Question

Hi,
I have a requirment of extending vendor master data (Companycode data and Purchasing Organization data ) through Tcode XK02 using LSMW.Also I need to generate an error log file for validating the data from flat file and  must have an export option of the error log file.
Can you help me how to proceed on this in steps.

Based on the selection criteria I need to maintain two source structues,one for companycode data and the other for Purchasing Orgnization data for uploading  data thru LSMW.How to do this?

Answer 1

Hi,
create 2 LSMW object (under same project and subproject)..
one for extended vendor master data for company code data and other for  extended purchase organization data for company code data.
Now check the radio buttons and based on that populate ur LSMW object.
Store project
  project = < >.
Store subproject
  subproj = < >.
Store object
  object  = '6GSC022_TS3'.
if r_ccode = 'X'.
Store object
  object  = < >.
else.
Store object
  object  = < >.
endif.
Call the function module to display object (LSMW) maintenance screen
  CALL FUNCTION '/SAPDMC/LSM_OBJ_STARTER'
    EXPORTING
      project        = project
      subproj        = subproj
      object         = object
    EXCEPTIONS
      no_such_object = 1
      OTHERS         = 2.
Generating error log:
After the checking the field if u think for this u need to generate error message then In the Maintain Field Mapping and Conversion Rules option under the required field write the following code:
data: v_msgtxt(100) type c.
message  <msg ID>    <message type>   <message no>
                 with   <var1>  <var2>
                 into v_msgtxt.
write v_msgtxt.
Follow the next step in LSMW object till you reach the option  Convert Data.
After you execute this option you will get the desired message here.
