Hi Agnibha,

Greetings to you!

targetRecord is the provided record. This attribute will contain only the fields relevant to the requested layoutType and/or fields atributes.

targetFields is a simplified view of the fields in targetRecord, to reference record fields in component markup.

targetFields is the corresponding attribute to simpleRecord. targetFields is easier to use compared to targetRecord. You do not need to use both, just stick with one.

Please refer to the below links which might help you further.

Hi agnibha, According to documentation targetFields contains  simplified view of the fields in targetRecord, to reference record fields in component markup. targetRecord  This attribute will contain only the fields relevant to the requested layoutType and/or fields atributes. From release notes force:recordData includes a new attribute called targetFields, which is populated with a simplified view of the record’s fields. targetFields is automatically updated whenever Lightning Data Service detects a record change.  v.targetFields.Name  is equivalent to v.targetRecord.fields.Name.value. A simple way to update force:recordPreview usage to force:recordData is to change references from targetRecord to targetFields. Both has same data but only difference is syntax for reference With targetFields we can simply reference field like this {!v. targetFields.Name} Using targetRecord we have to reference field in this way {!v.targetRecord.fields.Name.value} Please refer below links which might help you further https://releasenotes.docs.salesforce.com/en-us/summer17/release-notes/rn_lightning_data_service.htm Hope this helps you If this helps kindly mark it as solved so that it may help others in future.
