Hello Raju,
You can control the sequence of your operations at the Confirmation.
Go to t-code OPK4, and check the options that you have for Operation Sequence.
Check of operation sequence in order
Defines whether a system message is to be issued when the operation sequence is not adhered to and if so, which type of message. This key only applies to confirmations at operation level.
Dependencies
To find out whether the operation sequence has been adhered to, the following checks are carried out: Have preceding operations already been confirmed? Does the confirmed yield from the preceding operations exceed the total confirmed quantity of the operation to be confirmed?
Note that for planning, the operations are always plan in sequence, except you have overlapping or an alternative sequence.
Kind Regards,
Mariano
