Hi,
Better to use FOR ALL ENTRIES, dont use inner join.
refer below code
*&      Form  sub_read_mara                                            *
This form will Select the material number material type material    *
group & batch management indicator from table mara using given      *
material number                                                     *
FORM sub_read_mara .
*--Select query to pick the material number material group material type
and batch management from table MARA
  SELECT matnr                            "Material Number
         mtart                            "Material Type
         matkl                            "Material Group
         xchpf                            "Batch Management
         FROM mara                        "Material Master
         INTO TABLE i_mara
         WHERE matnr IN s_matnr
         AND   mtart IN s_mtart
         AND   matkl IN s_matkl .
*--Check Subrc
  IF sy-subrc <> 0.
*--No data found for the given selection criteria.
    MESSAGE i001.
    LEAVE TO LIST-PROCESSING.
  ELSE.
*--Sort table by Material Number
    SORT i_mara BY matnr.
  ENDIF.
ENDFORM.                                  "sub_read_mara
*&      Form  sub_read_marc                                            *
This form will Select the material number plant purchasing group &  *
MRP controller from table MARC using given material number plant &  *
purchasing group.                                                   *
FORM sub_read_marc .
  IF NOT i_mara[] IS INITIAL.
*--Select query to pick the material number plant purchasing group &
MRP controller from table MARC
    SELECT matnr                            "Material Number
           werks                            "Plant
           ekgrp                            "Purchasing Group
           dispo                            "MRP Controller
           FROM marc                        "Material Master
           INTO TABLE i_marc
           FOR ALL ENTRIES IN i_mara
           WHERE matnr = i_mara-matnr
           AND werks IN s_werks
           AND ekgrp IN s_ekgrp
           AND dispo IN s_dispo.
*--Check Subrc
    IF sy-subrc <> 0.
      MESSAGE i001.
      LEAVE TO LIST-PROCESSING.
    ELSE.
*--Sort table by Material Number Plant
      SORT i_marc BY matnr werks.
    ENDIF.
  ENDIF.
ENDFORM.                                  "sub_read_marc
