Developing BAPIs for Interactive Processing
Prerequisites
Inbound IDoc processing in ALE supports IDoc function modules that execute a CALL TRANSACTION. This enables an IDoc to be posted interactively whereby you work through the transaction screens displayed.
This is not possible with BAPI-ALE interfaces generated from standard BAPIs because the BAPIs do not have a dialog interface. If you require an BAPI-ALE interface with a CALL TRANSACTION to a dialog transaction, you can develop your own BAPI that displays the transaction screens for ALE error handling.

Customer Enhancements in the BAPI Programming guide.Procedure
The ALE layer puts a parameter in the global memory that can be requested in the BAPI source code as follows:
Data: pi_input_method like bdwfap_par-inputmethod.
...
Import pi_input_method from memory id 'ALE_INPUT_METHOD'.
...
The parameter pi_input_method can have the following values:
Value |
Description |
" " (initial) |
Request without dialog screens |
"E" |
Only display screen if an error has occurred on it. |
"A" |
Display all screens |
