Use the FM DATE_CHECK_PLAUSIBILITY to check if the passed parameter is a date or not. If an exception is raised it is not a date.

Hi Julian

can you give more details?

Have you a generic string field or do you have a field of which you don't now the type. In this case there is a class that give you runtime the type of a field.

You can play as well with abap operator 'CP' - contain pattern, but I suppose it is the last thing worth doing.

A formatted time field wil be of 8 characters(Along with separators).

A formatted date field wil be of 10 characters(Along with separators).

An unformatted time field wil be of 6 characters(Along with separators).

An unformatted date field wil be of 8 characters(Along with separators).

Find the length.

len = strlen( v_var ).

case len.

when 8.

Write:/ 'Its Time'.

when 10.

Write:/ 'Its Date'.

endcase.

Hi,

use describe

DATA: FLD(8) TYPE N,

F_TYPE.

DESCRIBE FIELD FLD TYPE F_TYPE.

Result: F_TYPE contains the value 'N'.

HI,

DATA: FLD LIKE SY-DATUM,

FLD1 LIKE SY-UZEIT,

F_TYPE(4),

F_TYPE1(4).

DESCRIBE FIELD FLD TYPE F_TYPE.

DESCRIBE FIELD FLD1 TYPE F_TYPE1.

WRITE: F_TYPE,F_TYPE1..

if f_type = 'D'

write 'date'.

elseif f_type = 'T'.

write 'time'.

endif.

Hi erveryone,

sorry, maybe i didn't explain it too detail. I read data from a text file, so all data strings of type c initially. But i wanna check if these data are correct date or time format. How to do that?

Thanks.

if string CP '+++..+'.

...

elseif string CP ':'.

else...

Hi Julian,

You can use the FMs:

DATE_CHECK_PLAUSIBILITY Date plausibility check

TIME_CHECK_PLAUSIBILITY Time plausibility check

for checking the string for validity of date or time.

Usage:

call function 'DATE_CHECK_PLAUSIBILITY'

exporting

date = v_date exceptions

plausibility_check_failed = 1

others = 2.

if sy-subrc <> 0.

Write:/ 'NOt a valid date'.

endif.

call function 'TIME_CHECK_PLAUSIBILITY'

exporting

time = v_time

exceptions

others = 1.

if sy-subrc ne 0.

Write:/ 'NOt a valid time'.

endif.

Regards,

Ravi

before to use one of right solution above, do a MOVE.

MOVE $your_variable$ TO $variable_to_test$

$your_variable$ is a sequence of CHAR(8) or CHAR(10), you know.

$variable_to_test$ could be LIKE sy-datum or something else.

Hi julian ,

just give the example for a string how u are storing the formats for date and time in ur system ,

i mean what is the length of the date field and time field in ur text format

will it be same ,,if so give us a value (or a set of values )to work on a specific logic

cause system takes 8 chars for date field and 6 chars for time field ,,

also ur requirement is asking for a date or time check on a specific string ,

but i cant put the same string for two fields check ...

???

if that is the scenario y dont u put

field string

DXXXXXX,

TXXXXXX,

DXXXXXX,

DXXXXXX,

TXXXXXX,

this way ..

differentiate with a tag

field string+0(1) = 'D', --->DATE FIELD

ELSE TIME FIELD.

regards,

vijay

data date type d value '20061014'.

DATA TIME TYPE T VALUE '154633'.

WRITE (8) TIME USING EDIT MASK '__:__:__'. "Output: 15:46:33

write (10) date using edit mask '__/__/____'.

write time using edit mask '______'.

*my logic is system uses internally 8 chars for date field and 6 chars

*for time field
