Batch program

Question

HI,
A batch program is needed.This batch program will be scheduled as a batch job.
It should query table say 'A' depending on two mandatory and one optional parameter.There is only one primary key in table 'A 'and it is an optional parameter.This query would give a list of say all sales orders(optional paramter).Using this list of sales orders, I would then need to query another table say 'B' where sales order is a primary key along with material number.Now for sales order S and material M1 I need to update a certain field in' B'.For same sales order S and material M2 I need to update a certain field in 'B'.Also I need to update a field in table C where there are four key fields and sales order and material are two fields.The business rules for update need to be taken from a config table.
How can I ?
(A) Do the process in the backgroung as a say BDC /batch input without end user intervention
(B)Create a new config table and maintain the rules there.I know the rules.
Thanks for your help in advance !!

Hi,
you could update the tables directly - but then you / the batch report would be fully responsible for the correct business logic, not only the additional customer requirements, but also all standard logic -> usually a task to big.
Instead it's easier, safer, recommended to use standard interface to update tables (as long as we don't speak about append fields.
In your case BAPI_SALESORDER_CHANGE might give you the possibility to change the values - but you didn't describe the fields / tables good enough for a good help. Also call transaction would follow the business rules (when you add the customer logic with user-exit or field-exit...).
I hope I got your problem, your description was a little bit ... around some corners?
