Functionality
This method supplies a list of meter reading orders or results(MRDOCUMENTDATA) and meter reading reason allocations(MRDOCUMENTREASONS) according to different selection criteria.
Enter one of the following objects as a selection criterion:

• Portion (PORTION)


• Meter reading unit (METERREADINGUNIT)


• Customer (CUSTOMER)


• Contract (CONTRACT)


• Installation (INSTALLATION)


• Serial number (SERIALNO)

Enter a material (MATERIAL) or a register (REGISTER) only incombination with a serial number. If the serial number is not unique inthe system, a selection can only be made if the material is alsoentered.
You use the parameter meter reading document type (MRDOCUMENTTYPE) tocontrol whether meter reading orders or meter reading results areselected. The parameter must be entered.
You can restrict the selection further via the meter reading reason(MRREASON). For meter reading orders you can restrict your selectionusing the target meter reading date (TARGETMRDATEFROM, TARGETMRDATETO)and for meter reading results you can use the meter reading date(MRDATEFROM, MRDATETO).

Notes
Messages are returned in parameter RETURN.

Description
This parameter specifies the number of the contract for which the listof meter reading orders or meter reading results is to be selected.

Description
This parameter specifies the number of the customer for which the listof meter reading orders or meter reading results is to be selected.

Description
This parameter specifies the number of the installation for which thelist of meter reading orders or meter reading results is to beselected.

Description
This parameter specifies a material in order to indentify a serialnumber. Always specify a serial number with the material. If the serialnumber is unique in the system, then it is not necessary to enter amaterial.

Description
This parameter specifies the name of the meter reading unit for whichthe list of meter reading orders or meter reading results is to beselected.

Description
This parameter specifies which lower interval limit is valid for themeter reading date of the meter reading results to be selected.
The upper interval limit is specified by the parameter MRDATETO. If themeter reading results are to be selected on a key date, the lower andupper interval limits must be the same.

Description
This parameter specifies which upper interval limit is valid for themeter reading date of the meter reading results to be selected.
The lower interval limit is specified by the parameter MRDATEFROM . Ifthe meter reading results are to be selected on a key date, the lowerand upper interval limits must be the same.

Description
You use the parameter meter reading document category to specifywhether meter reading orders or meter reading results are selected.Enter one of the following values:


• 1 for meter reading orders


• 2 for meter reading results

Entry of this parameter is obligatory.

Description
You can use the number of a meter reading unit to limit the numbermeter reading orders or meter reading results to be included in thelist.

Description
This parameter specifies the name of the portion for which the list ofmeter reading orders or meter reading results is to be selected.

Description
You can use the number of a register to limit the number of meterreading orders or meter reading results for a serial number that areincluded in the list. Always enter a serial number with this parameter.

Description
This parameter specifies the device serial number for which a list ofmeter reading orders or meter reading results is to be selected.
If the serial number is not unique in the system, you must specify amaterial as well.

Description
This parameter specifies which lower interval limit is valid for themeter reading date of the meter reading results to be selected.
The upper interval limit is specified by the parameter TARGETMRDATETO.If the meter reading results are to be selected on a key date, thelower and upper interval limits must be the same.

Description
This parameter specifies which upper interval limit is valid for themeter reading date of the meter reading results to be selected.
The lower interval limit is specified by the parameterTARGETMRDATEFROM. If the meter reading results are to be selected on akey date, the lower and upper interval limits must be the same.

Description
This table returns the list of all the meter reading orders or meterreading results that meet the selection criteria.

Description
This table returns a list of all the basic meter reading allocations ofthe selected meter reading orders or meter reading results.
