Accessing the Chain-Liability
Area Menu 
To facilitate the use of the chain liability functions, the chain-liability specific transactions are made available in a special area menu called WKA_MENUE. This menu consists of the following three transactions:
· WKA01 – Change Payment Block and Payment Method
· WKA02 – Document Flow of Purchase Order Line Items
· WKA03 – Check Expiry Dates of Certificates
This chain-liability area menu is not included within the SAP area menu. The chain-liability area menu can either be included as a personal favorite or within the user menu which can depend on the role of the user.
Including the
chain-liability area menu in the SAP area menu is also possible, but will lead
to a customer modification.
To maintain your area menu, call transaction SE43 where you can carry out all the required activities.
