About bdc recording

Question

Hi Experts,
                    i am working with " ZTOOLREV ' transaction code. i filled all the mandatory fields. which is required. i have done the recording.  i maintain one function module in se37. and converted this fm to web service.  that i have to send to my client
he will send the data through same web service.              here i maintain internal table mess_tab. here
i used EXPORT mess_tab TO MEMORY ID 'TOLLDATA'.
so i will use IMPORT mess_tab TO MEMORY ID 'TOLLDATA'.  i think data is in internal table.     so what to do after. how the data comes in ztoolrev after recording. using bdc call transaction.
i mean to say that the mandatory fields given by my client. how it is going to come in recording time. after that i am using save_text fm to save data.
Please guide me.

Answer 1

My 'expert opinion? What are you doing?
You created a BDC recording, fm (for web service), IMPORT TO MEMORY ID, EXPORT TO MEMORY ID, SAVE_TEXT....Why?
1. Are you providing a web service or consuming one? I guess both according to you post:
he will send the data through same web service
Same webservice?
2. What does this mean? Where and why did you use this and why would you want to use both?
i used EXPORT mess_tab TO MEMORY ID 'TOLLDATA'. so i will use IMPORT mess_tab TO MEMORY ID 'TOLLDATA'.
3.
i think data is in internal table.
. You think? If you don't even know, why would any 'outsider' do?
4. Where does the bdc fit into this 'picture'?
5. FM SAVE_TEXT......, again why, what is it for?
For you the expect any kind of answer, first make clear what it is you are trying to do here. Next ask a specific question. According to your posts you have been working on this ZTOOLREV transaction for quite some time now. So I guess, the requirement should be more than clear to you, correct? Explain it to us.
The way I see it now, it should be something like this:
1. You created a BDC recording for your ZTOOLREV transaction.
2. This BDC recording is called from within the webservice which is being called from an external application from your client (or is this 'client' the client you are now working for?).
3. One of the parameters is an internal table called MESS_TAB.  My guess is that this is the internal table used in CALL TRANSACTION for storing all messages in BDC recording. But where is the data for starting your BDC recording?
4. Data from the calling application (mess_tab) is used to fill the BDC recording.
5. At end of BDC recording you are doing a CALL TRANSACTION and return messages (MESS_TAB).
Leaves us with some unanswered questions like EXPORT and IMPORT TO MEMORY ID and FM SAVE_TEXT.
