JR42181: DOUBLING OF SUMMARIZED LENGTH OF ALL COLUMNS OF THE TABLE IN ABAP CODE IF THE ABAP PROGRAM IS RE-GENERATED

APAR status

• Closed as program error.

Error description

• The doubling of summarized length of all columns of the table
  that are extracted ( here is 130) if the ABAP program gets
  re-registed or reloaded to SAP issue has been reproduced in
  house.
     IF D_LEN < 16000.
           D_PACK+D_OFFSET(130) = IT_1.
           D_OFFSET = D_OFFSET + 130.
           D_LEN = D_OFFSET + 130.
           CLEAR IT_1.
           REFRESH IT_1.
  

Local fix

• Workaround: re-select the table first, re-build,
  and re-generate the ABAP program for jobs in question. Takes 5
  min per a job including re-compilation.
  

Problem summary

•   The 'Build SQL query' ABAP code generator generates incorrect
  ABAP code when the ABAP program is cleared and regenerated.
    The generated ABAP code uses a constant that is computed as
  the sum of the length of all fields of the SAP table that
    is extracted. When the ABAP program is cleared and
  regenerated, this constant is doubled, which may result in field
  length
    corruption of the extracted data. The issue only occurs if RFC
  transfer method is used.
  
  The doubling of summarized length of all columns will lead to
  data corruption when the data is extracted from SAP.
  

Problem conclusion

• Patch JR42181 modifies the ABAP code generator. The constant
  that is used in the ABAP code will not be doubled anymore.
    You need to regenerate already exising ABAP code. Clear the
  program in the ABAP stage. Rebuild
    the SQL query by reselecting the respective ABAP table and the
  corresponding columns and regenerate the ABAP code.
