Update rules:Conditional update

Question

Hi
Can we use update rules to conditionally update fields in a record.
By condtionally i mean to say that, from a delta record ,can we have some conditions so that based on that, we will update the fields.
Like based on conditions , we will update only selected fields .Is it possible using
update rules or by any other ways at the BW side.
Regards

Hi Dash
Please have a look at the req. below.
We have a scenario in which we have values for few fields when a record is created. But once the record is updated ,we will lose those by overwriting that with initial.But we need to maintain those values for those fields to be retained in the BW system in the delta update.
Eg. We have 50 fields in the extract structure , and for fields X,Y we have values 'S1','S2' respectively(char values ) when a record is created,but when the record is updated in CRM system,it will be overwritten by initial.So in the available delta record ,we don’t have the values 'S1','S2'.But in the BW system, we need to have the same      original values instead of initial value in the delta record.
Can you suggest a solution to maintain the original values ?
Does BW support conditional update,like based on condition check,update the some selected fields of the record instead of updating with all the fields in the delta record?
