MOQ & order type relation

Dear Guru's

As we all aware of the MOQ (Minimum Order quantity) flows from the sales: Sales org data of Material master , Now my client has the requirement of Materials ordering through two different order types (both are standard orders)

• Over the counter sales
• Sales to dealer.

Now i need two different MOQ's for the same part numbers with the different Order types relation.How to relate Order type & MOQ.in standard
