Hello Everyone,

We have a requirement to call a OCI External Catalog in ME51n Transaction in ECC, that is working fine.

Now we need to create a Web dynpro ABAP Application which performs the Task of ME51n Transaction along with OCI Integration.

So far i have create a small Web dynpro ABAP application to check does OCI Catalog can be integrated in ECC using web dynpro ABAP.

My Screen Consit of a single Button UI, on click of the button i am calling the External Catalog, from the catalog i select all the materials and click on submit finally we need to bring all the selected materials to get displayed ina table.

Half of the Development is done i.e i am able to call the catalog but not able to receive the selected materials.

following are the details-

1. I check in SRM first how the Ctalogs are been called, i found 2 Services responsible for the same in SICF transaction -

Inbound HLDR and Outbound HLDR which uses handler class as SAPSRM_CL_CH_WD_INBOUND_HDLR and SAPSRM_CL_CH_WD_OUTBOUND_HDL, so i copied the same classes into ECC and created the same SICF Service.

Contn. in next post...........

2.In my Web Dynpro ABAP application i have a Inbound plug in my window in the handler method of the inbound plug i fill a table lt_parameters of TYPE tihttpnvp, it has 2 columns name and value

In this table i fill following entries-

Name-CATALOG_URL

Value-https://XXXXXXXX.com/invoke/BVProcess.SAPOCI/processCatalogRequest

Name-USERNAME

Value-XXXXXXXX

Name-PASSWORD

Value-XXXXXXXX

NAME = 'HOOK_URL'.

VALUE = 'http:/XXXXX.hostederp.local:8000/sap/ZOTC_CAT/Zinbound_hdlr'."?TARGET_URL= {Appdress of the WDA Apllication}

NAME = 'OCI_VERSION'.

VALUE = '4.0'.

NAME = 'OPI_VERSION'.

VALUE = '1.0'.

NAME = 'returntarget'.

VALUE = _top

also in this inbound plug handler method i fill a lv_url variable of type string with-

lv_url = 'http://XXXXXX.hostederp.local:8000/sap/ZOTC_CAT/Zoutbound_hdlr?sap-client=100&sap-language=E'.

3. finally from the handler method of the inbound plug i call a Suspend plug p[assing the above two variables i.e

lt_parameters and lv_url.

wd_this->fire_zw_suspend_plg( url = lv_url i_parameter_tab = lt_parameters ).

4. Using above i cam able to call the catalog and select the materials.

5. Now if i Finally clcik on submit on the catalog it should return the materials to the WDA Application.

For WDA Application to accept the Materials i have created a resume plug in which i am using -

wdr_task=>server->request->get_form_fields( CHANGING fields = lt_fields ). to get all the selected materials into lt_fields.

6. But unfortunately i am unable to receive the selected materials in lt_fields.

I think i am missing something in Hook URL or some other parameter.

Please help, ur comments and suggestions are welcome.

Regards,

Akash Rana
