Capturing return status from a call to STARTRFC from a shell script.

Hi All

I am trying to use startrfc to integrate a Unix (Solaris) batch process with SAP. I want to determine whether an SAP user exists.

Here is the command as run in the Unix shell: -

startrfc -t -3 -h ourHost -s 01 -c 550 -l EN -u SAPuser -p secret -F BAPI_USER_EXISTENCE_CHECK -E USERNAME=testSAPuser

This command always exits with a status of zero, whether or not the user exists. (With the -t flag) It creates a file, dev_rfc and a second file of the form CPICTRCnnnnn. However there is no output to stdout, irrespective of whether testSAPuser exists.

Can I force this utility program to write its output to stdout instesd of writing it to a file? How?

Alternatively can I force the utility to write its output to a specific (named) file instead of writing to dev_rfc?

Thank you for your attention

Hi,

You could create an RFC in SAP and put your BAPI function, an the result into a table parameters:

- use -T parameter to get the table

- use w to set your file

Example:

startrfc -E PEBELP=00010 -t -d AR1 -h S01AZ03A01 -s 10 -g S01AZ03A01 -x sapgw10 -u LOLA -p flores -c 130 -l EN -F Y_RFC_EXAMPLE2 -T RESULTADO,250,w=outputname.txt

Explanation of parameters:

-T <table name>,<width>,[r=<file>][,w=<file>]

Where <file> is a path name to read from (r) or write to (w) the internal table. If <file> is -, stdin or stdout is used.

Example of Y_RFC_EXAMPLE2

FUNCTION Y_RFC_EXAMPLE2.

*"----

""Local interface:

*" IMPORTING

*" VALUE(PEBELP) TYPE EBELP

*" TABLES

*" RESULTADO STRUCTURE TAB512

*"----

DATA fecha(10).

DATA wa TYPE string.

WRITE sy-datum TO fecha.

CONCATENATE pebelp fecha INTO wa SEPARATED BY '/'.

ds_rec 'sample' wa.

append wa to resultado.

ENDFUNCTION.

Hi Johan

Thanks for your thoughtful answer. I am not a BAPI programmer and I would prefer, if possible, to avoid the direction you are suggesting.

It is clear from other posts in this and other fora that BAPI_USER_EXISTENCE_CHECK returns information to the calling process. My project really requires that this returned information is written to STDOUT so that I can capture it in a unix shell script.

The source code for startrf is available as part of the SDK. Another way of dealing with this problem may be to write a small mod to the startrfc.c program. I am more comfortable in C than in ABAP.

Anyway, thanks once more for your suggestions.

Cheers

Stephen

Hi Vjay

Thanks for your response. I assume you mean "which version" of SAP. R3 is the answer if I am right.

Cheers
