Object's physical description: Index = 0 SapGui numeric component type = 21/ 22/ 23

I am re-running some SAP TAO scripts that were created by another user in an older version of TAO (3.0.2, I believe). We've since upgraded to HP ALM 12.01 and TAO 3.0.6. When running some of these tests I occasionally encounter the error above in the QTP run report:

Object's physical description:
Index = 0
SapGui numeric component type = 21

OR

Same as above but comp. type = 22

OR

Same as above but comp. type = 23

I did some searching on google and came across a recommendation that probably the data file is feeding a value in "text" format where SAP is expecting a numeric value (usually, the data file saves most input fields as text). I tried changing the format on the numeric field to number in the data file but this did not help.

Have others encountered this issue? Any ideas on resolution?

Thanks!
