Calling BAdIs 

Use

After their definition and independent of an implementation, BAdIs can be called using a combination of the ABAP statements GET BADI and CALL BADI:

·        GET BADI FILTERS f1=x1 ... fn=xn – selects the BAdI implementations whose filter condition is met by the filter values specified in the statement. The BAdI implementation classes assigned to the selected implementations are instantiated and passed to a simultaneously created BAdI object which serves as a handle for the implementation.

·        CALL BADI badi->meth – addresses the BAdI object which passes the call of BAdI methods to the object plug-ins known to the BAdI handle.

For detailed information about these statements, see the ABAP Keyword Documentation.

In the context of the Enhancement Framework, the above statements together form the enhancement spot element calls of an explicit enhancement option. Conceptually, they are part of the definition of an enhancement option.

Procedure

For a multiple-use BAdI, several implementations can be called one after the other using CALL BADI. The sequence in which several object plug-ins are called consecutively is the same in repeated calls, but it can be determined in advance in the BADI_SORTER enhancement spot using the predefined BAdI BADI_SORTER:

...

       1.      Create the new implementation BADI_SORTER.

       2.      Enter the name of the BAdI whose object plug-ins you want to call in a sorted sequence as the filter condition for the BADI_NAME filter.

       3.      Create a screen enhancement to query any kind of sort criterion.

The Enhancement Builder then displays this subscreen with each implementation of the BAdI to be sorted.

       4.      Implement the methods of the BAdI interface IF_BADI_SORTER according to your sort criteria in the BAdI implementation class.

Without this procedure, the sequence is undefined.
