Multiple Usage unchecked but shadow table still updated with IUUC_PROCESSED = 0

Hello,

We changed several MT_IDs by unchecking the Multiple Usage checkbox:

The OLI functions have been redesigned correctly and all Run Time Objects also. The IUUC_PROCESSED field is now conditioned to empty in the Abap statements:

*** get records from logging table

SELECT * FROM /1CADMC/00001360 CLIENT SPECIFIED

  INTO TABLE _IT_IO_S_/1CADMC/00001360 UP TO I_NUM_OF_RECORDS ROWS

  WHERE (_WC_S_/1CADMC/00001360)

   AND IUUC_PROCESSED = ' '

  ORDER BY

    IUUC_PROCESSED

TABNAME

VARKEY

IUUC_SEQUENCE

%_HINTS MSSQLNT 'TABLE &TABLE& abindex(IUC), READCOMMITTED,READPAST'.

However the records in the table are still updated with IUUC_PROCESSED equals to 0:

We use DB6 09.07.0005 and ECC 6.0 with DMIS 2011_1_731 0004 SAPK-11604INDMIS DMIS 2011_1.

Any idea?

Regards,

Laurent
