Use a master-detail relationship between two blocks.

Block A is the driving block and block B has the details. Join then by using the wizard to create a 'relation' from block A to block B.

In When-New-Forms-Instance:

go_block('A');
execute_query;
go_block('B');
execute_query;
go_block('A');

That should retrieve records in both blocks.

Let's get this straight. You have one block A which is based on table X, but you also have fields in the block that you want to populate from table Y, and there is no relationship between tables X and Y.

col_x_1 col_x_2 col_x_3 col_y_1 col_y_2
val     val     val     val     val
val     val     val     val     val

and you want them to scroll up and down together in a multi-row block.

Am I correct?

You have one block A which is based on table X -- CORRECT

but you also have fields in the block that you want to populate from table Y --- WRONG

I do not have any extra fields to populate from table Y, i have only fields from table X, i have to populate records from table Y into these fields itself

Yes, there is no relationship between tables X and Y

i hope i have answered your doubts

I have some common columns in both table X and table Y. so i want to populate these common columns into block based on table X from table Y

this is like pre populating some of the columns and then later user modifies as he likes and saves it into table X

i do not want to create any block based on table Y

Base the block on a view which is table y MINUS table x and then put a check-box on each line. If the user adds the extra data then the check-box is automatically 'ticked'. The user can also manually tick the check-box. When they push the 'add' button, via a loop through the block, all records that have been 'ticked' are inserted in table x.
