We have configuration done for custom bapi in sap. Connector we are aggregate default standard attribute. But when we configured custom bapi function name.
You’re passing a null value when it should be expecting a String, (I guess, your table name). Wherever you’re invoking it make sure you’re passing that paremeter, either in code or within the UI
Is this the aggregation BAPI or a BAPI to pull extra attributes?
Looks like your BAPI is expecting inputs that aren’t being provided by SailPoint, or the BAPI was not set up according to the SailPoint configs.
Also, ask the SAP team to check the logs, there may be a missing permission to access extra data beyond what the default service account permissions are. As an example, if you are accessing InfoTypes outside of the ones that are supported OOTB by the connector, your service account will need extra permissions to access the data on those infotypes.
