Customized entries for ACTVT field

Question

Dear Gurus,
I have created customized Authorization object with the help of post on forum but I am unable to figure out to create customized entries for ACTVT. 
Eg: Instead of activity 01, 02, 03 ....ect I want to create Z1, Z2 & Z3.
How can I create this entries ? what are the steps involved and how to I assign it to my customized Auth object ?
Thanks in advance,
Soyunee

Answer 1

The original requirement from functional consultant is to create a customised Authorization with 2 fields 1. Company code 2. Activity.
And the second requirement is to add activity entries Z1 - Extract invoice & Z2 - Approve invoice.
Since you mentioned you are creating a custom authorization object, I believe the auth check would be made by a customized program or a BADI too.
If my assumption is correct, you don't need to create custom field values for SAP standard field ACTVT, rather you can have the custom program logic designed in such a way that it triggers desired action while checking the already existing SAP delivered field values for ACTVT.
For  instance:
Logic is designed so that a value ACTVT= 01 would trigger action Extract Invoice and ACTVT= 02 would trigger action Approve Invoice
To summarize, you can use any standard field values for ACTVT and have desired action defined for that value in your program logic. I have come across such scenerios in the past and quite sure this concept works!
Try it out:)
P.S: While creating the custom object, it would be a good idea to document the relevant action that your custom program will trigger for each of the standard values for field ACTVT ( which you are going to use) in the object documentation section of tcode SU21 for future reference.
