AppendMatrixFieldToKeyName

In some datadefs, AppendMatrixFieldToKeyName is used to allow searching for a record containing a particular matrix field, without having to loop through the rows. For example, POVc has this index:


SubsetKeyBegin2(ActArtCodeOSFlag);

StoreInBaseKey;
AppendMatrixFieldToKeyName(ArtCode,0);
KeySegment(SerNr);


I have written a procedure which loops through POVc looking for those containing a specific item, but it returns no results even though I have a purchase order with the specified item. Below is the code I am using. Any idea what might be wrong?

TrHs = true;
index = "ActArtCodeOSFlag:" & INr.Code;
ResetLoop(POr);
while (LoopKey(index,POr,1,TrHs)) begin
if (TrHs) then begin

trace(POr.SerNr,POr.TransDate);


Thanks

Paul
