Hello all!

In the OCI-Call the system is using a hidden form to transfer parameters.

I would like to change/delete parameter sap-client.

In my case the system is using following parameters:

function renderCatalogFrame()  {

return'<html><head><meta http-equiv="Content-Type"

content="text/html;charset=utf-8"></head>

<body>

<form id="service_form"name="service_form"method="GET"action="https://www.xxx-xxxxxx.de/fis/fisesales/login_oci.htm"target="_self"autocomplete="off">

<input type="hidden" name="sap-client" value="100">

<input type="hidden" name="sap-language"value="D">

<input type="hidden" name="username" value="XXXXX">

<input type="hidden" name="password" value="YYYYY">

<input type="hidden" name="~OKCode" value="ADDI">

<input type="hidden" name="~Caller" value="CTLG">

<input type="hidden" name="OCI_VERSION" value="4.0">

<input type="hidden" name="OPI_VERSION" value="1.0">

<input type="hidden" name="returntarget" value="_top">

<input type="hidden" name="HOOK_URL" value="http://XXX.XXX.XXX:8000/sap/sapsrm/inbound_hdlr?CODEPAGE=utf-8&TARGET_URL=http%3a%2f%2fXXXX.XXX.XXX%...">

<input type="hidden" name="CATALOG_URL" value="https://www.xxx-xxxxxx.de/fis/fisesales/login_oci.htm">

</form>

<script language="Javascript">document.getElementById("service_form").submit()</script></body></html>';}

 

The vendor is also using SAP but with sap-client 001.

Unfortunately the client is transferred as a parameter and therefore client 100 is used for logon.

I was not able to find (debug) the coding where the parameters sap-client and
sap-language are added.

Where are these parameters added?

Is it possible to change the logic? (not to add a parameter or to change the
parameter).

Thanks in advance for all your inputs!

Stefan

Hi,

check your config

SAP Supplier Relationship Management->SRM Server->Master Data->Content Management->Define External Web Services (Standard Call Structure)

additionally you may implement BADI BBP_CAT_CALL_ENRICH

Hi Konstantin,

thank you for your reply.

The parameter sap-client is added by the system. It is not a parameter within "define external web services".

Within BADI this parameter is still not added by system.

Therefore the BADI can't be used.

Yapp, sorry, it's from the system.

Try to set a breakpoint in the method /SAPSRM/CL_CH_WD_OUTBOUND_HDLR->IF_HTTP_EXTENSION~HANDLE_REQUEST - it generates HTML code for catalog frame.

The parameters are created a little before the call to the outbound handler. However if you remove the parameters in there they don't show up. So I guess an overwrite exit there should work (parameters are retrieved somewhere in the middle of the RENDER_CATALOG_REDIRECTION method - so overwrite that one).

Regards,

Robin

Thanks to Robin and Konstantin I have implemented following solution:

In Customizing of "Define External Web Services" I've added the parameter SAP-CLIENT with the client number of the vendor system. Thus there are two hidden parameters SAP-Client. One with the client of our SRM system and the one of the customizing.

In an enhancement of class /SAPSRM/CL_CH_WD_OUTBOUND_HDLR I determine if there are two hidden parameters SAP-CLIENT. If yes I overwrite the first with second.

Class: /SAPSRM/CL_CH_WD_OUTBOUND_HDLR

Method: RENDER_CATALOG_REDIRECTION

Enthancement before endmethod:

data: LT_MATCHES type STANDARD TABLE OF MATCH_RESULT,
         LR_MATCH_1 type REF TO MATCH_RESULT,
         LR_MATCH_2 type REF TO MATCH_RESULT,
         L_MATCH_COUNT type i.

find ALL OCCURRENCES OF '<input type="hidden" name="sap-client" value="'

       IN cv_html

       in CHARACTER MODE

       IGNORING CASE

       MATCH COUNT L_MATCH_COUNT

       RESULTS LT_MATCHES.

if L_MATCH_COUNT EQ 2.

   read TABLE LT_MATCHES index 1 REFERENCE INTO LR_MATCH_1.

   read TABLE LT_MATCHES index 2 REFERENCE INTO LR_MATCH_2.

   replace SECTION offset LR_MATCH_1->OFFSET length 49 of cv_html
                with cv_html+LR_MATCH_2->OFFSET(49)

                in CHARACTER MODE.

   replace SECTION offset LR_MATCH_2->OFFSET length 51 of cv_html
                with ''
                in CHARACTER MODE.endif.

endif.

Hi,

please check Function Module /SAPSRM/CLL_WSI_CALL and in there doubleclick on the map_cust_to_name_value form in here search for the sap-client string.

It looks like it is not that easy to get rid of it. Maybe create an implicit enhancement in the map_cust_to_name_value and remove those 2 entries again?

This function is actually called from class /SAPSRM/CL_CH_WD_NAVI_SERV and method /SAPSRM/IF_CH_WD_NAVI_SERV~LAUNCH_CATALOG

I don't think the BBP_CAT_CALL_ENRICH is going to be of help here as it is called later and doesn't have those 2 values available.

Regards,

Robin

Hi Robin,

thank you for your reply.

I've set a break-point and deleted the field sap-client in debug mode.

But the hidden parameter sap-client is still in my trace of the OCI-URL call.

Therfore it is not the right place where the hidden parameters are added.

Regards

Stefan
