Calling table insert and update methods conditionally.

In AX, there can be situations where you have to write code for table insert and update. Lets say you are exposing some AX logic by AIF or manipulating data with temp. tables.  In these situations, you may develop only one method both for Insert and update. All the table fields data can be passed to this method by parameters. The important question is when to conditionally execute the Insert and Update method. The answer is the RecID field. RecId is always greater than zero for any record that is being selected from the database. So for that condition you can call the update method. Similarly, if the table buffer is populated with all the fields except the RecID field, then it means that  you have just filled all those fields and Insert methods needs to be called for that condition. To implement this logic all you have to do is to write the update and insert method in a If condition like:

If(Table1.Recid  > 0 )

{

Table1.update();

}

Else

{

Table1.insert();

}
