Select problem during excuting SM35

Question

Hi, all:
  i use BDC to extent material between plants by MM01.
  You know, there are some fields that will be gray if it has been filled in one plant,such as MARA-SPART,MARA-MTVFP.
  So when i use BDC i have to check if this field has value in table mara as one material.
  the code like this:
sales/plant
  perform bdc_dynpro      using 'SAPLMGMM' '5000'.
  perform bdc_field       using 'BDC_OKCODE'
                                '=BU'.
  clear tempc1.
  select single MTVFP from marc into tempc1 where matnr = SEQ_FILEH-matnr
                                              and werks = SEQ_FILEH-werks.
  if sy-subrc = 0 and not tempc1 is initial.
  else.
    perform bdc_field       using 'MARC-MTVFP'
                                  SEQ_FILEH-MTVFP.
  endif.
  above code runs well by call transaction. But when i use it in SM35, all materials can not be extended, because it gives the 'MARC-MTVFP' is not input field.
  this maybe the DB(mara) does not updated in-phase,
  any advice?

Hi,
I have encountered similar issues while updating some data in sales orders..Now call transaction works becoz the messages r suppressed.But iam doubtful about this as well if the values r being updated in MARA or not. Please check the bdcmsgcol table if ur getting the message which says "field not avaialable for input".
In general for this error maybe u can try to put validations for the cases when this field will be greyed out.U can skip that screen or not populate that field for this case.
I hope it helps.
