The question is not very clear, however I guess it has to do with the FRSET and FSET parameters in the map definition.
Basically, if you do not use FSET for your input fields, then the MDT flag is set on only when something is entered in the field. This flag stays on until you reset it, unless you use FRSET. In that case, all the flags are reset and you will not receive again the value(s) entered.
Try removing the FRSET and tell us if your condition is better.
FSET: in the ATTRB parameter in the DFHMDF macro.
FRSET: in the CTRL parameter in the DFHMSD/DFHMDI macros.
