Hello Aditya,
Answering your questions one by one...
1. Can we change the Folder name "Technical Details"?
Yes , we can. This is set via the code in class /SAPPSSRM/CL_TECHBID_CFOLDER method /SAPPSSRM/IF_TECHBID_CFOLDER~CREATE_BI. In this there is a call
CALL FUNCTION '/SAPPSSRM/META_CREATE_COLLAB'
EXPORTING
i_folder_name = /sappssrm/if_tendering_const=>gc_cfx_name
IMPORTING
e_faultstring = lv_cfx_faultstring
e_collaboration_id = e_collaboration_id
e_public_area_id = e_public_area_id
e_root_folder_id = e_root_folder_id
EXCEPTIONS
no_logical_system_defined = 1
OTHERS = 2.
The constant /sappssrm/if_tendering_const=>gc_cfx_name is the "Technical Details" is the name and you can change the name by performing the enhancements here.
2. Do you need administrator to provide access to folders for bidder?
No certainly not required. Generally at RFX Response creation system will provide read/write authorizations to the bidders for specific folders. This is handled in the code and you would not require an Administrator intervention here.
3. Bidder having access to other folders?
This is a result of your manual assignment. The standard code ensures none of this happens.
Thanks and Regards,
Veera
