SAP Message CC041 - Information on trace log

Using the trace log
The trace log tells you which conditions the change statuses of theobjects are effective under. This information is particularly helpfulwhen you are dealing with complex changes so that you can follow up whychange objects with a certain change status are selected.
The log is created for the following change conditions:

  • Changes with date effectrivity (Valid-from date)

  • Changes with parameter effectivity (for example, serial no.
    • effectivity)

    Activating the function
    You can switch the trace log on and off in the Engineering ChangeManagement menu (Environment -> Trace on/off).

    The log shows whether the following indicators are set under controldata in Customizing
    Parameter effectivity is active
    Release is active
    Rank is active
    Depending on whether an indicator is set or not, the appropriate datais displayed in the list of change numbers. If, for example, theRank is active indicator is set, the list contains theRank field.
    Assigning values to the parameters
    The system lists all the effectivity parameters thathave values assigned to them in the current processing situation.
    The value assignment can have taken place as follows:

    • User entry (Parameter entry dialog box)

      • Example: material D7000 and serial number 200
      • Automatic derivation from the change number

        • List of change numbers
        The system lists all the change numbers that the object has beenprocessed with.
        You receive the following information for each change master record:
        • Display key for release and selection

          • You can use this function to determine the color of the display for therelease status and selection.
          For example, the choice of color shows whether a change number iseffective and has been selected because of its release key. The systemalso takes into account whether you have just simulated the valueassignment for the effectivity as default entry.
          • Effectivity data

            • This function shows which conditions a change with reference to acertain change number is effective under.
            You can make the foillowing entries:
            Valid-from date for a change master record that has beenmaintained with date effectivity
            Parameters and their values for a change master record that youhave maintained with parameter effectivity
            Example:
            Change master record with effectivity type SERNR (serial no. interval)
            The effectivity data shows the material number and the upper and lowerlimits of the serial number interval
            • Effectivity type

            • Priority (Pr)

            • Rank

            • Internal counter

              • Multi-level nesting of the trace log
              You receive a multi-level trace log in the following processingsituations:

              • You are processing a hierarchical object (for example, a level-by-level
                • BOM, a multi-level BOM). The object has been processed with referenceto change numbers on several explosion levels.
                • At least one change number has been determined on the uppermost
                  • explosion level and its effectivity data is the same as the values forthe effectivity parameters (for example, Parameter effectivitydialog box).
                  The log is created with the same outline for each explosion level.
                  Selecting a valid change number
                  If the effectivity data of more than one change number coincides withthe values assigned to the effectivity parameters, the system checksthe priority (Pr).
                  The change number with
                  • the highest priority is selected as being effective.

                    • This change number is shown in the key as follows: Change number iseffective and has been selected (shown in yellow in the standardsystem).
                    • a lower priority is shown as being a valid change number but the
                      • changes made with reference to this change number are not takeninto account in the explosion.
                      This change number is shown in the key as follows: Change number isvalid and has not been selected (shown in green in the standardsystem).
                      Calling the next explosion level
                      If at least one valid change number has been selected for the currentexplosion level (shown in yellow in the standard system), the explosioncan be carried on in the next explosion level with the Continuefunction.
