I have list of document, i need to change the childtable values in more than one document at a time but i got error like
Error: Document has been modified after you have opened it

2

Is there any client script apply it then remove it and check it. otherwise refactor it.

3

can you please give the code for remove that, or any other way for this
actually all actions are done, but i got only error dialog

There is no code for it. If you have added any code, you need to update it. In which doctype are you having that issue?

i use the try catch in frontend like

try{
    //call to the backend function to update ...
    // after the all word done it comes here 
    // backend throw error so it will go catch after all works done
}
catch(error){
  if (error.exception === "frappe.exceptions.TimestampMismatchError"){
    //throw error msg with our words
}
}

this is the one of the solution, but not correct way that why i am moving to edit the data using

frappe.db.set_value()

this one is working fine without throwing error
reference → Database API

i edit the child table of the document with frappe.db.set_value() if you want more about code pm
