problems in n level workflow

Hello,

I know of the following problems in normal functionalties of N level workflow. Could you please let me know if you have faced anything different than this ? This is needed in the design and estimation stage of the workflow.

1. The ‘add approver’ functionality does not work

2. The BADI of approver determination is NOT called after every approval

3.1 The rejected items get carried forward.

In the shopping cart approval, the creator receives a work item to accept the changes (in authorization level 1 and higher, the creator has the option to change the shopping cart). However, if you choose 'Accept changes', the system passes on the shopping cart without deleting the rejected item(sapnote744273)

3.2 The restart of workflow on rejection functionality provided in sap notes does not work

thanks
