Kaizen #118 - Mass Delete Records Across Modules (Part II)
Hey there! Welcome back to yet another insightful post in our Kaizen series!
Picking up the thread from our last post, let's explore how to automate the process of mass deleting child records directly from the parent record's details page. This approach eliminates the need to click the Cascade Delete button repeatedly, when dealing with parent records containing over 2000 child records.
Prevent Additional Clicks to Delete 2000+ Records
Step 1 - Get the Child Record Count
Make a COQL API call in the function and get the total number of child records associated with the specific parent record.
queryMap = Map(); queryMap.put("select_query","select COUNT(id) from Participants where Training_Program=" + id); response = invokeurl [ type :POST parameters:queryMap.toString() connection:"crm_oauth_connection" ]; |
Step 2 - Loops and Deluge Script
The count of child records obtained from the preceding step's response will determine the necessary iterations for executing the action.
---> To ascertain the number of iterations, divide the total record count by 2000, and consider the nearest largest integer as the iteration count.
---> Subsequently, the entire function from the earlier post will undergo looping. Whenever the button is clicked, the placeholders (whitespaces) will be filled in accordance with the record count division, ensuring seamless delete process.
---> If there are no child records available, then it should skip the loop and delete the parent record alone.
iterations = (response.getJSON("data").get(0).get("COUNT(id)") / 2000).ceil(); no_records_flag = false; if(iterations == 0) { no_records_flag = true; iterations = 1; } iterationString = "".leftPad(iterations).replaceAll(" ",",").toList().subList(0,iterations); for each iteration in iterationString { if(!no_records_flag) Handle the function code from previous post here. } |
Let us now check this from the details page of a Training Program with 7000 participants.
Looping Constraints in Functions
The maximum file size for the function code is 2 mb and less than 1 mb is preferable for the seamless execution, which translates to approximately 6,500 lines of code. Furthermore, the function's maximum execution time is capped at 5 minutes. Any function surpassing this limit will be automatically terminated, accompanied by the error message: The limit of time has reached its maximum 300000 (milliseconds).
