transport system the following message:
Could not start transport control program tp
Message no. TP608 Diagnosis
There was an attempt to start the transport control program tp using the local RFC interface. An error occurred here.
Error code: 4
RFC error text: timeout during allocate / CPIC-CALL: 'ThSAPCMRCV'
Meaning of the error codes:
03 RFC system failure
04 RFC communication failure
System Response
The function terminates. Details about the error can be found in the trace file of the Gateway Monitor (SMGW).
Procedure
Contact your system administrator or use report RSTPTEST to localize the error. You can then execute the command again.
Al ejecutar el reporte RSTPTEST se presenta:

I executed the report RSTPTEST   and the result was successful.
Another error is generated when I try to schdule the backup jobs in DB13:

Error               : System Error
Error Message       : timeout during allocate / CPIC-CALL: 'ThSAPCMRCV' : cmRc=20
I checked the connection between SAP and DB and is OK. I found in some forums and SAP Notes that this error can be fixed with a kernel update, so I updated the SAP kernel, TP and R3trans files but the error continue.
I don't know what more I've to check, so I need your help to solve this issue.
Thanks
HEPC

hello Michael,
I could fix the transport system, was a network issue, but the DB13 error continue, now when I test the DB connection the following error is show by the PRD system.
Connect. test with "dbmcli db_state"                         Unsuccessful
I decided to close this message and open another in MaxDB forum.
Thanks

Max no of 100 conversations exceeded / CPIC-CALL

Hi All,
There are more than 4000 messages in SMQ2 Tcode and when we checked the SLDCHECK we got this error-:
RFC ping returned exception with message:
max no of 100 conversations exceeded / CPIC-CALL: 'ThSAPCMRCV' : cmRc=17 thRc=45
After increasing the value for parameter CPIC_MAX_CONV 1000 it started working but after 1 min SLDCHECK again gave the same error.
We have already checked and implemented the SAP Note :316877.
I have one doubt this Note says that CPIC_MAX_CONV value should be 5000,is it really required?
I have checked the SLDCHECK with value 1000 for CPIC_MAX_CONV .
Pls suggest the solution.
Regards,
Prashant
Edited by: Prashant Shukla on Jan 27, 2009 12:50 PM

CPIC_MAX_CONV value should be 5000,is it really required?
No, this is not mandatory. You should set it as per the load on your system.
What is the error when you perform SLDCHECK?

hi
Check SAP notes ]<a href="https://websmp203.sap-ag.de/form/sapnet?_FRAME=CONTAINER&_OBJECT=012006153200000084722004">722514</a> and <a href="https://websmp203.sap-ag.de/form/sapnet?_FRAME=CONTAINER&_OBJECT=012006153200001357592002">532918</a>
This problem occurs because the RFC communication partner cancels the connection to the SAP back-end system.
The error may also occur if an SAP router or a firewall between the RFC back end and the RFC program interrupts the connection because of a power failure or because a timeout has been exceeded.
Solution
You can use note 532918 to analyze the problem and determine why the communication partner for the back-end system no longer answers the RFC requests.
hope that helped!
