The CALLRFC Procedure

DESCRIBE FUNCTION Statement

Reads metadata about an RFC and writes the information to the SAS log or to a SAS data set (using ODS). The DESCRIBE FUNCTION statement can be called multiple times within a PROC CALLRFC step.

DESCRIBE <FUNCTION> 'function-name' <SHORT>;

Required Arguments

function-name: specifies the name of the ABAP function. The function name is a literal and it must be enclosed in quotes. The function name is converted to uppercase characters.

Options

SHORT: specifies that parameter metadata only is printed in the SAS log. The field metadata is not printed.

Details

General Attributes

In SAS listing output, the function name is printed. If ODS output is redirected to a SAS data set, the structure of the data set is as follows:

Name	Type	Label	Description
Label1			contains the attribute name, 'Function Name'
cValue1			contains the value for character attributes, for example, 'RFC_SYSTEM_INFO'
nValue1			contains the value for numeric attributes. For the CALLRFC procedure no numeric attributes are listed.

Parameters

For each parameter, the following information is provided. If ODS output is redirected to SAS data sets, the structure of the data set follows:

Name	Type	Label	Description
class	Text 1	Class	Parameter class: I for input O for output T for table
name	Text 32	Parameter	Parameter name
intlen	Number 8	Internal length	Internal length in byte (ABAP)
leng	Number 8	Length (number of characters)
outlen	Number 8	Output length
decimals	Number 8	Number of decimal places
datatype	Text 5	ABAP data type
inttype	Text 1	ABAP data type (internal)
label	Text 256	Label
type	Number 8	Variable Type	SAS variable type 0 - no type, might be a structure 1 - numeric 2 - character
length	Number 8	Variable Length	SAS variable length
format	Text 32	Variable Format	SAS variable format
formatl	Number 8	Format Length	SAS variable format length
formatd	Number 8	Number of Format Decimals	SAS variable format decimals
informat	Text 32	Variable Informat	SAS variable informat
informl	Number 8	Informat Length	SAS variable informat length
informd	Number 8	Number of Informat Decimals	SAS variable informat decimals

Columns

For each column of each structure (input, output, and tables) the following information (see table) is listed. If the ODS output is redirected to data sets the structure of the data set follows:

Name	Type	Label	Description
parm	Text 32	Parameter
name	Text 32	Column
offset	Number 8	Offset
leng	Number 8	Length (number of characters)
intlen	Number 8	Internal length
outlen	Number 8	Output length
decimals	Number 8	Number of decimal places
datatype	Text 5	ABAP data type
inttype	Text 1	ABAP data type (internal)
label	Text 256	Label
type	Number 8	Variable Type	SAS variable type 0 - no type, might be a structure 1 - numeric 2 - character
length	Number 8	Variable Length	SAS variable length
format	Text 32	Variable Format	SAS variable format
formatl	Number 8	Format Length	SAS variable format length
formatd	Number 8	Number of Format Decimals	SAS variable format decimals
informat	Text 32	Variable Informat	SAS variable informat
informl	Number 8	Informat Length	SAS variable informat length
informd	Number 8	Number of Informat Decimals	SAS variable informat decimals
