Obj Save nulls the column
If a table has 10 columns and the values for 4 columns are modified using Property-Set.If Obj-Save is called to update the table, the other columns are updated with null values.Is there a way to avoid overriding the other columns in obj-save.

Can it be done without browsing and getting all the columns, I don't want to go for Browse approach becasue the table might have millions of records, Since I have the key of the row to update,I want to do it without browsing or opening the record.
Yup the existing data are set to null. I traced and got the query. It is trying to update all the columns in the table with default null values for the ones which doesnt have value in Obj-Save step page.
If you are browsing to get the rows from your table, then perform an Obj-Open (or its equivalent) for each instance, set the properties that you want to update and then perform a save on the step page where you have opened your instance and updated.
yes that is what I am currently doing, I am using an obj-open and then setting the necessary columns and doing a save. But since I know the record to be updated, I was wondering if we can do without an Obj-Open.
When you look at the properties on the work object that correspond to the columns getting nulled out, are they also null or is there a value that is written to the blob? The exposed columns should contain the same data as the blob, if they don't there is something wrong. If they do, the question then becomes what is nulling out the value (and should it have nulled out the exposed columns earlier, or is the change recent)?
It is not a work object table. I am trying to update few columns in data table(exposed columns). Since Obj-Save nulls out any column not available in the step page, I have used an Obj-open before the save to retain the existing data.
