SNP PPM Generation Without Lot Size Margin

Use

This involves generating an SNP production process model (PPM) from an existing PP/DS PPM. Note that this concerns this PPM constellation only. In this process, all SNP-relevant product and resource consumptions from the existing PP/DS PPM are determined for a lot size and grouped together into SNP operations and activities. If you wish to generate SNP PPMs from PP/DS PPMs for lot size margins and several mode combinations of a PP/DS PPM, use the generation report SNP PPM Generation With Lot Size Margin .

To call up the SNP PPM Generation Without Lot Size Margin generation report , choose Start of the navigation path Master Data Next navigation step Production Process Model SNP PPM Generation Without Lot Size Margin End of the navigation path from the SAP APO Easy Access menu .

Prerequisites

To be able to generate and to use the transaction, you must note the following points:

You have an active PP/DS PPM.
The SNP PPM is generated exclusively for the specified lot size, since no variable durations or consumptions can be taken into account.
In the generation process, only single or multi-mixed resources for which the Not SNP Rel. indicator has not been set on the Planning Parameters tab page are taken into account. In addition, only those products for which the SDPrelevance indicator has been activated on the Properties tab page of the product master data are taken into account.
Operations and activities in the SNP PPM do not necessarily match those of the PP/DS PPM from which they were generated. The reason for this is that activities and operations that are contained in non-relevant resources or components are omitted, or are grouped together with other activities in a time bucket because of short duration.

Activities

Using the plan or PPM entered and the lot size, an order is dispatched infinitely to liveCache (without taking into account resource schedules that possibly exist).
Using a time bucket, consumption of the SNP-relevant resources and components can be determined per SNP bucket and grouped together into SNP operations or SNP activities.

Note Note

Only the valid components and the mode, which is selected automatically via the order explosion, are relevant for generating the SNP PPM.

End of the note.

Consecutive consumptions of the same type are consolidated into one activity, while bucket durations and material consumptions are added together.

If a new component or resource is added to, or removed from a bucket in an SNP PPM, a new activity is generated in this SNP PPM.

If there is a change of primary resource, the system generates a new operation. If several PP/DS activities with different primary resources lie within an SNP bucket, the system checks the resources to see whether the dimensions are the same. The primary resource for the SNP mode is then determined from the PP/DS activity with the highest resource consumption.

Data from the setup matrix is only relevant if the Setup indicator has been set for a setup activity.

Only fixed consumptions and durations can be generated within the SNP plan, because the consumptions arising are determined via a dummy order (fixed lot size). However, if the SNP PPMs generated are also to be valid for lot size margins, the variable portions must likewise be manually calculated out of the fixed portions (see also SNP PPM Generation With Lot Size Margin ).

In calculating the bucket consumption, the planned delivery time is also considered. If, for example, a planned delivery time of one day has been specified, the system generates a wait activity for this time. If a PPM is generated in the past, the days up to the generation date are consolidated to form a wait activity.

After generation, you must manually maintain the following texts:

Plan
Product plan assignment
Operation
Activity

This manual maintenance is necessary because the texts cannot be adopted from the PP/DS PPM automatically.
