During the planning run of material requirements planning (MD01/MDBT or MS01/MSBT) or during master production scheduling (MD40/MDBS), the control parameters of materials planning that were entered on the initial screen of the transaction (creation indicator "Create purchase req.", "Schedules lines", "Create MRP list" or "Display list") appear to have no effect.
As a result, the single-item planning for a material may return a different result from total planning even if the indicators on the initial screen are the same.
In addition, the following may occur under certain conditions:
A total planning run with the indicator "Create purchase req." set to "Purchase requisition in opening period" (BANER = 2) generates a purchase requisition (PReq) for planning on a working day. However, for planning on a non-working day, it generates a planned order.
This can occur, for example, for materials planned using consumption-based planning with an opening period from the scheduling margin key of 0 days.
Creation indicator, material requirements planning run, MRP run, materials planning, material requirements planning, MRP, MD01, MD02, MD03, MD40, MD41, MD42, MDBT, MDBS, requirements planning, planned order, purchase requisition, req, PL-AUF
Single-item planning and total planning follow a different logic in relation to the creation indicators.
This is also described in the documentation for production planning/material requirements planning (Chapter 4, Section 2) and in the Implementation Guide (IMG).
Single-item planning:
The specified creation indicators apply in general.
Total planning:
The specified creation indicators are default values.
For materials with an MRP group, the values from the MRP group apply (if they exist).
The creation indicator for schedule lines can be determined additionally for each plant. This is used if nothing is determined using the MRP group.
Therefore, the priority is as follows:
- 1. MRP group
- 2. Plant
- 3. Initial screen
Solution
Check the settings in Customizing for MRP:
- 1. Planning -> Creation Indicator
- 2. Planning -> Procurement Proposals -> Define External Procurement -> Plant:
Creation of delivery schedules.
- 3. Planning -> Activate Runtime Statistics
With a MODIFICATION, the logic of the total planning run can be transferred to the single-item planning transactions. The modification is specified in the attachment.
As of Release ECC 5.0, this modification can also be replaced by implementing the BAdI method ADJUST_PLANNING_PARAMS (BAdI MD_MRP_PARAMETERS).
- An opening period of 0 days means that, together with the indicator "Create req. order" from "2", purchase requisitions can be created only if the opening date is the same as the planning date.
- For reorder point planning, the requirement date is set to the planning date when there is a shortfall of reorder point.
- Therefore, if scheduling is carried out on a non-working day, the requirement date is set to a non-working day and the delivery date or start and opening dates are set to the previous working day.
As a result, the opening and planning dates no longer fall on the same day and the system generates corresponding planned orders.
To avoid this phenomenon, you should always maintain the purchase requisitions creation indicator in the planning group for the affected materials or you should maintain an opening period greater than 0.
