Monash require to write back UserID, Email and MonashPersonID as below:

• Subtype 9008, is for FIM SAP interface on user ID and email address. Field mapping:
  Field Name Data Type length
  User ID ZZFIMINT Characters 30
  Email USRID_LONG Characters 241

• Subtype 9009, is for Monash Person ID. Field Mapping :
  Field Name Data Type length
  Monash Person ID USRID_LONG Characters 241

When trying to test the write back permission using the SAP harness, the infotype update function does not allow to specify subtype.

In order to prevent lots of scrolling on the adapter schema pages, allow collapsing of non-key fields.

An alternative to having to change batch size/timeout settings on export, it might be worth considering adopting a similar approach that Microsoft did with the MIM (Service) MA - i.e. changing the default option to asynchronous instead of synchronous exports.

Under the current default configuration, the MIM MA gets a success returned from the MIM Service once an exported change has been successfully queued (inserted in the REQUEST - either single or batch request objects). A similar approach might be worth considering for IdB such that we can decouple long-running connector export times from the MIM export itself.

I am categorising this request under O365 because that is where I am seeing the most need for this feature right now - however this would be a generic option.
