Multimapping problem

Hi,

I have a new scenario of File -> Idoc

                                           -> File

Here Source file (# separated) will be like that -

1#a1#a2#a3#a4

1#a1#a2#a3#a4

1#a1#a2#a3#a4

9#3

For this I have done a multi-mapping -

But when the source file is picked up through communication channel its creating an additional tag <Recordset> , that's why giving an mapping error -

Please give any suggestion to remove this extra tag
