Customer and vendor totals statements: The Customer or Vendor Accounting Sum. Rate Tables (KNC1/KNC3 or LFC1/LFC3) do not include the Profit Centre field. Therefore, authorisation control with regard to the profit centre is not possible for evaluations such as the customer and vendor balance lists (transactions FD10N or FK10N).
In the PRGN_CUST table, set the customising switch REF_USER_CHECK to E. This prevents you from using other types of users than reference users. This switch only affects new mappings; You should manually clean up any existing mappings of other user types.
Security in development systems
To make the most of the time stamping process, you should fill the time stamp tables in the legacy system before upgrading. Implement SAP Note 1599128. With this correction, the report SU25_INITIALIZE_TSTMP is delivered, which allows to write the current timestamps of your data from the transaction SU22 into the respective timestamp tables USOBT_TSTMP and USOBX_TSTMP. After the upgrade, you will have a reference date for your SU22 data, which you can use to compare with the SAP proposal data shipped for the new release. Setting the timestamps in the legacy release reduces the effort required to complete step 2a, because only those applications whose SU22 data has been modified are matched. If you have not filled the timestamp tables in the old release, the tables in your new release will be empty. In this case, in step 2a, the content of the SAP proposal values will be compared to the customer proposal values, regardless of a timestamp.
