Type of Program

Question

Dear All
WE have a Z Table with 3 primary keys.
The data for this table comes from a Legancy System
in a File.
We need to upload the Data from this File into the Z
Table.
We are planning to design Z program to does the data
upload that will run in both DIRECT and BATCH mode. What type of Data Upoloading will be best:
  1. Direct DB MODIFY(using Stmt MODIFY Ztable FROM itab)
  2. BDC necessary ?
or anyother.
Please advice.

Hi,
Since this is a Z table with simple business logic, I would recommend you to go with the first option: Modify Z table directly, as it's better from the performance point of view, and easier to do.
This option is better because:
1. You don't have to create a dialog program to do it
2. You can use mass insert/update (MODIFY Ztable FROM itab)
If you want to do BDC, then you will have to:
1. You have to create a dialog program
2. You have to create BDC program to batch data
And in terms of performance it's slower than the first option.
