I need to validate some item level data with the header data, So i wrote the code in User Exit. Its validating well, but if i press save button its simple asking a dialog and the PO is getting saved.
i have tried EXIT_SAPMM06E_007, EXIT_SAPMM06E_006 and EXIT_SAPMM06E_012 also. In call cases, its validating properly with throwing a message. But i am able to save...
can you please let me know your views on this.
