Description of the Interface
The interface for data interchange is based on the Business Application Interfaces (BAPIs) of MM Materials Management. It enables you to exchange the following objects:
Service master records
Purchase orders
Contracts
Service entry sheets
The data is converted from an external format into the SAP format or vice-versa with the aid of the SAP enhancement SRVESI. This allows you to adjust the data format to suit your requirements.
A precondition is that you must activate the SAP enhancement SRVESI in Customizing.
Data interchange is still possible if you do not activate this enhancement, but in this case the system automatically uses a predefined data format .
Predefined Data Format
The predefined data format is also oriented on the Business Application Interface (BAPI) for external service documents (e.g. BAPI_REQUISITION_CREATE) and the SAP data model.
Record Types
The user data is exchanged in the form of data records whose structures are defined in the SAP Data Dictionary. Each structure is uniquely assigned to a record type:
DDIC structure |
Record Type |
Description |
BAPI_STAT |
0 |
Status record |
BAPI_MDRV |

Header/item data, purch. doc. |
(RFQ, quote, PO, contract) |

Data Model
The SAP data records are linked in accordance with the SAP data model.
You can access detailed information on the SAP data model (graphical display, data records, fields) within the SAP development environment using the SAP transaction SD11.
The following list contains the most important assignment rules for the data records:

Data Carrier Format
The file is organized sequentially.
The data records are outputted in ASCII format.
The data carrier record length is 78 bytes.
Each data carrier data record ends with the character ‘>’.
SAP data records with a length of more than 78 characters are divided among several data carrier records. The continuation character is ‘>’.
The following data record description results:
Character |
Contents |
1 |
Record type or continuation character |
2-77 |
User data |
78 |
End character |
Note
It was decided to limit the data carrier record length to 78 characters to facilitate secure transmission of the data via Internet mail.
Interface ID
Each transfer file starts with the data record BAPI_STAT. The specific instances of the fields SATZART and MARK are predefined.
SATZART ‘0’
MARK ‘SAP R/3’.
All other fields in the structure are for information and are at your disposal.
