PR generated from MRP run exceeded maximum lot size

Hi gurus,

Need some guidance on the scenario below :

MRP run for material A

MRP type : VB

Lot size: EX

Maximum Lot Size : 200

Material A is a component of material Z. From a previous planned order of material Z, the requirement quantity of material A is 5000.

Now, after the MRP run for material A was done, a PR was generated with quantity of 5000.

My question is why was the PR generated with the requirement quantity of 5000 and not only did not obey the maximum lot size but exceeded it as well?

    On the customizing transaction OMI4 it is possible to define if the maximum stock level will be calculated before or after covering the requirements. Depending on this setting, the replenishment proposal quantity may exceed the maximum quantity.

      No problem! Yes, I am very sure that the PR was created by MRP and sure - I will attach screenshots when I get home.

      What I'm suspecting is that the requirement from a sales order is causing the material to exceed the maximum lot size during the MRP run. What do you think of this? Is this entirely possible?

    Luke, as per knowledge if you have requirement for 5000 system will create PR for 5000 but you have Max lot size in place, it may be multiple of 200 in each line item or separate PRs. Please share screen shots to understand your setup in material master.
