Data Types for RFC Communication

For SAP RFC integrations, parameter data types should be defined in SAP ERP as follows.

Category	Name	Type	Description
Export Parameters	LABEL	CHAR255	Label, Label Type, or Label Group
	PRINTER	CHAR255	Device name
	JOBNAME	CHAR255	Unique name for job, echoed in Spectrum
	QUANTITY	INT
	DUPLICATES	INT
Import Parameters	CONFIRMATION	STRUCTURE ID (INT) MSG (TEXT100)	Structure describing the results of the print request
Table Parameters	LABEL_FIELDS	STRUCTURE: LABELNUM (INT) FIELDNAME (CHAR60) FIELDVALUE (CHAR1000)	List of field names and values

The LABELNUM value in the LABEL_FIELDS structure is used to send multiple labels in a single print request. All of the fields belonging to a particular label should have the same LABELNUM value. If submitting a request for a single label Job this value can be 0 for all fields.

Example

The following example shows the structure of LABEL_FIELDS to print one label. There will be a row for each field required.

LABELNUM	FIELDNAME	FIELDVALUE
0	PART_NUMBER	GR1287654
0	CUSTOMER_NUMBER	76234
