Hi,
Operating time can be determined for work center based on either standard available capacity or shift sequence or length of cycle. This operating time can be fetched as below.
Get the capacity ID (KAPID) from table CRHD and pass it to table KAPA to get the operating time or shift ID. if it is shift ID then pass that to table TC37A to get the operating time.
Let us know in case of any clarification.
Regards,
Chinna.
