BRAN_DIR_CREATE won't work if application server is not UNIX.
You can ascertain this by looking at the code below, copied from BRAN_DIR_CREATE function, where UNIX style command line option "-p" is used on "mkdir" command. This "mkdir" command syntax will not be valid on a Windows based application server.
| COMMAND1(9) | = 'mkdir -p '. |
COMMAND1+9(55) = DIRNAME.
CALL 'SYSTEM' ID 'COMMAND' FIELD COMMAND1
| ID 'TAB' | FIELD TABL-*SYS*. |
CLEAR FILE_LIST.
SRVNAME = SPACE.
CALL FUNCTION 'RZL_READ_DIR'
| EXPORTING | |||
| NAME | = DIRNAME | ||
| SRVNAME | = SRVNAME | ||
| TABLES | |||
| FILE_TBL | = FILE_LIST | ||
| EXCEPTIONS NOT_FOUND | = 1 | ||
| ARGUMENT_ERROR = 2 | |||
| SEND_ERROR | = 3. |
