BDC Issue

Hi

Considering that i am new to BDC, pls. ignore if i have made any mistakes

I have 3 querries :-

(1) Open_group and close_group FMs are not mandatory for CALL Tr. Then how can we create a new session for the call Tr. BDC. Because unless We create a new session, we cant post the data. If your answer is BDC_INSERT FM also opens a new session, then the same thing should apply to "Generate Session" BDC. That means open_group and close_group FMs should not be mandatory for "Generate Session" BDC. But that is not true.

(2) Suppose, we have recordings for 2 applications (A1 & A2). Then while creating BDC for "Generate Session", which path should we follow -

BDC_OPEN_GROUP

Map the data for Application A1

BDC_INSERT_GROUP

BDC_CLOSE_GROUP

BDC_OPEN_GROUP

Map the data for Application A2

BDC_INSERT_GROUP

BDC_CLOSE_GROUP

OR

BDC_OPEN_GROUP

Map the data for Application A1

BDC_INSERT_GROUP

Map the data for Application A2

BDC_INSERT_GROUP

BDC_CLOSE_GROUP

My question is simple - For N no. of applications we should open and close sessions N no. of times or shoud we do it only once.

(3) Are we creating a session in CALL Tr BDC. If yes, then what is the session name and in sm35 Will we be able to find it or there is any other transaction to see it. If No, then what is the use of "Keep Sessio & Lock Date" in the selection screen for CALL Tr.?

Regards,

Debi
