Hi
Common sense will be there for every body even for my Client too.They are using SAP from the past 5 years because they believe in SAP. That is the reason they are continuing further--
If they are using SAP from past 5 years then I am surprised why would they ask such explanations? What have they learnt from fast year experience with SAP? I used such words with you because we are all SAP guys here and we understand and know SAP better than clients or users and now it is upto you how efficiently you handle them and I believe this is communication/convincing power which every consultant must have.
Even i am also Trying to think little logical--why it cannot be retrieved.
As I already told you that field REF_KUNNR is not there in any data base table so its useless to search any information for old customers in SAP unless you have done some modification and that would work for new customers not for old ones.
You managed the situation by creating one customer before your client and they saw that its working fine so they assumed that it was working fine in past too and this is again trust and believing in SAP. You already did that what I suggested you but with different words and strategy. This is all about understanding.
PS: When we post a thread here in SCN, it becomes public and any member can comment on this based on his knowledge or experience. Agreeing or disagreeing with someone's opinion is always there but no one here is hijacking any discussion and this is the way we share knowledge and we learn new things.
