Data Consistency

Use

This function enables you to perform a check on data consistency. To guarantee data consistency in case of full or restricted interchangeability, certain master data fields must contain the same values for all interchangeable parts.

Prerequisites

In tables MARA or MARC in the material master, you have defined the fields that have to contain identical data in the List of Common Fields that can be foundin Customizing under Start of the navigation path Logistics ‑ General Next navigation step Interchangeability of Parts Next navigation step Determine Common Fields for Interchangeable Parts End of the navigation path . You can define whether each field is included in the check.

Features

Automatic Consistency Check

When you create interchangeability relationships (fully or restricted interchangeable), change the material master, or perform material exchange, the system checks the list of common fields and writes inconsistencies to an error log.

In Customizing, you can set the message category ( Error or Warning ) for the inconsistency in the error log. If the error log contains only warnings, you can continue processing, otherwise you must correct the inconsistent data.

You set the message category in Customizing by choosing Start of the navigation path Logistics – General Next navigation step Interchangeability of Parts Next navigation step Change Characteristics of System Messages End of the navigation path .

Caution Caution

The check for the common base unit of measure is always carried out (the check behavior cannot be changed in Customizing). If the check ascertains that the units of measure for the materials are not all the same, an error message is raised.

End of the caution.

Note Note

To resolve inconsistencies in the material master you can save your changes despite error messages from the data consistency check if the authorization object ADPIC_CFC is assigned to your user profile. For example, an FFF class contains four parts, two with unit ‘liter’ and two with unit ‘cm’. If you try to change one part with unit ‘liter’ to ‘cm’, the system does not allow you to save because the fourth part still has a different unit of measure (liter).

End of the note.
Field Synchronization

The system can copy the common data from a reference part to another part belonging to the same FFF class.

Note Note

If you carry out the field synchronization in test mode without changes to the database, the log displays the possible inconsistencies between interchangeable parts in an FFF class.

End of the note.

The system copies the content of plant-specific fields in the reference part to the same plant, providing you also create the target part in this plant.

Note Note

The system does not create new material master views for the target part. It copies the field content only if the corresponding view to which this field belongs has already been created in the master data of the target part.

End of the note.
