is it allowed to add my_message to T100?

Hi Experts,

In one of my interface EDI IDOC prog., am paasing my_message to idoc, its message class is ZZ and # is 000.

In ZZ class, this # value is always & &.

so, am using this all in my Z prog. and working fine.

but, here in this case, am getting dump.

so, i wanna go with SAP T100 ,

so, let me know that,

1- is it allowed to add my_message to T100?

2- if so, wht is the application area?

3- wht is the VIEW to add new entry of my_message to T100?

thanq
