In ME51N, I have to make one column of item details table read-only.

[former_member209920]

Hi,

I have to make one column of the item details in ME52N, read only based on some conditions (for some specific plants). I tried  analysing BADI(s) and user exits and even implicit enhancements, but I didn't got any succeed.

I don't want to chnage the code directly using the access key.

Can anyone suggest any possible way out?

Hi Manu,

The simplest way to do it is use SHD0 and create a screen variant for the same. There select the required field as read-only.

Hi Richa and Manu

SHD0 probably won't fit the requirement that the column is read-only only in certain conditions.  Check into badi ME_PROCESS_PO_CUST and the method FIELDSELECTION_ITEM.  I think that will let you make the column read-only or not depending on the data of the PO.

Thanks but it won't work as:

1. We can not give check conditions.

2. We need to create new Z transaction which will not accpeted by user.

Hi Jim,

Can you provide some details, because when I try to debug after keeping breakpoint it at method FIELDSELECTION_ITEM, it does not stop here.

Whereas it stops at other method FIELDSELECTION_ITEM_REFKEYS, but it does not control the display properties of the table control of the item details of the purchase requisition.

Thanks

Please check following,  it may help you.

Create a implit enahcnement at the end of this function module MEREQBADI_FS_ITEM (just before ENDFUNCTION). Let us know if you need help on implicit enhancemnt.

1. declare data

    DATA:     lw_req_item TYPE mereq_item, 

                   w_fieldselection  TYPE mmpur_fs.

  CONSTANTS: c_007       TYPE mmpur_metafield  VALUE '007'.  " Account assignment cat

Note : check the type group MMMFD in SE11 for all the list ,

2 .   check Purchase req data

IF im_item IS NOT INITIAL.

   CLEAR lw_req_item.

***Get item data

   CALL METHOD im_item->get_data

     RECEIVING

       re_data = lw_req_item.

ENDIF.

* Here you can check the Purchase req data lw_req_item like plant etc

if your condition match.

3.    LOOP AT ch_fieldselection INTO  w_fieldselection
                                        WHERE metafield = c_007.
                    w_fieldselection-fieldstatus = '*' .  " Disable
* Similarly you can try code enable / required etc
                MODIFY ch_fieldselection FROM  w_fieldselection.
                CLEAR w_fieldselection.
              ENDLOOP.

Hope it helps.

Let us know, in case any further help.

Hi Manu,

I did a closer look and I see that the badi only allows control over customer fields at the item level.  In my case the method does get called; but if you have no customer fields on the item it is not called.

Sorry for the wrong answer...
