i need to create sales order from an external system using Idocs. we are using ORDERS05. We needs to save data in some custom fields. hence we have extended the idoc. But the Z* fields are not at the screen level. The function module 'IDOC_INPUT_ORDERS' uses call transaction and hence we are unable to save data in the Z fields.
Please advice some alternate approach.
We are looking into the possibility of using a custom function module and calling the create BAPI. Please advice is there is a better approach.
Thanks & Regards,
