Phased implementation of SAP ERP

Hello experts , Whether it is possible to activate only External Service Management (ESM) & SD without activating MM module fully?

Is it feasible technically to activate MM separately as second phase. regards nallasivan

    Implementation of the SD modules without implementing MM module is possible but because of the following link it is not advisable to implement SD without MM:

    Link Between MM and SD

    1. When you create sales order in SD, all the details of the items are copied from Material master of MM.

    2. MRP and availability check related data is also taken from MM although you control this data in SD also.

    3. While you create inbound/outbound delivery with reference to a sales order, the shipping point determination takes place with the help of the loading group, plant data, shipping conditions etc. This also refers to Material Master.

    4. The material which you are entering in a sales order must be extended to the sales area of your sales order/customer otherwise you cannot transact with this material.

    There are many such links between SD and MM.

    Again the next query implementing ESM without MM

    MM External Services Management is integrated into the Purchasing application within the Materials Management module, and indicates the interfaces to other applications.

    MM External Services Management (MM SRV) is an application component within the Materials Management (MM) module. It supports the complete cycle of bid invitation, award/order placement phase, and acceptance of services, as well as the invoice verification process.

    MM External Services Management is completely integrated into the Materials Management system. The master data for the procurement of services can be stored in service master records, for example, which subsequently provide default data for the purchasing documents. Service specifications for a concrete procurement project are not created and processed separately each time (e.g. as bid invitation or contract specifications), but entered directly in the purchasing documents (e.g. in a request for quotation, quotation, purchase order or contract).

    dear nallasivan, MM and SD modules are independant modules and can be activated separately. But FI module is required for both MM and SD modules to carry out all financial accounting requirments. All the relevant data from any third party softward can be loaded into sap to complete the transactions in FI modules. n.selvakumar.
