Transferring iDocs between A2A SAP systems?
What are the advantages of transferring iDocs between A2A through SAP XI?
Basically when u want to transfer IDOCs in A2A scenarios it can be done by using ALE settings .But XI comes in to picture when u transfer data based on certain conditions like
based on occurence of a particular field F1 from source side
some segment at SEG3 at target side should be repeated....
Like this there will be different cases so in order to acheive this
XI will be used instead of going to transfer by ALE.
