process chain...

Hi All,

I have a small question, I have bw system 3.5 in which the implementation was taken place. The client then replace that system since the operation and process was slowly get into failure. Till last year and for some areas till 2011 the entire process was smooth.

My question is as mentioned above on same system i have to re initiate the process checking from process chain,loading etc.

I have observed in finance module the delta upadates were upto 2012.

So in order to begin in same scenario for process chains which area i should start with.

Please give me good conceot

Thanks
