System call update

[Former Member]

Hello,

I'd like to update system call CAL_CONVERT_DATE_TO_FDATE or programm new version by myself in case there is no update.

What I want in fact is recognize that certain day is a work day. This could be done by function module DATE_CONVERT_TO_FACTORYDATE which lead to mentioned system call.

This function module doesn't return our new holidays (for factory calendar 'CZ').

Where can I obtain some update? Or, how to program new version?

Concerning programming new version, I read help and found there notice about file sapactab.h, where should be system call noted. I can't find this file in filesystem and either source files and also don't know how to link compiled source files to SAP kernel.

Can anybody help me?

Best regards,

Hi Josef,

In our system we have defined several custom calendars 'Z1' - 'Z6', all with their own definitions on holidays. The function module you mentioned works fine even for the custom defined calendars.

So are you sure the calendar CZ has been defined correctly?

Hi John,

No, I'm definitely not. Thanks for your responce. I'm newbie in ABAP and R/3. Where can I customize calendars?

Hi Josef.

Go to customizing (transaction SPRO); Choose a project or hit F5.

You will find the calendar customizing in General Settings->Maintain calendar.
