BW Generic data source problem

Hi all,

I create a view and after this i run t-code rso2 for making that view as data source but when i save that data source it shows one status error

<b>invalid extract structure template zmm_slo(data base view name) of data source

zmm_slo_01</b>

when i click on that error it shows

<b>You tried to generate an extract structure with the template structure ZMM_SLO_MOV. This operation failed, because the template structure quantity fields or currency fields, for example, field SALK3 refer to a different table.</b>

this diagnosis

can anybody tell me how can i resolve this error and make my vies as data source

Thanks
