Introduction
This plugin would allow SAP ECC enterprise users to specify one of the Inventory Management data sources as source in Cloud Data Fusion. Typical pipeline scenario would include specifying one of the data sources as source (under Sources plugins) and BigQuery as sink. For the sake of simplicity, this document will cover one data source (Material Movements from Inventory Management - 2LIS_03_BF).
User Experience and Configuration
- SAP ECC Setup
SAP ECC users log into SAP Gateway Service Builder (segw) to create and expose the data source as SAP OData service. SAP has published following articles around this step:
User creates OData service for the data source (2LIS_03_BF). Output is RESTful OData service that can be accessed by Cloud Data Fusion.
User can also use SAP Netweaver Gateway client to test the service (with HTTP request and response)
...
Data type mismatch - OData output has data types (section 6) different than the data types available in BigQuery. Some sort of data type conversion needs to happen before the extracted data can be ingested into BigQuery. Below is the suggested mapping of OData data types to CDAP schema data types:
...
EDM primitive type | CDAP Schema Data Type | Comment |
|---|---|---|
| Edm.Binary | bytes | |
Edm.Boolean | boolean | |
Edm.Byte | int | Unsigned 8-bit integer value |
Edm.DateTime | timestamp | Datetime in the following format: 'yyyy-mm-ddThh:mm[:ss[.fffffff]]' |
Edm.Decimal | decimal | |
Edm.Double | double | |
Edm.Single | float | |
Edm.Guid | string | |
Edm.Int16 | int | |
Edm.Int32 | int | |
Edm.Int64 | long | |
Edm.SByte | int | Represents a signed 8-bit integer value |
Edm.String | string | |
Edm.Time | time | Represents the time of day with values ranging from 0:00:00.x to 23:59:59.y, where x and y depend upon the precision |
Edm.DateTimeOffset | timestampstring | Represents date and time as an Offset in minutes from GMT, with values ranging from 12:00:00 midnight, January 1, 1753 A.D. through 11:59:59 P.M, December 9999 A.D Example 1: 2002-10-10T17:00:00Z Mapped to string to avoid timezone information loss. |
