Configuration (appsettings.json)
- Alexander Dürrstein
General
To maintain the configuration data you have to change the appsettings.json file.
Per default the appsettings.json file is empty.
Every system you want to connect needs its object in the appsetting.json file.
Parameter per system type
RFC & HANA
in this chapter, it is described what to do to maintain the settings for the following connector types:
ECC, BW, S/4HANA, ERP, BW/4HANA, ABAP Relations, HANA
ECC, BW, S/4HANA, ERP, and BW/4HANA, ABAP Relations connectors are named in the following ABAP connectors. In contrast, there are HANA connectors.
If you want to connect to an ABAP connector you can choose between a RFC connection or a HANA connection which will get the information directly from the HANA database below the ABAP connector.
If you decided on the RFC connection you use the properties below BwSystemConfiguations. If you decided on the HANA SQL connection you use the properties below HanaSystemConfiguations.
Explaining the properties:
Property | Meaning | Connector | Example |
|---|---|---|---|
BwSid | The System ID of your BW system | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations | A4H, BI2, S4B, … |
Server | The host or IP address of your HANA database | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations, HANA | |
SystemNumber | The system number of the BW system | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations | 00, 03, … |
Client | The client of the BW system | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations | 001, 800, … |
Prefix | The prefix of the function module for the RFC connection since v1.4.0 you can run the Metadata API without installing a function module. In that case you do not have to set it in appsettings file (more infos here). | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations | Z_, /MYCOMP/Z_, … |
UseAlwaysGetString | DO NOT USE WITHOUT CONSULTNG BLUETELLIGENCE. | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations | true, false |
Database | The database on your HANA tenant where the BW application is located | HANA | HN2, HDB, SYSTEMDB, … |
HanaSchema | The schema where the BW application is located | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations, HANA | SAPBI, SAPA4H, SAPHANADB, … |
HanaSchemaBlacklist | Schemas which should not be analyzed during the process of getting metadata from HANA. It totally make sense to restrict it via the list at least for some technical SAP schemas. | HANA | ["_SYS_AFL", "_SYS_AUDIT", "_SYS_BI", "_SYS_BIC"] |
SqlPort | The SQL Port of your HANA DB. | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations, HANA | 30213 |
UseSsl | If you have set up and want to use an SSL connection to your HANA database. | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations, HANA | true, false |
Languages | List of Languages you want to export | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations, HANA | [ "E", "D" ], [ "E" ], ["D", "C", "F"] |
User | User for the BW Data Lineage API. The user needs full select rights on the HANA schema of the BW system. | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations, HANA | Â |
EncryptedPassword | No manual input. The password must be set via command line (see here). In that case a property EncryptedPassword is stored in the appsettings.json file. If you need to use a clear password, please use the connection string. | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations, HANA | Â |
ErpComponentBlacklist | Blacklist of Application Components in of DDIC tables, views and CDS Entities | ECC, S/4HANA, ERP | Recommended to start with a bigger blacklist in the beginning "ErpComponentBlacklist": [ |
CustomReportsFilter | Filter on the table PROGNAME | ABAP Relations | PROGNAME NOT LIKE '/1BCF41/%' AND PROGNAME NOT LIKE '/1BCWDY/%' AND PROGNAME NOT LIKE 'GP%' AND SUBC <> 'F' AND UNAM NOT LIKE 'SAP%' AND UNAM <> '' |
SplitFilesChunckSize | Chunck size to split the Details, Buildups, and BuildupDescriptions file to multiple files by a number of entities. 0 - default. Output 1 file | BW, BW/4HANA, ECC, S/4HANA, ERP, ABAP Relations, HANA | 0, 10000, 1000000 |
Connection String for HANA Connection
Instead of using the delivered content of the appsettings.json file, you can use a connection string if you need to set more properties for your HANA database. That is important if you use e.g. proxy servers and users.
For more detailed information you can visit the SAP guide.
Example of ConnectionString:
If you do not insert a password in the connection string you can also set an encrypted password via command line (see here).
SAC
Property | Meaning | Connector | Example |
|---|---|---|---|
Url | URL of the SAC instance | SAC | |
TokenUrl | Token URL of the SAC instance | SAC | https://mysacinstance.authentication.eu10.hana.ondemand.com/oauth/token |
ClientId | Client ID for the OAuth Authentication in SAC | SAC | Â |
EncryptedSecret | SAC | true, false | |
ExcludePrivateObjects | Handle if the private SAC entities should be included or excluded | SAC | Â |
Datasphere
Property | Meaning | Connector | Example |
|---|---|---|---|
AuthorizationUrl | Authorization URL of the Datasphere Instance | Datasphere | Â |
Url | URL of the Datasphere instance | Datasphere | |
TokenUrl | Token URL of the Datasphere instance | Datasphere | https://mydspinstance.authentication.eu10.hana.ondemand.com/oauth/token |
ClientId | Client ID for the OAuth Authentication in Datasphere | Datasphere | Â |
RedirectUrl | Redirect URL | Datasphere | |
EncryptedSecret | Datasphere | true, false |
Connection properties for upload
If you want to upload the file directly to a platform you need to maintain the parameters to upload your metadata.
