Material Exchange in Stock Transport Orders

Use

You may want to change parts in the stock transport order because the availability check fails for the material that you originally requested. Hence, an interchangeable part that is available can be used instead of the original material.

You can exchange parts in stock transport orders (STO) manually or automatically. You can define the unit of measure in the material master. If the issuing unit of measure is defined in the material master, the subitems are always created in the issuing unit of measure. Otherwise, subitems are created in the base unit of measure.

Features

  • Manual interchangeability in creation of stock transport orders

    Subitems are created with subitem category P. This means that you can only change the quantity or delivery date of the main item.

    When you make such a change, this automatically triggers a new ATP check, which creates new subitems. The ATP popup appears displaying the available exchangeable materials, their available quantities, and you can manually choose the quantity you require.

    Note, that you can also work with existing STOs with subitems with subitem category 8.

  • Automatic interchangeability in stock transport order s

    If the ATP check fails during creation of the STO, the system carries out an automatic material exchange. Automatic material exchange is only possible if you set the reaction of message number 450 (application area 06) to E (error message) or W (warning message). You do this in Customizing for Materials Management under Start of the navigation path Purchasing Next navigation step Environment Data Next navigation step Define Attributes of System Messages Next navigation step System Messages. End of the navigation path

  • Consumption sequence control

    You can now manually adjust the consumption sequence that was defined for automatic material exchange on the ATP popup for STOs. To do this you use the new BAdI BADI_ADPIC_STO_CONSLOG. You can access this BAdI in Customizing under Start of the navigation path Logistics - General Next navigation step Interchangeability of Parts Next navigation step Business Add-Ins (Add-Ins) Next navigation step BAdI: Manual Adjustment of Consumption Logic. End of the navigation path

Prerequisites

In Customizing for Start of the navigation path Logistics - General Next navigation step Interchangeability of Parts Next navigation step Define Settings for Material Exchange and Restricted Interchangeability End of the navigation path , you must set the material exchange to Automatic or Manual for pseudo process code STOME.

Constraints

  • Material exchange with issuing unit of measure is only supported in transaction codes ME21N and ME22N .

  • Material exchange in goods movement transaction MIGO (goods issue and goods receipt) is always done in the base unit of measure.

  • Material exchange in VL10B is only possible if the STO items are created in base unit of measure.

  • Stock transport requisitions do not support interchangeability.
