Idoc Error Message DELFOR message type

Hello Gurus,

I am trying to process an inbound idoc file with DELFOR message type.

I have the following ALE configuration :

Message type DELFOR

Process code DELI

Function module IDOC_INPUT_DELINS_START

When process the idoc file, I have the following error :

Function module not allowed: IDOC_INPUT_DELINS_START

Message No. B1252

Diagnosis

The function module IDOC_INPUT_DELINS_START and the application object type BUS2035 which were determined are not valid for this IDoc.

I do not know which function module to use or which process code to use.

Thanks in advance.
