WorksEach call to Z_SENDMAIL2 is associated with an email handling category taken either from parameter P_HNCAT or, if this parameter is not included in the function call, from table ZEMCTRL (see below for details on this distinction). The handling category is referenced in control table ZEHCAT, which contains the following instructions for processing the Z_SENDMAIL2 call based on the assigned handling category:
...
Every new call to Z_SENDMAIL2 should pass an explicit email handling category as parameter P_HNCAT. Because many programs that call Z_SENDMAIL2 pre-date the intercepting and logging modifications, the P_HNCAT parameter is currently optional so that such programs do not require modification simply to add a handling category to the function call. It is intended, however, that every existing call to Z_SENDMAIL2 will eventually be modified to pass an explicit email handling category.
The table of current email handling category assignments can be found here.
The most direct way to associate a handling category with an existing call to Z_SENDMAIL2 is to modify the calling program to explicitly pass an email handling category as parameter P_HNCAT, and then transport the modified program to the R/3 test and other environments.
