And at the same time if I save the purchase.dbf record  I want to replace the item purchase_qty in purchase.dbf and stock.dbf in resected fields... how I can do these? I don’t prefer look up table or line-item entry or edit. But the other-way by codding . Option 1 I will tell you some commands and brief descriptions, Go to the help file for detailed description. findkey() , applylocate() These are used to find a particular record in the rowset. findkey() uses an index to find the row applylocate() doesnot require an index. Once you have located the particular record use beginedit() to change the required values and save() to save the changes. Option 2 Use xdml commands use table goto / seek replace All these commands work the same way as in old dbase. Option 3 Use a sql command update table set field1 = field1+Qty where keyfield = "key field" > 4.And also the concern amount in related party_account or other account(various amount,and account like SGST amount,CGST amount or IGST Amount(various taxes),discount,intrest,charges, net to pay etc) .  .. the same style of code or you can give example) > 5.My thinking codding at the time of custom component toolbar (in Save) the codding should be there or in form creating with data-module . > 6.I am stuck here. > 7.And codding I am stuck. Have you gone through Ken's Tutorial. Please read and develop that code. You will learn how to set up entry fields. If you just read through the lines you will forget how things are done. Data modules just open all your tables for you. For eg. the tables required in invoice form and print invoice are the same. So using a datamodule makes sense. The same datamodule is reused in the report. I will recommend starting from a small form with only 1 table involved so that you get a hang of how things work. When you go in for purchase entry or sales entry forms, they require multiple tables and hence a little bit more cumbersome. And if you are stuck in some coding send us the form and related tables with specific problem.You will get help Regards Akshat
