Hi,
I am converting a Lotus note program using rfc_call_transaction to vs.net progrma with sap connector v1.0.2 using vb.net. However I encountered the following message when I debug the program "Start screen does not exist in batch input data".
I would like to know is the following syntax the correct way to code an rfc_transaction call. The following is an extract of my coding:
Dim BDCtable As New SAPProxyDll1.BDCDATATable
Dim BDCdata As New SAPProxyDll1.BDCDATA
Dim msginf As New SAPProxyDll1.MESSAGEINF
Dim strProgram = "SAPMM06E"
BDCdata.Program = strProgram
BDCdata.Dynbegin = "X"
BDCdata.Dynpro = 105
BDCdata.Fnam = ""
BDCdata.Fval = ""
BDCtable.Add(BDCdata)
BDCdata.Program = ""
BDCdata.Dynbegin = ""
BDCdata.Dynpro = ""
BDCdata.Fnam = "BDC_OKCODE"
BDCdata.Fval = "/00"
BDCtable.Add(BDCdata).....
....
SAPProxy.Rfc_Call_Transaction("ME22", "BS", msginf, BDCtable)
What is the correct way to set up the BDC table? Or is there any sample coding for ref_call_transaction ?
Thanks and Regards
First, the previous response is correct, the DYNPRO field is a string field. Second, what is the "BS" value in the UPDMODE field? That is supposed to be a 1-character field, and I usually leave it blank. But it seems you are mostly on the right track with your coding.
Good luck with your BDC. I use it for a number of things, but it's better to use a BAPI rfc if you can. There are BAPIs for PO creation and releasing, but apparently not (in 4.6B) a PO change BAPI.
If you change to this code it should work to get you to the next screen (dynpro) number:
BDCdata.Program = strProgram
BDCdata.Dynbegin = "X"
BDCdata.Dynpro = "0105"
BDCdata.Fnam = ""
BDCdata.Fval = ""
BDCtable.Add(BDCdata)
BDCdata.Program = ""
BDCdata.Dynbegin = ""
BDCdata.Dynpro = "0105"
BDCdata.Fnam = "RM06E-BSTNR"
BDCdata.Fval = "(put PO number here)"
BDCtable.Add(BDCdata)
BDCdata.Program = ""
BDCdata.Dynbegin = ""
BDCdata.Dynpro = ""
BDCdata.Fnam = "BDC_OKCODE"
BDCdata.Fval = "/00"
BDCtable.Add(BDCdata).....
Then you would be on another screen (dynpro) so your next line would need to specify the next screen number (probably "0120" instead of "0105". Etc.

Hi there,
Just a quick bet ... judging on the "error message" you are getting ...
What is the type of "BDCdata.Dynpro" ? Your code suggest int but in SAP I would write "0105" in stead of 105 ...
Bye,
Steven
