BAPI Mandatory Fields

[Former Member]

I am calling BAPIs through the Newtweaver JCO proxy classes . However how can I identify which attributes of the specific bapi are mandatory. The bapi explorer in SAP shows only the import parameters that are mandatory. how could I know which attributes in the ABAP Dictionary are mandatory....?

If you have imported the BAPI in XI, you can open it and check the occurances. When ever a node or a field is having the minimum occurance as 1 then it is a mandatory field.
