Material master data enhancement (2)

I wrote a document about material master data enhancement ABAP essays - The material master interface is enhanced , Need configuration + Strengthen the code , Today, I will upgrade the function , Enhance the material master data tab

1. Enhance the material master data table

append custom field in MARA

Add whatever field you want

2. Material master data configuration

1. To configure 1 Path is :SPRO-> logistics - routine -> Material master data -> Configure the material master record -> Create a custom sub screen program

Create the corresponding function group

For the screen 0001 Add a field , increase PAI PBO The logic of module

among status_0001,set_ztab_mara_01 The code is

MODULE status_0001 OUTPUT.
  IF sy-tcode = 'MM02'
  OR sy-tcode = 'MM03'.
    CALL FUNCTION 'MARA_GET_SUB'
      IMPORTING
        wmara = mara
        xmara = *mara
        ymara = lmara.
  ENDIF.
  IF sy-tcode = 'MM03'.
    LOOP AT SCREEN.
      screen-input = '0'.
      MODIFY SCREEN.
    ENDLOOP.
  ENDIF.
ENDMODULE.
MODULE set_ztab_mara_01 INPUT.
  DATA:ls_cust TYPE ztab_mara_01 .
  MOVE-CORRESPONDING mara TO ls_cust .
  CALL FUNCTION 'MARA_GET_SUB'
    IMPORTING
      wmara = mara
      xmara = *mara
      ymara = lmara.
  MOVE-CORRESPONDING ls_cust TO mara .
  CALL FUNCTION 'MARA_SET_SUB'
    EXPORTING
      wmara = mara.
ENDMODULE.

Copy

among function MARA_GET_SUB and MARA_SET_SUB Get and update respectively MM02/MM01/MM03 Memory variable MARA Value

1. To configure 2 Then we continue to choose spro-> logistics - routine -> Material master data -> Configure the material master record -> Define the structure of the data screen for each screen sequence

The configuration we are currently using is 21 Screen order

In the data screen interface, we add a new piece of data

At the same time, we configure the data sub screen , Fill in the... We just created FUNCTION GROUOP Inside the screen among SAPLMGD1->1002 It is the header that displays the material number

You can click on... On the right View data screen View the generated screen

1. To configure 3 Save after exit , We enter spro-> logistics - routine -> Material master data -> Configure the material master record -> Select... In the maintenance order of the main screen and the additional screen 21 Double click enter on the serial number screen We can see the configured sub screen , If you want to Z1 The screen moves up , Then change the sequence number

Now let's go into MM03 Enter materials in the interface and click enter to view the new view for selection

In fact, we can now modify and save the new fields

3. Data update

We were in The material master interface is enhanced I've already talked about it in , How to perform enhanced verification on material master data ,

Here we simply do a uniqueness check : Enable EXIT_SAPLMGMU_001 exit and CI_MMH1

*&---------------------------------------------------------------------*
*&  contain                ZXMG0U02
*&---------------------------------------------------------------------*
IF sy-ucomm = 'BU' OR sy-ucomm = 'YES'.
  IF sy-tcode = 'MM01' OR sy-tcode = 'MM02'.
    CHECK wmara-custom_field1 IS NOT INITIAL.
    SELECT matnr INTO TABLE @DATA(lt_matnr)
      FROM mara WHERE custom_field1 = @wmara-custom_field1.
    IF sy-subrc EQ 0.
      DELETE lt_matnr WHERE matnr = wmara-matnr.
      IF lt_matnr[] IS NOT INITIAL.
        READ TABLE lt_matnr INDEX 1 INTO DATA(ls_matnr).
        MESSAGE e001(ztab) WITH wmara-custom_field1 ls_matnr-matnr.
      ENDIF.
    ENDIF.
  ENDIF.
ENDIF.

Copy

When we double-click CI_MMH1 when , It is found that the structure does not exist , We directly SE11 establish , Then write in the enhanced fields

Actually CI_MMH1 This is not possible in our enhancements , But this creates CI_MMH1 Is in the structure BMMH1 Medium , be used for LSMW- If there is no enhancement here ,LSMW Enhanced field batch import cannot be performed

After activation and saving , We are looking for another material SGPI002, Enter... In the customer field 1234567890 preservation , This will prompt :

4. Be careful

In the top code sy-tcode = 'MM01' Yes MM01 The uniqueness verification is also performed because ,MM01 You can extend the existing materials
