Record Field Id

Question

Hi everyone , 
 I have scenario where my data is stored in Map/Dictionary. 
 Now this has to be stored in record. Each field to be mapped with the respective record field. Considering the volume, Is there a way to use the Field Id to map the value. Example: 
 a!localvariables( 
 local!list:{ { columnName:"Name", recordFieldId"4567898765" }, 
 { columnName:"Desc", recordFieldId"4567856894" }, /* Now the data to be mapped */ a!foreach( locaL!list, index(record,fv!item.recordFieldId,null) ) 
 )

No, you cannot use Field IDs to dynamically map data to records. /* Method 1: Direct casting (recommended for volume) */
cast(
 recordType!YourRecord,
 local!mapData
)

/* Method 2: Using record constructor */
recordType!YourRecord(
 recordType!YourRecord.fields.name: local!mapData.name,
 recordType!YourRecord.fields.desc: local!mapData.desc
)

/* For Bulk Operation */

a!forEach(
 items: local!listOfMaps,
 expression: cast(recordType!YourRecord, fv!item)
)
 Field IDs are internal and not accessible for dynamic referencing. Use field references with dot notation instead.

Have you considered making a dictionary/map mapping the fieldName to the recordField to store the mappings and then using that for the copy? This would allow you to have recordFields using relationships.

When field names differ between source and record, you must manually map each field using recordType!Record.fields.fieldName: sourceData.differentName.
Direct casting only works when field names match exactly. Related records require separate handling after parent records are created.
