p$TDV:SMPAPI:PGUdf20

Set the parameters of the specified parameter group that are in UNDEF state to ’empty’ values, i.e. texts will be set to ’’ (empty string) and numerical parameters get assigned the value 0. All other parameters of the parameter group remain unchanged.

This function can, for example, be employed in combination with the sales information system SalesManager. With regard to reading and writing in this data base an ePOS parameter in UNDEF state implies an empty data base field (’NULL’) while the parameter will be ignored in the EMPTY state.

Please note:

The parameter group may not contain any indexed parameters.	PGName	String	Name of the parameter group, if the PG is indexed the index has to be stated.
Result:	-
