How to update just modified fields

dn

I am stuck with a problem. I have a table(tmpItem) who is a copy of Item-table.
TmpItem use for Itemimport before I put them into Item-table.

Now I want to update records in Item table with tmpItem-records there data had been changed in tmpItem-record.

I don't what to use Transferfields...because there is risk I overwrite data in Item. IS there any good trick for my little problem?

1. Create a Report, with TmpItem as DataItem
2. Declare Item as record in Global Var
3. At the DataItem's OnAfterGetRecord trigger, do this:

IF Item.GET("No.") THEN BEGIN
  Item.Description := TmpItem.Description
  Item.MODIFY;
END;

(this will change just the Description of Item, you can do so with the any other fields in Item table)

Well..if it only description-field I can use modify. But in this case there are several fields. I use dataport to import data into tmpItem then I have a form that I can correct data I imported and then update fields in Item-table..is I clear?

Then you only need to use the fields which are on your form (and which users can edit):

IF Item.GET("No.") THEN BEGIN 
  Item.Field1 := TmpItem.Field1;
  Item.Field2 := TmpItem.Field2;

  ...

  Item.MODIFY; 
END;
