We have 4 choices in LSMW
1. Batch/Direct Impot method
2. Batch Input Recording Method
3. Business Object Method (BAPI)
4. Idoc (Intermediate Docs)
I have done tutorials in first and 1 and 2. I need tutorials for 3 and 4.During Idoc,when I try to create LSMW port,it says it doesnt find LSMW.
My understanding:
In SAP ,Data transfer can be done in two ways.
1. LSMW - contains 4 ways as said above
2. BDC
i)call transaction
ii)session method
Is my understanding true?How ALE is linked to above?
Please give links for tutorials for whatever possible methods.
Thanks
