transaction handling in post event handler in AX7

Posted on by mail2vd 1,330

Hi,

I have an event handler written where i am throwing an error based on condition.

I just want to know whether it would revert the original action which has triggered this event handler? Do I really need to use ttsbegin...ttscommit block in this event handler. 

I want the original action to revert whatever it has done if this post event handler throws an exception anywhere in the code. Even I don't want to write try...catch  block.

I have written this event handler on the 'updated' event of the table.

    Yea, need to use ttsbegin & ttscommit;

    like below..

    ttsbegin;

    //// Business logic

    if (condition)

    throw error (" transactio reverted");

    ttscommit;

    I didn't get you.

    ttsbegin;

    //// Business logic - execution of the business logic

    //here business logic may have events or event handlers.

    ttscommit;

    i have written post event handler on update method of the table which gets executed after update happens on the table.

    So just want to know what happens to update method code that has already executed before the post event handler exception.

    Did you find a solution for this? I have a somewhat similar situation where I need to prevent the user from entering a new record from the table.initfromOtherTable() method (post event handler)

    initFrom* method is a wrong place for validation logic. What about using onValidatingWrite event?
