DataSource Material

Hi

i have a problem, i createss an view of tables MARC and MBEW and them create the extractor for this view, but it sends the following to me message <i>"Invalid extract structure te</i>mplate" <i>You tried to generate an extract structure with the template structure ZMATERIAL_ATTR. This operation failed, because the template structure quantity fields or currency fields, for example, field STPRS refer to a different table.</i><i>Use the template structure to create a view or DDIC structure that does not contain the inadmissable fields.</i>

But i need this field how can do it

Regards
