Hi,
Thanks very much for your attention.
I just doubt considerably my understand about BAdI when I encountered the problems.The questions are as follows:
As you know,a classic BAdI exists in the system with the name "BADI_MATERIAL_REF",
So I create a an implementaion naming "Z_IMP_MATERIAL_REF",and realizing the BAdI Definition's interface in the class that generated automaticaly.After all above,I started related transaction and found
the enhancement did not work.
-->So I am confused. How dose the standard program invoke our defined BAdI Implementation or Class?
What other work should I do if I want the BAdI implemetation effective?
Thank you again and again!
