i've searched quite a bit for user-exits and what they are and still can't fully grasp the concept. can someone explain them and their use in generic terms, please. also, what does this mean and how do i access it:
can you please check MV45AFZZ - FORM USEREXIT_FIELD_MODIFICATION ?
Astromar,
Lets talk with an example:- Say you want your sales order quantity should not be modified once it has been saved even though you have VA02 authorization.... The options for you are 1) use screen variants 2) write code in sales order program
SAP has provided us some of the places in terms of user exits where we can write the codes.
When some one says user Exit in MV45 AFZZ , MV45AFzz is the name of the program which contains different user exit like FORM USEREXIT_FIELD_MODIFICATION these all are forms. Under these forms we write codes. you can check MV45AFzz in SE38.
Thanks,
Raja

Hi,
In general,SAP provides all the standard operations.
If you want to go for some enhancements or exception we have to go for user exits.
One of such an example is the order quantity field should be greyed out in VA02 T.Code.
And one more example is to make the field item category "Editable".
First we have to idetify which user exit is used for which operation.
First we have to goto the T.Code "CMOD".
Here the user exit will be defined in "Projects".
After this we have to link this one to our program.In our case it is "MV45AFZZ".
All this thing will be done by ABAPer.
Once they have included that exit,we have to check for this functionality.
Regards,
Krishna.
