Hi Shailaja,
For Posting details from MII(from MES) to SAP we will use different BAPI's ...
E.g: For Order Confirmation we will use BAPI's like BAPI_PROCORDCONF_CREATE_TT for Process order Confirmation and BAPI_PRODORDCONF_CREATE_TT for Production Order Conformation .
I think in your scenario requirement is for order confirmation , so you can use either BAPI_PROCORDCONF_CREATE_TT or BAPI_PRODORDCONF_CREATE_TT based on your requirement .
For Field Mapping in BAPI's , you can find all the description of BAP's fields in ECC with T-code of SE37 or SE80, how ever please find the field mapping details below ...
Available Input Table Stricture in BAPI BAPI_PROCORDCONF_CREATE_TT:
In this BAPI we have to map input fields(from MES) to GOODSMOVEMENTS structure under the BAPI, fields Available in GOODSMOVEMENTS structure is like below ... for Each field has its own description which is very easy to understand and map the suitable input field to this fields ... The Description of fields is like below ...
Material: Material NUmber, Plant: Plant Number , Stg_Loc: Storage Location, Batch: Batch Number, Move_Type: Movement Type, Stck_Type:Stock Type, Spec_Stock:Specification/Special Stock, Vendor: Vendor Name, Customer: Customer Name, Sales_ord: Sales Order Number, S_Ord_Item: Sales Order Item, Sched_Type: Schedule Type, Val_Type:Value Type, Entry_Qntry:Entry Quanity, Entry_UOM: Entry Unit of Measurement, Entry_UOM_ISO: Entry Unit of Measurement as Per ISO, PO_PR_QNT: Process Order Print Quantity, ORDERPR_UN: Order Price Unit, ORDERPR_UN_ISO: Order Price Unit as per ISO etc ... like wise for other fields description you can find it easily by comparing fields in MES with fields in ECC ....
Here you can found more than or near 50 fields in GOODSMOVEMENT structure map the desired fields in MES with GOODSMOVEMENT fields ... after thsi you have to map some more fields in another structure like below ... LINK_CONF_GOODSMOV
Like wise for BAPI_PRODORDCONF_CREATE_TT BAPI also need to follow the same steps ...
I hope this information will help you developing your scenario ...if you need any information let me know ...
