Need some information on CALL statement

[Former Member]

Hello All,

There is a statement in standard program saplfpaym05 in subroutine read_data as follows

CALL 'C_RSTS_OPEN_READ'

ID 'HANDLE' FIELD cs_fbhandle-handle

ID 'CLIENT' FIELD sy-mandt

ID 'NAME' FIELD cc_tsnam

ID 'PART' FIELD 1

ID 'CONV' FIELD ' '

ID 'BINARY' FIELD 'X'

ID 'ALLINE' FIELD ' '

ID 'TYPE' FIELD 'DATA'

ID 'RECTYP' FIELD 'U------'

ID 'CHARCO' FIELD ' '

ID 'PROM' FIELD 'I'

ID 'RC' FIELD cc_rsts_rc

ID 'ERRMSG' FIELD cc_rsts_msg.

What exactly is the statement performing? Is it possible to have different results in development system and quality system? Is it anyhow system dependent statements?

Please suggest.

Thanks and Regards,

Sachin
