MS Excel VBA Match Function

>Can Match be used on two multidirectional arrays?

If you mean multi-dimensional arrays then no.

>Why am I getting a "type-mismatch" when both arrays show the search as being variant\string in the "watch" area?

The first parameter must be a single variable. What is ReportArray(x, 1)?

The second parameter has to be a single dimension array.

I'm increasing the points.

If Match can't be used on two multi-dimensional arrays, what function can I use to locate the position of the matching record in the second array (ProdArray) based on matching of ID.  
ReportArray(x,1) is the single variable in the first array and position 1 is where the ID stored.

The ultimate goal is to build ReportArray with the data necessary to generate the report with data from different workbooks including modifying some of the data based on various criteria.

I'm not so sure. This will return the position of "fred" in the third column of Range A1:E5

MsgBox Application.Match("fred", Application.Index(Range("A1:E5"), 0, 3), 0)

I take no credit for this - somebody else's bright idea. Don't know if that's what you are after anyway.

StephenJR - I don't think that would work since I am working with arrays not a workbook range - that is, unless I am missing something in your suggestion

You could substitute an array for Range("A1:E5").

Have you thought about using the Dictionary scripting object?  You can load the dictionary with the ID's as the keys and reference whatever data you want based on that key - no "MATCH"ing required.

VBA will easily loop through the members of a dictionary using the FOR EACH construct.

Much more flexible than arrays.

This is quite interesting.  Finding a match in one array against another - beats the heck out of looping throught the second array.

Any comments on efficiency from anyone?

PS - Not for points, please, but in your original code (and I know it will be modified with zorvek's excellent solution) note you have another error, I believe:

    For x = 1 To RptRows
        ID_Fnd = Application.Match(ReportArray(x, 1), ProdArray, 0)   ' (error is generated here)
        ReportArray(x, 7) = ProdArray(GPN_Fnd, 2)
    Next x
 
Should not GPN_Find be rather ID_Find ?  like this:

        ReportArray(x, 7) = ProdArray(ID_Fnd, 2)

Dave - yes thank you. I did catch the GPN_Fnd v ID_Fnd.

Kevin,

When I try your solution, it is now generating a "type mismatch".  

ReportArray(x,1) - watch is showing as variant/long
Application.Index(ProdArray, , 1) - watch is showing as variant/variant

Although the total solution isn't resolved, I think the maximum points I can give for full resoltuion is not sufficient.  And, yes the solution did resolve the initial question and  created another issue which should be dealt with in another question.

Note that an error occurs on this line:

    ID_Fnd = Application.Match(ReportArray(x, 1), Application.Index(ProdArray, , 2), 0)

because, when extracting a column versus a row, a two dimensional array is returned. The Transpose function solves this problem:

    ID_Fnd = Application.Match(ReportArray(x, 1), Application.Transpose(Application.Index(ProdArray, , 2)), 0)
