All I want to make monthly transaction bvy giving month n yr n tag_unit in control block. If the user has already entered the data of certain record of specific month and year, I don’t want that record to come in the block. How I m going to write the query for that and how I m going to join two data blocks.
file is attached

Hi insomniius

1.To join the blocks Try to create a relation between both the
data blocks.
2.Use a pre query trigger in control block and validate whether
month,year,unit are null. if they are not null then pass that data to where clause

where month not in(:control.month)
and year not in (:control.year)
and unit not in (:control.unit)

Try to pass this where clause dynamically using
Default_where (built in)

Hope this will be helpful

Thank You
