SAP Message W_MD028 - No collective purchase orders can currently be created

Diagnosis
No collective purchase orders can be created as other replenishmentprocesses (for example, create a collective purchase order, orfunctions for store replenishment) are active for the same plant thatyou have chosen.

System Response
Processing is abandoned.

Procedure
You cannot run store replenishment functions and create collectivepurchase orders at the same time as this can lead to inconsistent data.
The parallel site for the create collective purchase order function foridentical distribution centers is not recommended as lock conflictscannot be excluded at later stages in processing.
If you do not want to use this check function, you can switch off thecheck by setting the user parameter 'CPO_NO_TRANS_ENQUEUE' to the value'1'. If you do this, ensure that replenishment processes that arerunning in parallel do not cause complications.
