SAP mutiple use BADI and enhancement spot implementation (Business Add-In)
A BADI that has the multiple use checkbox ticked simply means that you can not only create multiple instances but also have more than 1 of them active at the same time.
This is unlike a standard BADI without the multiple use option ticked, which can only have one implementation active at any one time.
There is however one caveat to multiple use badi�s, although you can have multiple implementations you can�t specify which order these will be fired in.
Therefore, each implementation needs to be coded as a separate entity and must not rely on a specific execution sequence or another one being completed first
i.e. you could not have one performing some checks and another updating a database based on these checks.
To be honest I can�t think of an instance where this would cause you too much of a problem. Why would you need to split connected coding across two
implementations? If you have come across a requirement to do this, please add it to the comments section below as there could be ways around this limitation if required!
There may be instances if you have a multi-national company, but filter values might help with this. I will cover this in more
detail at the end of this article.
One final point about Multiple use BADI�s, is that they can only have IMPORTING and CHANGING parameters.
Implementing a multiple use BADI
Well Implementing a multiple use badi is much the same as implementing a none-multiuse BADI so see that article for full step by step details...You basically execute Business Add-In(BADI) transaction SE18, choose the BAdI option, enter a multiple use BADI name ( i.e. ADDRESS_UPDATE ) and press display. Also if you want to know which badi is executed within a particular transaction see here for how to find where a BADI is triggered
Note this BADI has the multiple use badi checkbox ticked
Now follow the usual classic BADI implementation steps i.e. select menu option Implementation->Create
and give the implementation a name such as Z_ADDRESS_UPDATE.
On the next screen enter some implementation short text and press save
Etc etc...until you you have added your desired ABAP code into BADI methods ( within the interface tab) and then activated the implementation.
Activate multiple BADI implementations
As this is a multiple use BADI you can now create a second, third, four etc implementation and activate them without any problem. But remember they will not be executed in any particular sequence and it could be a different sequence each time.
BADI with filter-depend type value
There is an alternative way to allow you to create multiple active implementations of a BADI via the use of the filter-depend option to add a filter type value. This means that you can execute a different implementation depending on the value of the filter. see here for more details about BADI's with filter
