Hi,

I am trying to upload vendor master through IDOC.I am also sending bank data in my IDOC.But it gives the below error

Fill all required fields SAPLBANK 0100 BNKA-BANKA

We have created the bank and details exist for that bank.

We are giving Bank Country Key,BANKKEY and BANKACCOUNTNUMBER details in IDOC.

When I have Reprocessed the IDOC thru WE19 in Foreground mode It goes to bank screen twice.First time the okcode is 06 and second time the okcode is 16 which take the control to other screen where it ask bank name.But Bank name already exist for that bank.we are not giving bankname from the idoc.
