From the SAP APO easy access menu, choose  Master Data Production Process Model SNP PPM Generation: Determine Mode Combinations . The Select Worklist screen appears.

In the upper part of the screen, specify a PP/DS PPM plan or range of PP/DS plans that you want to convert into SNP PPM plans using the SNP Generation with Lot Size Margin function (you can also choose PP/DS plans by entering one or more products or location products). Alternatively, in the lower part of the screen, you specify SNP plans that have already been generated with the SNP PPM Generation with Lot Size Margin function, which you want to change and flag to be run in a new generation report run.

Choose . The Mode Combinations for Generation of SNP Plans screen appears.

The PPM plans you selected in the selection screen are displayed in the upper table.

You first specify a name in the SNP Plan field. If you give a name without a placeholder, the system provides the appropriate SNP plan number at the end of this name (such as SNP Plan01 and SNP Plan02) when generating multiple SNP plans for one PP/DS plans (one SNP plan is generated per PP/DS plan mode combination). However, you can also add the placeholder # at the end of the name or insert it at any point in the name. If you choose this option, the system replaces the placeholder with the relevant number. You can also leave the field blank and use the SNP Name button to have the name automatically generated by the system. It is formed like this: Name of PP/DS Plan_SNP (if required +_Number ) .

In the Generated field, you are shown whether the SNP plan has already been generated from the PP/DS plan manually or automatically (which means with or without manual mode combination determination) using the SNP PPM Generation with Lot Size Margin function.

In the other fields from the upper table, you specify parameters to control SNP PPM Generation that can be maintained both in this function and in the SNP PPM Generation with Lot Size Margin function. If you enter values in the corresponding fields in this function, these values overwrite the corresponding entry in the generation report selection screen, if you leave the report fields PP/DS plan number and SNP plan number blank. For more information on these parameters, see SNP PPM Generation with Lot Size Margin or the corresponding F1 help.

If you double click on a PP/DS plan, the operations and activities of this plan are displayed in the lower table. It is now possible to use the selection help to choose a specific mode for each activity. You can only choose one mode per activity as only one mode is valid per activity in an SNP PPM. When the SNP PPM Generation with Lot Size Margin function is run at a later point, exactly one SNP PPM is generated for the PP/DS PPM mode combination chosen.

You can run checks on the validity of mode combinations and the maximum number of SNP plans generated.

If you choose , the system checks whether valid mode combinations exist and whether all the mode combinations chosen are valid. Negative check results (displayed in the table in the form of the icon and an error message), can be caused by the fact that the mode combinations are now no longer valid due to a subsequent change to the PP/DS mode combinations or that no valid mode combinations exist because a lowest mode priority has been specified.

If you choose Maximum Number , a check is made to see whether the number of SNP plans to be generated exceeds the value entered in the Maximum Number field (the generation report does not terminate if this value is exceeded). If the value is exceeded, you can restrict the number by choosing the lowest mode priority, for example, or by specifying a specific mode combination.

After you have entered the mode combinations, choose Adopt . The system saves your selection and generates a name for the corresponding SNP plan (for rules, see above). If you choose Cancel , your changes are undone.

Set the Flag indicator for the PP/DS plan. If you set the indicator, the PP/DS plan will be taken into account in the next run of the generation report. By pressing the Flags button, you can set or delete all flags automatically.
