Intro
Most asked question in SAP Interviews and Exams. May all know but let us compile it.
Main part.
Take reference from these Q&A1, Q&A2
PIR Consumption: Sales order consume PIR quantity in MD04 screen. No table updated in MD61. See the below difference.
PIR Reduction: GI or GR reduces PIR quantity in MD61. Table will be updated in MD61 and increases the withdrawal quantity automaticaly in background.
| Planning Strategy | PIR Consumption (When) | PIR Reduction (When) | Mandatory "Mixed MRP" |
| 10 | No Consumption of PIR against incoming sales order | When goods issue or delivery done for sale order (601 Movement Type-PGI) according to consumption mode & period maintained in material master | NA |
| 11 | No Consumption of PIR against incoming sales order | When GR (101 movement type) is done for production order according to consumption mode & period maintained in material master | YES. Mixed MRP = 2. |
| 20 | No PIR, So No Consumption | NOT APPLICABLE | NA |
| 40 | When sales order is entered | When delivery (PGI) is posted against the sale order (601 movement type) according to consumption mode & consuption period maintained in MMR | NA |
| 50 | When sales order is entered | When delivery (PGI) is posted against the sale order (601 movement type) according to consumption mode & consuption period maintained in MMR | NA |
Factors affecting the Consumption and reduction
Both consumption and reduction are affected by the parameters like consumption mode and period in days maintained in the mrp 3 view of material master and it have the highest priority. If you do not specify a consumption mode, the system uses the consumption parameters from the MRP group that is assigned to the material. If a consumption mode is not specified there, the consumption mode is set to '1' by default (backward consumption only) with a (backward) consumption period of 999 days. This means that the consumption cannot be deactivated
PIR Consumption Example:
Consumption Mode (Back & Forward) and Period 100 days, Strategy 40:
Created a PIR of 10 PC.
PIR quantiy got consumed by new sales order of 1 pc and changed to 9 pc.
But in MD63 you can see that there are no changes as PIR remains 10 pc.
PIR Reduction Example:
Same material with same master data like consumption mode and period. But here I have created a delivery for the sales order and posted goods issue via VL01N. This reduced the PIR in MD63 itself.
MD04 after PGI
Some configurations that affect the consumption and reduction:
OVZG setting for req.class 030: Independent requirement reduction indicator set.
OPPS (Planning strategy 40)
OMJJ
Conclusion:
Please have a look on link to get idea on demand flow from sales order to production.
