Difference between Order Header BSD and operation schedule SSD

[Former Member]

Hi,

One of your Client is operating on SAP 4.7

There are some cases where Order Header Basic Start Date and operation Schedule Date are no same.

example:

Present Order Basic Start Date 24.06.2011

Present Order Basic Finish Date 01.07.2011

Forward Schedled order.

Operation 1

Operation 2

Work Center has sufficient capacity and is available to perform work 24hrs.

Using planning board CM10 user dispatches operation 1 to 30.06.2011 and operation 2 to 01.07.2011.

The problem is order basic start date is remaining same i.e. 24.06.2011 and not chaning to 30.06.2011.

Can any one please help in this issue.

Its worth having a look at OSS Note [45433|https://service.sap.com/sap/support/notes/45433] which gives some good information regarding scheduling.

Hi PeteA,

I have gone through the oss note.

The issue is system was working fine till recently, when user came with list of orders where when he dispatched the operation of work order and basis start date of work order didnt get updated.

From change log I could make out that user had used CM10 for scheduling 1st time and then when basic start dated didnt got updated he took list of work order in IW38 and went to planning board and did re-scheduling for changing the basic start dates. but IW38 also didnt work.

Is it the same for all orders/order types?

yes for all order types and also i have observed that most of work order has basic start date as 24.06.2011 when all the operations of orders are scheduled in future dates (date other than 24.06.2011).

The first time scheduling of work order operation is done on 24.06.2011 (CM10) and then after re-scheduling (through IW38) of operation changed the schedule start date but work ordre basic start date remained same i.e 24.06.2011.

Dispite of first time scheduling and then re-scheduling basic start date remained 24.06.2011.

Note: Same profile was selected in both CM10 and IW38 while accessing planning board.

Try going into IW32 and performing a reschedule to see what happens

same set of work orders when i am scheduling using cm10 and iw32 basic start date is changing and becoming same as schedule start date.

but we are trying to analyze what went wrong that on 24.06.2011 user when scheduled work order basic start date remained same and operation got scheduled with different date.

[peter_atkin]

Did they set any restriction dates (e.g. Must start on...) on the operation(s)?

PeteA

[Former Member]

there are no restriction set for operations.

Also at same time i have raised an oss message for sap to looking this issue.
