This is a self help Blog showcasing how to achieve sequence order for classic BADI Implementation’s. The Sequence of implementations can be achieved using 2 approach in case of classic BADI’s.  The second approach has some restriction


Approach 1 via Sort Technique


Ok here I have a Classic BADI ZDEMO_CLASSIC_BADI and an corresponding Interface ZIF_EX_DEMO_CLASSIC_BADI

There are 3 Implementations for the BADI. Lets try giving a implementation sequence via Sort.

To Sort, click Utilities -> Sort

If asked provide an Transport Request. That’s all !



Ok now the sorting criteria is available for multiple Implementations. Check as shown below.

Implement the sorting order. Enter a sorting value in the implementation, save and activate.

Ok lets do a quick test to verify the implementation sorting order.

After report execution, we see the implementation order sequence

Approach 2 via Filter values


The sorting can be achieved also via using Filter Type.


2 Options :

1) For a custom BADI, no issues.


2) For standard BADI, check if the filter values are enhanceable. If yes, you can add a new value to the value table of the Filter Type Data Element/Domain by calling the respective implementation. For more info, press F1 on the field enhanceable.

Create a filter for the BADI ZBADI_WITH_FILTER.


I have created a Data Element ZORDER_SEQUENCE (CHAR10) and used in in the Filter Type

Save the BADI.



Ok lets move to the Implementation part. We have 3 implementations.

Time for a quick test.

So we can use the two approach’s with a careful considerations for the BADI implementations order sequence. Hope this was helpful.
