How To Fix WPOS_INBOUND_NO_LIST003 - No MRP type determined for creation of MARC for art. &1 site &2

SAP Error Message - Details

• Message type: E = Error

• Message class: WPOS_INBOUND_NO_LIST - Messages for POS Inbound for not listet articles

• Message number: 003

• Message text: No MRP type determined for creation of MARC for art. &1 site &2

What causes this issue?

No MRP type with MRP procedure <ZK>No MRP</> could be determined for the
creation of logistics data while creating the required article master
segments in POS inbound processing for non-listed article <(>&<)>1 and
site <(>&<)>2.

System Response

Article master segments are created and POS inbound processing continues
for the non-listed article. The MRP type is copied from reference
handling but might not be suitable for the article and site.

How to fix this error?

Check the MRP type for the article and site in the article master and
the logistics data for the site and adjust it if required (transaction
MM42).
Create an MRP type with MRP procedure <ZK>No MRP</> so it can be
picked and assigned for non-listed articles in POS inbound processing.
You can also implement BAdI BADI_DATA_FOR_ARTICLE_CREATION for setting
the MRP type of the article and site in order to create article master
segments in POS inbound processing for non-listed articles. However
, if no MRP type with MRP procedure No MRP can be determined, this
warning message will still be displayed.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WPOS_INBOUND_NO_LIST003
  
  Text: No MRP type determined for creation of MARC for art. &1 site &2
  
  Meaning / Cause:
  This error occurs during the creation or update of material master data (specifically the MARC table, which contains plant-specific data) when the system tries to determine the MRP type for a material at a particular plant but fails to find a valid MRP type.
  
  Material (&1): The material number for which the MARC record is being created.
  Plant (&2): The plant for which the MARC record is being created.
  The system requires an MRP type to be assigned to the material at the plant level to control the material requirements planning process.
  If the MRP type is missing or not determined (e.g., no default MRP type is maintained, or the inbound data does not specify it), the system cannot proceed with creating the MARC record.
  
  
  Common Causes:
  
  Missing MRP type in inbound data: The inbound data (e.g., from an IDoc, BAPI, or data upload) does not contain an MRP type for the material at the plant.
  No default MRP type maintained: The material master or plant master data does not have a default MRP type assigned.
  Configuration issue: The system configuration does not allow determination of MRP type automatically.
  Customizing missing: No default MRP type is maintained in the material type or plant parameters.
  Incorrect or incomplete master data: The material or plant master data is incomplete or inconsistent.
  
  
  Solution / How to Fix:
  
  
  Check inbound data:
  
  Ensure that the inbound data (e.g., IDoc segments, BAPI parameters, or upload files) contains a valid MRP type for the material at the plant.
  
  
  Maintain MRP type in material master:  
  
  Go to transaction MM02 (Change Material Master).
  Enter the material number and plant.
  Navigate to the MRP 1 view.
  Check if the MRP type field is filled.
  If not, assign a valid MRP type (e.g., PD, VB, etc.) and save.
  
  
  
  Check default MRP type assignment:  
  
  Verify if the material type has a default MRP type assigned in customizing.
  Use transaction SPRO ? Logistics - General ? Material Master ? Settings for Key Fields ? Define Material Types.
  Check if the default MRP type is maintained for the material type.
  
  
  
  Check plant parameters:  
  
  In customizing, check if the plant parameters allow defaulting or require manual entry of MRP type.
  Use transaction OMI4 to check plant parameters related to MRP.
  
  
  
  Review user exits or BAdIs:  
  
  If inbound processing uses custom enhancements, check if any user exit or BAdI is responsible for determining the MRP type.
  Ensure the logic correctly assigns the MRP type.
  
  
  
  Reprocess the inbound data:
  
  After correcting the MRP type, reprocess the inbound data or recreate the MARC record.
  
  
  
  Additional Information:
  
  MRP Type: Controls how the material is planned in MRP (e.g., PD = MRP, VB = Manual reorder point, etc.).
  MARC Table: Contains plant-specific data for materials, including MRP type.
  This error is common in interfaces or data migration scenarios where inbound data is incomplete.
  Always ensure master data consistency before running MRP or inbound processes.
