Dear Rajarshi,

BDC (Batch Data Communication) - is one of the methods for uploading the data. You have two options with BDC, namely Session and Call Transaction.

First you would record a particular transaction with SHDB simulating sample transaction entry. Then you would use this recording to create a 'Z' program.

With session method a session will be generated that needs to be processed in Transacton SM35 with Foreground, Background, or Errors only mode. You can view and analyze session log after processing the session.

With call transaction you would specify the mode in the program itself. Hence, no session is generated in SM35 in this case.

please visit the following link for more information:

Z programs are custom programs. They could be reports, transactions, scripts, smartforms, BDCs, BAPIs etc. You would develop them if there is no SAP standard program available that meets your requirement.

Reward points if this is helpful.

Hi Rajarshi,

These links will be useful to you!

About a Z program, as the name suggests, its a user created program. There are 2 types of Z programs,, one of which is the copy paste of standard SAP programs and some customizing done on them. The second type of Z program is the user developed one, fully developed by the ABAPer.

Hope this helps,

Thanks,
