Maintaining Infotype Characteristics 
When an infotype is created, the system does not automatically create the table entries that define the infotype characteristics (tables T582A and T582S). For this reason, you must create the appropriate entries in the tables yourself. View V_T582A enables you to maintain these tables.
If you want to maintain the characteristics of an infotype, proceed as follows:
You access the Create Infotype screen:
When you specify the infotype number, please remember to enter any leading zeros.
This accesses the Display View "Infotypes": Overview screen.
This accesses the Change View "Infotypes": Overview screen.
You can create new entries by
– choosing Edit
® New entries or– copying an infotype entry with similar characteristics.
If you want to copy an existing entry, select the entry you want to copy and choose Edit
® Copy as.Result: You have maintained the characteristics of your infotype.
