A function needs to be developed which will return a boolean value. Depending upon the return value of this function it will be decided whether the link of another document should be visible to the current logged in user or not in any asp page.
Include a column Manufacturer Lot No in GRN entry. That column should be editable and will bring the value from column of inst_lot_id of table t_inv_stock_transaction.
