 Strategy I: Addition to Existing Stock

Use

When addition to existing stock has been defined as a putaway strategy for a storage type, the system places goods in storage bins that already contain the same material. With this strategy, the system searches for a storage bin in which the material is already being stored. A prerequisite for addition to existing stock is that sufficient capacity still exists in the respective storage bin. If the system cannot find a storage bin with the same material or the capacity of the storage bin will not allow additional quants to be stored, the system switches to the "next empty bin" strategy, that is, it searches for the next available empty storage bin.

The FIFO principle is violated with this strategy; therefore, you should use this strategy when warehouse space is limited.

The strategy for adding to existing stock is illustrated below.

Prerequisites

There are two ways to define addition to existing stock:

  • You use the "addition to existing stock" placement strategy for the storage type.

  • You set the additional stock indicator (Addn to Stock) in the storage type record itself. To change the storage type, see the appropriate section on defining a storage type under Master Data in Customizing for Warehouse Management.

When you define the storage type record to use this strategy:

  1. Enter i in the Putaway Strategy field.

  2. Enter x or m in the Addition to Stock field to allow for addition to existing stock.

  3. You set the indicator in the storage type record with:

    - x if you want addition to existing stock generally allowed

    - m if you want addition to stock based on the indicator in the material master record

    If you enter m then you must set the addition to stock indicator in the material master record. You can set the indicator with an x if addition to existing stock is allowed. If you leave the indicator blank, then additional stock is not allowed for the material.

  4. Enter a numeric code for the type of checking in the Capacity Check Method field to activate capacity checking.

  5. Leave the Mixed Storage field blank. Mixed storage is not allowed.
