You could analyze FM ME_FILL_KOMK_PO and ME_FILL_KOMP_PO to get a clear (or not) idea of the involved table (EKKO, EKPO, EINA, KONV, KONP, etc.)
*Header CALL FUNCTION 'ME_FILL_KOMK_PO' EXPORTING i_ekko = ekko i_ekpo = ekpo i_lfa1 = lfa1 i_lfm1 = lfm1 i_t001w = t001w i_t001 = t001 i_kalsm = kalsm i_kappl = 'M' i_egimp = egimp i_trtyp = trtyp i_kvorg = lc_kvorg IMPORTING e_komk = komk. *Items CALL FUNCTION 'ME_FILL_KOMP_PO' EXPORTING i_ekpo = ekpo i_t001w = t001w i_ekko = ekko i_komk = komk i_mt06e = mt06e " Look at include LMATLCAS or use MATERIAL_READ
i_eina = *eina i_eine = *eine i_uebpo = uebpo IMPORTING e_komp = komp TABLES t_knt = knt.
