Documentation
Definition
This function module is used to get data for a DataSource that was created using generic data extraction (transaction RSO2). During an extraction process, this function module is called up several times in succession:
- Initialization call up:
Only the request parameters are transferred to the module here (see below). The module cannot transfer any data as yet.
- First read call up:
The request parameters are not transferred again. The extractor returns data typified by the extract stucture in an interface table. The request parameter (I_MAXSIZE) specifies the number of expected rows.
- Second read call up:
The extractor returns data connected to the first data package, again in a package with I_MAXSIZE rows.
- The function module is called up again and again until it calls up the exception 'NO_MORE_DATA'. No more data is allowed to be transferred in the call up in which this exception arose.
The function module must have the following interfaces:
Importing parameters:
I_DSOURCE type SRSC_S_IF_SIMPLE-DSOURCE DataSource
I_INITFLAG type SRSC_S_IF_SIMPLE-INITFLAG Initialization call up
I_MAXSIZE type SRSC_S_IF_SIMPLE-MAXSIZE Package size
I_REQUNR type SRSC_S_IF_SIMPLE-REQUNR Request number
Tables:
I_T_SELECT type SRSC_S_IF_SIMPLE-T_SELECT
I_T_FIELDS type SRSC_S_IF_SIMPLE-T_SELECT
E_T_DATA
Exceptions:
NO_MORE_DATA
ERROR_PASSED_TO_MESS_HANDLER
Notes to the individual parameters:
I_INITFLAG
When the function module is called up for the first time, this parameter is set to 'X', afterwards it is set to ' '.
I_MAXSIZE
This parameter contains the number of rows expected for a read call up.
Example
An example of a function module that meets these requirements is RSAX_BIW_GET_DATA_SIMPLE. A simple method of creating a syntactically correct module is to copy it into its own function group and to copy the top-include rows of RSAX (LRSAXTOP) function group into the top- include for this function group. Afterwards, you need to adjust the copied function module to meet your own requirements.
