Well, this is actually a call to the kernal which is C, this call can not be debugged and the source can not be viewed, so it is a little hard to figure out exactly what it does, but sometimes you can guess by the name and the parameters.

It appears that it may read the files from the application server.

Hi,

this is OS function used to read the file from a server directory.

like this

• Start reading

l_fname = '.'. "Mask

CALL 'C_DIR_READ_START' ID 'DIR' FIELD p_folder

ID 'FILE' FIELD l_fname

ID 'ERRNO' FIELD l_ferrn

ID 'ERRMSG' FIELD l_ferrm.

CHECK sy-subrc = 0.

• read Directory

WHILE sy-subrc = 0.

CLEAR l_flist.

CALL 'C_DIR_READ_NEXT' ID 'TYPE' FIELD l_flist-ftype

ID 'NAME' FIELD l_flist-fname

ID 'LEN' FIELD l_flist-fleng

ID 'OWNER' FIELD l_flist-fownr

ID 'MTIME' FIELD l_flist-fmtme

ID 'MODE' FIELD l_flist-fmode

ID 'ERRNO' FIELD l_ferrn

ID 'ERRMSG' FIELD l_ferrm.

CHECK sy-subrc = 0 AND NOT l_flist-fleng IS INITIAL.

l_flist-direc = p_folder.

INSERT l_flist INTO TABLE lt_flist.

• finish reading

CALL 'C_DIR_READ_FINISH' ID 'ERRNO' FIELD l_ferrn

ID 'ERRMSG' FIELD l_ferrm.
