How To Fix WXP179 - Die Verknüpfungsmethode kann nicht definiert werden! (-> Langtext)

SAP Error Message - Details

• Message type: E = Error

• Message number: 179

• Message text: Die Verknüpfungsmethode kann nicht definiert werden! (-> Langtext)

Was verursacht dieses Problem?

The current assignment of <DS:DE.WISP_PLMER>planning characteristics</>
to <DS:DE.WISP_PLSCH>planning steps</> corresponds to a global planning
hierarchy that is not a pure tree structure. Consequently, the
proportional factors for distributing plan data between planning levels
are no longer uniquely specified, or they have reciprocal dependencies.

Systemantwort

The link method selected cannot be created.

Wie behebe ich diesen Fehler?

Check the sequence of the planning levels of the source and target
planning steps. The planning levels common to both steps must be in the
same order, without any interruption at the peaks of the selected
planning characteristics. All characteristics of the planning step with
the lower number of planning levels must be contained in the other
planning step.
Example 1:
Planning levels source planning step:
SOrg
DChan
Planning levels target planning step:
SOrg
DChan
Plants
Therefore the linking method disaggregation is possible.
Example 2:
Planning levels source planning step:
SOrg
DChan
Plants
Planning levels target planning step:
SOrg
DChan
Therefore the linking method aggregation is possible.
Example 3:
Planning levels step 1:
SOrg
DChan
Plants
Planning levels step 2:
SOrg
DChan
MatGrp1
MatCl
The linking methods aggregation and disaggregation are <ZH>not
</>possible as the planning level WERKS is not available in step 2 and
Matgrp1 and MatCl are not available in step 1.
Define step 3 with characteristics.
DOrg
DChan
Then the aggregation or disaggregation of planning figures from step 1
to step 3 or step 2 to step 3 is possible and therefore also the
indirect transfer of plan data from step 1 to step 2 and vice versa.
