SAP Production Planning Table

With these three parameters, it is possible that you can set it up correctly in your system
to enable the appropriate planning of your material requirement.
Do you have a SAP PP Question?
Purchasing processing Time - OPPQ
Please refer above subject and would like to do following. External Processing Time
I have set in using OPPQ. My client want this time set differently for different
Vendor. Is there any userexit or customization settings?
For MRP to take lead time by supplier, you need to have 3 settings:
1) The config in OPPQ - External procurement at plant level (or OPPR at MRP grp -
Scheduling/doc. type) should have the check box marked to read
SchedAgreem/Inforecord leadtime (T399D-GTERM)
2) You should have a contract/schedule agreement, or a purchase info record maintained
for that plant-material-vendor combination
3) You should maintain source list (ME01) for the contract/schedule agreement, or info
record. This changes the default behavior of MRP to use leadtime by supplier, rather than
material master leadtime. When both contract and info record exist, the contract will take
precedence.
Please watchout for the case if you're already using contracts/info records in
procurement, but not using them for planning. In this case your leadtime data in these
documents may be incorrect, or may be left blank - this will be interpreted as zero if you
make this change implementation, as mentioned in the steps above.

You define per plant and per MRP group the percentage of the safety stock that is to be
available for planning. This helps to avoid a situation where order proposals are created
unnecessarily by the system to cover small shortage quantities.
For example:
