Urgent : Problem in changing BOM items using FM - CSAP_MAT_BOM_MAINTAIN

[Former Member]

Hi Experts ,

I am trying to change the quantity of the component in an existing BOM using the function module CSAP_MAT_BOM_MAINTAIN . But instead of changing the quantity of the component in the existing item , it is adding a new item with the changed quantity .

How to overcome this problem ..please help ...

Thanks.

Try using the FM CSAP_BOM_ITEM_MAINTAIN.

In the standard system, you need to use the following function modules to change a material BOM:

a. CSAP_MAT_BOM_OPEN

b. CSAP_BOM_ITEM_MAINTAIN

c. CSAP_MAT_BOM_CLOSE

For more information, check the below link.

Try the below code. It worked for me.

data: tstk1 type stko_api01.

*---- BOM header data structure
data: begin of tstk2.
          include structure stko_api02.
data: end of tstk2.
*---- BOM items table
data: begin of tstp3 occurs 0.
          include structure stpo_api03.
data: end of tstp3.

*---- Object dependencies table
*     Basis data
data: begin of tdep2_data occurs 0.
         include structure dep_data.
data: end of tdep2_data.
*     Description
data: begin of tdep2_descr occurs 0.
         include structure dep_descr.
data: end of tdep2_descr.
*     Source
data: begin of tdep2_source occurs 0.
         include structure dep_source.
data: end of tdep2_source.
*     Sequence
data: begin of tdep2_order occurs 0.
         include structure dep_order.
data: end of tdep2_order.
*     Documentation
data: begin of tdep2_doc occurs 0.
         include structure dep_doc.
data: end of tdep2_doc.

data: flg_warning like capiflag-flwarning.

Hi Balaji ,

Thanks for your reply .

Can u tell me where to see the Log of error message if the function module is not executed successfully .

In the Export Tab the parameter FL_WARNING gives the indication of error message . But actually where this error is logged , i am not able to find it out .

Please help .

Thanks ,

*- Initialize database log
   call function 'CALO_INIT_API'
        exceptions
             log_object_not_found     = 1
             log_sub_object_not_found = 2
             other_error              = 3
             others                   = 4.

The above piece of code initializes the DB log.

*- Change BOM
   call function 'CSAP_MAT_BOM_MAINTAIN'
        exporting
             material   = 'MAT100'
             plant      = '0001'
             bom_usage  = '1'
             valid_from = '14.10.1996'
             fl_bom_create = ' '
             fl_new_item = ' '
             i_stko  = tstko
        importing
             fl_warning = flg_warning
             o_stko     = tstk2
        tables
             t_stpo       = tstp3
        exceptions
             others  = 1.
   if sy-subrc eq 1.
*---- Error
*     Please see log
   endif.
   if flg_warning eq 'X'.
*---- Please see log for information, warning messages, and success
*     messages.
   Endif.

So in case of error, see log for information, warning messages, and success messages.

Hope this helps.

Thanks,

Hi,

You may have to check with your Basis guys. But if you want to get the actual message yourself, comment out the below code.

*- Initialize database log
   call function 'CALO_INIT_API'
        exceptions
             log_object_not_found     = 1
             log_sub_object_not_found = 2
             other_error              = 3
             others                 

use the below code to see the message yourself on screen.

   call function 'CSAP_MAT_BOM_MAINTAIN'
        exporting
             material   = 'MAT100'
             plant      = '0001'
             bom_usage  = '1'
             valid_from = '14.10.1996'
             fl_bom_create = ' '
             fl_new_item = ' '
             i_stko  = tstko
        importing
             fl_warning = flg_warning
             o_stko     = tstk2
        tables
             t_stpo       = tstp3
        exceptions
             others  = 1.
   if sy-subrc eq 1.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
   endif.
   if flg_warning eq 'X'.
*---- Please see log for information, warning messages, and success
*     messages.
   Endif.
 

Hope this helps. Reward points if helpful.

Ya , that's fine ....

But is there any transaction through which we can get this database log .

Hello,

You need to retrieve the GUIDX of the item number from the table STPO and then populate it in the T_STPO structure for the field ID_GUID of the module function.

For me it works. It updates the item line instead of creating a new one.

Plz try it.

To get the messages, you need to use the FM CALO_LOG_READ_MESSAGES.
