MM Screen Enhancement

Step1: Open T-code SPRO and follow below steps

Step2: Create the function group

 

 

 

 

 

Step3: Create the subscreen which to be enhanced.

 

Screen0001: subscreen to be enhanced in Basic data(MM)

Screen0002: subscreen to be enhanced in MRP1(MM)

 

 

 

 

 

 

 

 

 

 

 

Step4:

Now goto SPRO transaction and add screen sequence by following below steps.

 

Go to screen sequence and click on data screens

 

Click on basic data and click sub screens

 

Add the screen 0001 for basic data enhancement as shown and click save.

Proceed same steps for enhancing MRP screen (0002 subscreen).

 

 

 

Added sub screen in MM Basic data.

 

 

Added sub screen in MM MRP view.

 

 

Updating custom screen fields into database:

Step5: Get the old structure values from Sap memory by using the function modules MARA_GET_SUB and MARC_GET_SUB and MAKT_GET_SUB..

 CALL FUNCTION 'MARA_GET_SUB'
  IMPORTING
   WMARA         = <gfs_mara>
   *XMARA         =
   *YMARA         =
          .

 CALL FUNCTION 'MARC_GET_SUB'
  IMPORTING
   WMARC         = <gfs_marc>
   *XMARC         =
   *YMARC         =
          .

 CALL FUNCTION 'MAKT_GET_SUB'
  IMPORTING
   WMAKT         = <gfs_makt>
   *XMAKT         =
   *YMAKT         =
          .

Step3: when save button clicked write the logic in PAI module of custom screen to Update old structure with screen variable values to corresponding  structure of material master.

Step4: Update the new structures to sap material master new structure by using function modules MARA_SET_SUB(for updating mara table custom fields) MARC_SET_SUB (updating marc table fields) and MAKT_SET_SUB(updating makt table fields).

IF  sy-tcode = 'BU'.
        <gfs_mara>-zdtb_global = gv_global.
        <gfs_mara>-zdtb_gdate  = gv_gdate.
        <gfs_marc>-zdtb_local = gv_local.
        <gfs_marc>-zdtb_ldate  = gv_ldate.

        CALL FUNCTION 'MARA_SET_SUB'
          EXPORTING
            wmara = <gfs_mara>.
        CALL FUNCTION 'MARC_SET_SUB'
          EXPORTING
            wmarc = <gfs_marc>.

        CALL FUNCTION 'MAKT_SET_SUB'
          EXPORTING
            wmakt = <gfs_makt>.
      ENDIF.

And sap in standard program flow it will checks the old structure with the new structure wmara,wmarc and wmakt which will responsible in finding the change in the structures so if any change then it will update the standard table field values.

Testcase:

Click save (ctrl +s)after entering the values.

It will updates the corresponding material master table custom field.
