Current restrictions: You cannot display long texts. You cannot display sub-items. You cannot display classification data of BOM items for batches. You can only display one alternative or variant. You cannot enter an alternative for module CSAP_MAT_BOM_READ, so you always see alternative 01. The following example came from a posting on the SAP-R3-L mailing list.
Example: data: begin of tstk2 occurs 0. include structure stko_api02. data: end of tstk2. data: begin of tstp2 occurs 0. include structure stpo_api02. data: end of tstp2. data: begin of tdep_data occurs 0. include structure csdep_data. data: end of tdep_data. data: begin of tdep_descr occurs 0. include structure csdep_descr. data: end of tdep_descr. data: begin of tdep_source occurs 0. include structure csdep_source. data: end of tdep_source. data: begin of tdep_order occurs 0. include structure csdep_order. data: end of tdep_order. data: begin of tdep_doc occurs 0. include structure csdep_doc. data: end of tdep_doc. data: flg_warning like capiflag-flwarning. call function 'CSAP_MAT_BOM_READ' exporting material = 'MAT100' plant = '0001' bom_usage = '1' valid_from = '20.12.1996' * valid_to importing fl_warning = flg_warning tables t_stko = tstk2 t_stpo = tstp2 t_dep_data = tdep_data t_dep_descr = tdep_descr t_dep_source = tdep_source t_dep_order = tdep_order t_dep_doc = tdep_doc exceptions error = 1.

This function module pops up a screen that is just like all the other F4 helps, so it looks like the rest of the SAP system.
