About bdc using session method

Question

how to update mm thru mk01. please provide the source code with a flat file to be updated.
it's urgent.

Answer 1

Well, you can go do the following steps:
1. Go to SHDB, create a new recording session for the t-code mk01.
2. Go though the t-code and create an entry and complete the transaction.
3. Once that's done, it will record everthing, save and transfer it to a program.
4. Go to the program in change mode, upload the flat file into a internal table using FM 'upload' or 'gui_upload'.
5. Use the internal table to populate further interies into the tcode.
Please go through the following link to understand the process better:

   DO NOT CHANGE - the generated data section - DO NOT CHANGE    ***
  If it is nessesary to change the data section use the rules:
  1.) Each definition of a field exists of two lines
  2.) The first line shows exactly the comment
      '* data element: ' followed with the data element
      which describes the field.
      If you don't have a data element use the
      comment without a data element name
  3.) The second line shows the fieldname of the
      structure, the fieldname must consist of
      a fieldname and optional the character '_' and
      three numbers and the field length in brackets
  4.) Each field must be type C.
