No way to differentiate between RecordRef.Copy when using Variant

[navdotnetreqs]

When using a variant for generic code, there doesn't seem to be a way to differentiate between overloaded RecordRef.Copy()-function calls.

If the variant was a recordref, I could do

sourcerecref:=variant;
recordref.copy(sourcerecref);

But in this case the variant is a Record, which is precisely why I need recref.copy.

"The call is ambiguous between the method 'Copy(var Table, [Boolean])' defined in Class 'RecordRef' by the extension '' and the method 'Copy(RecordRef, [Boolean])' defined in Class 'RecordRef' by the extension ''.AL[AL0196]"

A type "Table" does not exist and we cannot do a cast, so this can probably not be done unless the Copy-function is split into two..?

This probably requires a new overload for the copy function to handle the record. There's no generic record type to cast to

Hi, I think what you are looking for is this:

var
     MyTable: Record "My Table";
     MyTableRecordRef: RecordRef;

MyTableRecordRef.GetTable(MyTable);

GetTable is equivalent to Copy.

This works with both normal records and temporary records (table gets shared). Expand to see the code.

```al table 50100 "My Table" { fields { field(1; K; Integer) { } } } report 50100 "Test My Table" { UsageCategory = Tasks; ApplicationArea = All; ProcessingOnly = true; trigger OnPreReport() var MyTable: Record "My Table"; TempMyTable: Record "My Table" temporary; begin GlobalLanguage(1033); MyTable.Reset(); MyTable.DeleteAll(true); MyTable.Init(); MyTable.K := 1; MyTable.Insert(true); MyTable.Init(); MyTable.K := 2; MyTable.Insert(true); MyTable.Mark(true); MyTable.Init(); MyTable.K := 3; MyTable.Insert(true); MyTable.Mark(true); MyTable.SetFilter(K, '>%1', 0); MyTable.MarkedOnly(true); TempMyTable.Init(); TempMyTable.K := -1; TempMyTable.Insert(true); TempMyTable.Init(); TempMyTable.K := -2; TempMyTable.Insert(true); TempMyTable.Mark(true); TempMyTable.Init(); TempMyTable.K := -3; TempMyTable.Insert(true); TempMyTable.Mark(true); TempMyTable.Init(); TempMyTable.K := -4; TempMyTable.Insert(true); TempMyTable.Mark(true); TempMyTable.SetFilter(K, '<%1', 0); TempMyTable.MarkedOnly(true); Message( 'Normal: %1\\Temporary: %2', GetRecordInfo(MyTable), GetRecordInfo(TempMyTable)); end; local procedure GetRecordInfo( RecordVariant: Variant): Text var _RecordRef: RecordRef; begin _RecordRef.GetTable(RecordVariant); exit(StrSubstNo( 'IsTemporary: %1; Count: %2; Filters: %3', _RecordRef.IsTemporary, _RecordRef.Count, _RecordRef.GetFilters())); end; } ``` Output: ``` Normal: IsTemporary: No; Count: 2; Filters: Marked: Yes, K: >0 Temporary: IsTemporary: Yes; Count: 3; Filters: Marked: Yes, K: <0 ```
