ISMW Steps in SAP PP
Demystifying ISMW: A Step-by-Step Guide in SAP PP
For those working in production planning with SAP PP, the term ISMW might raise some eyebrows. While it doesn’t have a universally agreed-upon definition within SAP, it often refers to a series of steps involved in replanning a production order. These steps ensure your production plan reflects any changes or updates that might have occurred.
In this blog, we’ll break down the typical ISMW process into a clear, step-by-step guide:
1. Preparation:
- Identify the Production Order: Start by pinpointing the specific production order that requires replanning. You can find this order using the transaction code CO01 or CO03 in SAP PP.
- Gather Information: Before proceeding, collect any relevant information that might affect the replanning process. This could include changes in material availability, updated lead times, or modifications to the bill of materials (BOM).
2. Replanning Execution:
- Transaction Selection: You might use a few transaction codes for replanning, depending on your specific needs. Here are the most common:
- MD04: MRP List. This allows you to reschedule specific materials within the production order.
- MF60: Forecast. Use this to update any forecasting data that might impact the order.
- CO02: Change Production Order. This offers a more comprehensive approach to modifying various aspects of the order.
- Replanning Parameters: Within the chosen transaction, define the replanning scope. This might involve specifying a date range, selecting specific materials, or describing a replanning type (e.g., forward, backward).
- Execution: Once you’ve set the parameters, initiate the replanning process. SAP will analyze the production order based on the defined scope and update the plan accordingly.
3. Post-Replanning Review:
- Results Analysis: After replanning, it is crucial to review the generated results. Check for any rescheduling of operations, changes in planned delivery dates, or material requirement updates.
- Adjustments: If the replanning results aren’t optimal, you should manually adjust them. This could involve modifying lead times, splitting the production order, or expediting material procurement.
4. Documentation:
- Document Changes: It’s good practice to document any significant changes made during the replanning process. This helps maintain a clear audit trail and facilitates future reference.
