Hallo,
I want to share what happend to me with my bdc Program.
I was able to create Sessions of Batch input (SM35)  through the Creation Program ZRSFFL0A (writen below) from 29.04.2008 to 21.05.2008. On May 21 I changed a parameter to play an error, since than the proper original programme has never worked.
Now while I am executing(F8) it shows the message in one dialog box 'BDC_OPEN_GROUP user name is invalid'. I don't know why.
**During Debugging the program stopped Function SAPLLANG:
FUNCTION CONVERSION_EXIT_ISOLA_OUTPUT.
""Lokale Schnittstelle:
*"       IMPORTING
*"             VALUE(INPUT)
*"       EXPORTING
*"             VALUE(OUTPUT)
  OUTPUT = SAVE_INPUT(1) = INPUT.
  CHECK SAVE_INPUT(1) NA ' *'.
  SELECT SINGLE * FROM T002 WHERE SPRAS = INPUT.
  CHECK SY-SUBRC = 0.
  OUTPUT = T002-LAISO.
ENDFUNCTION.
