Problem in BDC program

Former Member — Thu, 17 Dec 2009 07:21:36 GMT

Dear Guru's,

I have written a BDC for uploading billing from delivery , and creating header text in the same.

It contains 3 perform statement in start-of-selection.

START-OF-SELECTION.

PERFORM data_upload_itab. " Where I upload data into internal table.

PERFORM bdc_data1. " Where recording done by call transaction.

PERFORM CREATE_HEADER_TEXT. "Where text is created via FM CREATE_TEXT.

but a strange is that this above coding is not executed properly , as after perform BDC_DATA1 the next perform statement not

get executed.

but if I put a break point in between BDC_DATA1 and CREATE_HEADER_TEXT then it is working fine. I am using MESSTAB(BDC's)

to get the document number which is created in BDC_DATA1 and then use it for create_text.

I think you are missing commit_text or save_text function calls..in your code..

Execution is not going to perform CREATE_HEADER_TEXT.

It skip the perform segment.

I have tried ur suggession , but still it is not working.

By the way the info was helpful

Thanks.

When you are debugging a program, you are delaying its execution a while, although you press F8 when the breakpoint stops the program and creates the debugging session.

When you execute the program "normally", this delay doesn't exist.

Can you check something? Add a small delay between both performs and tell us the result. Start with 5s (for example), and if it works, lower the amount of seconds until it stops working.

A better and cleaner option is to add a check before the second PERFORM to be sure your item has been created before continue, and not a crude WAIT (but you can save some time testing my supposition using WAIT, and if I'm right, then you can code a cleaner and better check).

Vicenc,

Your suggession is correct. when I put WAIT UP TO 1 SECONDS then it is executed properly. So , That means it is basically using the COMMIT time for the documents in the database , and due to this time the CREATE_TEXT is not working as it does not have any document at that moment of execution.

Yeah this is really helpful answer , but still looking for alternate of WAIT statement.

Thanks,

Sanku.

The alternate for a WAIT statement is a DO-ENDDO. Something like:

do.
  select single.
  if sy-subrc = 0.
    exit loop.
  elseif time_excessive.
    message error_not_created.
  endif.
enddo.

Just ensure yourself the DO-ENDDO will not last too much. I cannot provide you the tables where you must do the SELECT because I don't know which ones are updated with your BDC. But I'm sure you've got the idea
