ALE Serialization :The concept of Serialization comes in when their requires ordering of the Message Types to avoid delays in transferring Idocs .Interdependent messages can be serially distributed through 3 different ways.Serialized messages can be of different types, all messages here relate to one special application object.Serialized can be both Master data and Transactional data. Transaction to maintain serialization group is BD44.
IDoc serialization is needed when we want the messages to flow in certain order.
Example: when we send vendor details (CREMAS), the receiver system might expect the address of vendor (ADRMAS) to be present in the system before vendor details(CREMAS) arrive .
In such cases, we need to setup in ALE, the serialization like ADRMAS should be sent before CREMAS.
Serialization technique will be helpful most of the time in idoc to flat file or external system updation. Due to some technical problems some times idoc sender side sequence will be change, so accordingly receiver side data sequence will be change, due to this problem we are using serialization technique. Most of the time this technique will be use in industrial requirement. For configuration find below link.
When IDoc serialization by IDoc adapter is required and also when ALE serialization of IDoc's is requried? - When IDOCs are sent from R/3 to XI, then IDOC serialization is done by IDOC adapter......When you are sending IDOCs from one R/3 system to another R/3 system directly using ALE communication, then you require ALE serialization of IDOCs..........So depending on your scenario, you will be using IDOC adapter or doing ALE serialization or using both.
and what about file > XI > IDOC scenario what kind of serialization is this?
I have a similar dilema where i need to post ADRMAS03 before CREMAS05 in R3 for the above scenario. But dont know how to set up serialization since wverywhere i have seen they only describe serialization from R3 to R3 or IDOC > XI > IDOC.....but never my scenario File > XI > IDOC.
