Create Additional data tab in Rfx/Response/Contract

[Former Member]

Some of you would be interested in knowing how we achieved this. We were trying to add a new tab at the item level which holds Z fields. Now, this is possible via SPRO -Create Table Extensions and Supply with Data . But the limitation is that a table appears in the new tab. Our requirement was to have the new tab similar to that of the item basic data tab.

This was achieved in the following way, I will show below an example wrt to Rfx and the same can be incorporated for Response and Contracts.

Pre-Requisite - Add custom fields through SPRO to the Rfx Item structure and maintain metadata for each field.

1. Create a custom webdynpro componet call Z_RFQ_CUSTOMTAB with your required layout and implement interface /SAPSRM/WDI_L_FPC_CA_DLTS,/SAPRM/WDI_L_FPC_GENERAL and IF_FPM_UI_BUILDING_BLOCK.
2. Create a context node with the structure of the Zfields that were created via SPRO
3. Create an enhancement to /SAPSRM/WDC_DOFC_RFQ_I_D1 and to the used component add  Z_RFQ_CUSTOMTAB.
4. In the layout of the /SAPSRM/WDC_DOFC_RFQ_I_D1 comp, add a new tab to the tabstrip called D1_CUSTOM.
5. Create an overwrite exit to the INIT_TAB method of the component controller of  /SAPSRM/WDC_DOFC_RFQ_I_D1. The logic in this method should be such that you look for the tab D1_CUSTOM , instantiate the Usage of the Zcomp that you added. Create a component using the usage and then initialize the usage
6. In the ONACTIONSELECT_TAB of the view create an overwrite exit , such that you write a code to perform the necessary action when the additional tab is selected.
7. In the window IV_L_FPC_CA_DETAILS embed and emty view and the interface view of Zcomp.
8. Create an outbound plug D1_I_RFQ_CUSTOM of window and then create a navigation link between the plug and 'Default' Inbound plug of interface view as shown
9. 
10. Create a context node in component controller  with the structure of the Zfields, that was created using SPRO.
11. Embed the View of the custom component to window IV_L_FPC_CA_DETAILS.
12. Create a Custom Controller 'CONFIG CONTROLLER’and then right click on it and select ‘SET AS CONFIG CONTROLLER’ to convert it to configuration Controller. 
13. Create a Context ‘USAGE_DEFINITION’ in CONFIG_CONTROLLER and map it to your View Controller because the standard code of FPM application  checks this context node of embedded components .Thus create a component configuration for the custom component.
14. In the component controller method WDDOINIT create a task container instance and get the data  from the mapper object using the instance method 'get_current_bo_mapper' into  attribute mo_bom_rfq.
15. Using the mo_bom_rfq in the component controller get all the data to the current view controller.
16. Add the standard assistance class ‘/SAPSRM/CL_CH_WD_UI_ASSIST_DTL’ in custom component as shown below.
17. 

This is all we did to achieve this. I hope this helps you . Please feel free to drop any questions or view with respect to this and I will be more than happy to reply back.
